Systems of the Human Body

There are many systems in the human body. These systems include the circulatory system, respiratory system, immune system, skeletal system, excretory system, urinary system, muscular system, endocrine system, digestive system, nervous system and the reproductive system. I will give the basics on each system.
The circulatory system includes the heart and blood vessels. It pumps blood to the body which sends oxygen to the cells and takes away waste. The respiratory system includes the nose, trachea and lungs and is needed to deliver oxygen to the blood and also to take away carbon dioxide from the body. Then, there is the Immune system which helps to keep the body stay well and free from diseases. In the immune system, are different kinds of cells, proteins, organs and tissue like our skin which is the very first line of defense for the immune system. The skeletal system includes the bones and helps us stay upright and able to move and protects the body’s organs along with the muscular system which is made up of the muscles. The excretory system includes the lungs, large intestine and kidneys. Its job is get rid of the waste that the body makes in the form of exhaling carbon dioxide from the lungs, feces from the large intestine and urine from the kidneys. . The urinary system is made up of the bladder and kidneys and is actually part of the excretory system as it rids our bodies of waste in the form of urine. The digestive system includes the mouth, esophagus, stomach and intestines and is responsible to breaking down our food to be delivered to our body in the different areas it needs to go. The endocrine system is made up of glands and they tell your cells of your body what they need to do. The nervous system is made up of brain, spinal cord and nerves. The nervous system is like a control system for our bodies and…...

...We often do not think of how we perform actions like walking, sitting or even flinching when you get a cut on your finger but these actions are actually controlled by a very complex set of internal circuits similar to a light when you turn on the switch that is called the central nervous system (CNS). There are three major parts that make up the CNS, they are the brain, spinal cord and peripheral nervous system (PNS). The CNS transmits information to the brain through transmitters and receptors that are all throughout our body and emits a command to a muscle or gland if necessary. Sometimes the answer comes instantly as a reflex or automatic response or other times may take considerably longer, requiring cooperation among many parts of the brain. (Brodal, 1992). The central nervous system not only transmits movement but also creates an equilibrium system that keeps the body balanced as you perform actions like walking or bending. To do this the cns sends electrical impulses to certain muscle and joints to create a balanced position for the body. (E. Bizzi, 1992) Traumatic brain injury (TBI) has a very dramatic affect on the person and their family whether permanent or temporary but what exactly causes it. Brain damage following a traumatic injury is a result of direct or immediate mechanical disruption of brain tissues, or primary injury and indirect or delayed mechanisms which involve initiating the acute inflammatory response, edema formations and swelling.

...n your own words, describe how the human skeleton supports the human body. The human skeleton is the framework of the human body. It supports the softer tissues, provides points of attachment for most skeletal muscles and protects many vital organs. It also maintains the body’s’ shape. The skeleton is made up of bones that can be categorised according to one of five functions that they perform; • Shape and support; The skeleton provides the shape and support that gives the body its shape. As well as providing gravitational support, it supports the softer tissues and provides points of attachments for most skeletal muscle. • Movement; Some bones provide leverage for movement. Most of the bones are connected to other bones at flexible joints, which allow the skeletal framework a high degree of flexibility and movement. The bones are attached to tendons of the skeletal muscle and the ligaments of the joints. They then act as levers and pulleys to aid the contraction of the skeletal muscles into movement. • Protection; The skeleton provides protection for the body’s vital organs, reducing risk of injury to them. Blood production; Red blood cells and some white blood cells are manufactured by the bone marrow which is found in the cavities of some of the larger bones. Haematopoiesis is the formation of blood cells. This normally takes place in the red marrow of the bones. Each bone consists of a compact outer shell and a spongy centre. The centre contains the bone marrow......

...the systems in the human body are vital to our survival and well-being. If you take away the functions of just one of these systems our whole body will cease to work properly. The main systems of the human body are the nervous, endocrine respiratory, circulatory, immune, digestive, excretory, skeletal, muscular, and the reproductive systems. They all work together in harmony and unison to keep us alive. The nervous and endocrine systems are what control most of the body. The nervous system includes the brain, spinal, cord and nerves. The endocrine system consists of various hormonal glands such as the pituitary. These two systems interact closely since they both have a part in controlling the body. They work together to aid the body in performing its numerous functions and giving it commands. The respiratory and endocrine system works with all the system by controlling their actions and how they perform their tasks. It moves the muscles of the muscular system and controls all motor movements. The endocrine builds up the bones of the skeletal system and produces the hormones that make the reproductive system mature. The nervous system helps the circulatory system by controlling the amount of glucose in blood and blood pressure. It also regulates breathing for the respiratory system. The digestive system is also aided by the sensory nerves in the mouth which help it decide if food should be released back upward. The nervous and endocrine systems......

...The Four Basic Human Body Structure Units and Their Functions The four basic human body structure units are cells, tissues, organs and systems which, all working together make the human body function. The cells are the core structure that make up the human body, although there are many different shapes, sizes and types they consist of three main parts, the cell membrane which maintains the shape of the cell and separates and controls the movement of material into and out of the cell, the nucleus which contains the cells DNA and determines its structure and function and the cytoplasm which is the fluid in the cell that contains the organelles which perform its specific functions. There are many cell functions dependant on the cell type but the generalized functions are molecule transport, reproduction and protein synthesis. Molecule transport is the transfer of material through the cell membrane, there are two ways this happens, diffusion and active transport. Diffusion is when molecules such as oxygen, carbon dioxide and water move from areas where there are many of the particles to areas with less. Active transport is when substances are at lower concentration and require energy to be transferred. There are two means of active transport, endocytosis which is the movement of molecules from outside to inside the cell and exocytosis which is movement of molecules from inside to outside the cell, both performed through the formation of vesicles which package the......

...Bodily Systems and the Spatial-Functional Structure of the Human Body Barry Smith, PhD1,2, Igor Papakin1, Katherine Munn1 1Institute for Formal Ontology and Medical Information Science Faculty of Medicine, University of Leipzig, Leipzig, Germany 2Department of Philosophy, University at Buffalo, Buffalo, NY, USA Abstract. The human body as conceived by medical science is a system made of systems. The body is divided into bodily systems proper, such as the endocrine and circulatory systems. These are subdivded into many subsystems at a variety of levels whereby all systems and subsystems engage in massive causal interaction with other systems and subsystems. In this essay we offer an explicit definition of bodily system, and explicit means for understanding these causal interactions. Whereas informality is acceptable in documentation created for human beings, it falls short of what is needed for computer representations. In our analysis we will define bodily system, and will take some first steps toward understanding the causal relationships bodily systems have with their subsystems. 1. Introduction Ontology plays an increasingly significant role in work on terminology and knowledge management systems in the domain of biomedical informatics, and we hold that it will play an essential role in biomedical research of the future. The term ‘ontology’ must, however, be understood in the right way [1]. The dominant paradigm might be referred to as......

Human Body System

...The Digestive System is made up of organs that break down food into protein, vitamins, minerals, carbohydrates, and fats, which the body needs for energy, growth, and repair. After the food is chewed and swallowed, it goes down the throat and enters the stomach. It is further broken down by powerful stomach acids. From the stomach the food travels into the small intestine. This is where your food is broken down into nutrients that can enter the bloodstream through tiny hair-like projections. The excess food that the body doesn't need or can't digest is turned into waste and is eliminated from the body. The digestive system is a key component of everyday life due to the fact it handles all the intake of water and food sources. The Endocrine System is made up of a group of glands that produce the body's long-distance messengers, or hormones. Hormones are chemicals that control body functions, such as metabolism, growth, and sexual development. The glands, which include the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, thymus gland, pineal body, pancreas, ovaries, and testes, release hormones directly into the bloodstream, which transports the hormones to organs and tissues throughout the body. This system is not a major component but does play an important role in the growth process. The Lymphatic System is also a defense system for the body. It filters out organisms that cause disease, produces white blood cells, and generates disease-fighting...

...Body Systems Preparation 2 We learned human eyes are spherical organs. Six small muscles attach the eye to the socket. According to Chiras(2013) “The wall of the human eye consists of three layers. The outermost is a durable, fibrous layer, which consists of the white off the eye(sclera). In front, this layer is clear and forms the cornea. The cornea lets light into the interior of the eye. The middle layer consists of cells containing a large amount of a dark pigment, known as melanin. In front, the pigmented layer forms the iris, the colored portion of the eye visible through the cornea. Looking in a mirror; you can see a dark opening in the iris called the pupil. The pupil allows light passing through the cornea to enter the eye. The blackness you see through the pupil is the pigmented region, just mentioned, and the pigmented section of the retina, discussed shortly. The iris contains smooth muscle cells. These cells contract and relax to adjust the amount of light entering the eye. When it is dark, for example, the muscles relax, which allows the pupils to dilate so more light enters. In bright light, just the opposite occurs. The innermost layer of the eye is the retina. The retina consist of an outer, pigmented layer and an inner layer consisting of photoreceptors. The photoreceptors of the retina are highly modified nerve cells that detect light. Two types of photoreceptors are present in the retina; rods and cones. The rods, so named because of...

...The Human Body –Stages of Child Development p.54 Write a summary of each of the 3 stages of childhood development. Two and a half-year-old Moira learns 10 new words a day. Quickly she also learns self-awareness. Unfortunately, this means she can articulate her needs and throw tantrums if she does not get what she wants. Maybe children have an instinctive knowledge for language and get the grammar right virtually all the time. Moira make word herself for plural for mouse by adding an S. So how to kids soak up new language so fast? The reason is that children always felt serious dangers. So they, by instinct, learn the vast range of words as fast as possible to better provide against squalls, to survive. Theory of mind is our ability to understand that other individuals have their own minds, with different thoughts, feelings, desires, emotions, motivations and goals. It’s a crucial ability for creating and maintaining a complex society and as far as we know humans are the only species that can do it. This important, complex and uniquely human ability is based on being able to recognize that I am separate from you; that I am a distinct, physical entity that can be recognized in the mirror. Chimpanzee can recognize themselves in the mirror but monkeys cannot. Ostensibly this makes sense, since chimpanzee have bigger brains than monkeys and display a wider range of more complex behavior. There’s even some suggestion that chimpanzees have a sort of theory of mind. But humans......

...BTEC 90 Credit/Extended Diploma in Public Services Unit 5 Physical Preparation, Health and Lifestyle for the Public Services Learner Resource Pack Introduction The human body is a very complex piece of machinery. It is made up of many different systems that work together to allow us to take part in a wide range of sports and everyday activities. It is important that anyone working with clients in the sport and exercise industry has a good understanding of how each of these systems works and copes with the stresses of exercise. This unit will explore the structure and the functions of the skeletal, muscular, cardiovascular and respiratory systems and how each of them is affected by exercise. It will also focus on the energy systems and their role in sport and exercise performance. Section One - The Structure and Function of The Skeletal System and How it Responds to Exercise Part 1.1: The structure of the skeleton system The skeleton provides us with a complex framework of bones, joints and cartilage without which we could not stand upright or move. It consists of 206 bones which can be divided into the axial and appendicular skeleton. The axial and appendicular skeleton The axial skeleton provides the supportive structure of the skeleton and is made up of the skull, vertebral column, sternum and ribs. The appendicular skeleton is made up of the upper limbs, shoulder girdle, lower limbs and hip girdle and......

...structure and function of the 11 systems within the human body. It will detail the interrelationship between the nervous system and the musculoskeletal system and between the circulatory system and the lymphatic system. It will then explain the roles of the circulatory and lymphatic systems in the immune response and the role of hormones in metabolism. Human Body Systems The human body is made up of 11 separate but interconnected systems (Sherwood, 2007). These are the skeletal, muscular, circulatory, respiratory, digestive, excretory, nervous, integumentary, immune, endocrine and reproductive systems. The success and survival of the human body is dependent on the ability of separate body systems to work together. The skeletal system provides structure for the human body, stores minerals, produces blood cells and provides protection for delicate organs (Kelly, 2004). 206 bones are connected with ligaments, muscles and tendons, with cartilage, a softer cushion like material, providing protection in jointed areas. Body movements are controlled by the muscular system, with these muscles being connected to bones via tendons (Adams, 2004). Stimulation of these muscles by the nervous system causes contraction and the resulting movement of bones to which they are attached. A number of involuntary muscles ensure the respiratory and circulatory systems continue with contraction of the heart and lungs (Adams, 2004). The heart is central to the circulatory system and acts as to......

Explain why nutrients are important in living systems. Describe how the availability of nutrients affects the productivity of ecosystems. Lesson Summary Recycling in the Biosphere Matter, unlike energy, is recycled within and between ecosystems. Elements pass from one organism to another and from one part of the biosphere to another through biogeochemical cycles, which are closed loops powered by the flow of energy. The Water Cycle Water moves between the ocean, the atmosphere, and land. Evaporation is the process in which water changes from a liquid to a gas. Transpiration is the process in which water evaporates from the leaves of plants. Nutrient Cycles The chemical substances that an organism needs to survive are called nutrients. Like water, nutrients pass through organisms and the environment. Carbon Cycle: Carbon is a key ingredient of all organic compounds. Processes involved in the carbon cycle include photosynthesis and human activities such as burning. Nitrogen Cycle: Nitrogen is needed by all organisms to build proteins. Processes involved in the nitrogen cycle include nitrogen fixation and denitrification. • In nitrogen fixation, certain bacteria convert nitrogen gas into ammonia. • In denitrification, other soil bacteria convert......

...cells.What is the function of carbohydrates? Carbohydrates provide the body with a source of fuel and energy that is required to carry out daily activities and exercise. Any extra energy is stored in the body until its needed. Our bodies need a constant supply of energy to function properly and a lack of carbohydrates in the diet can cause tiredness or fatigue, poor mental function and lack of endurance and stamina. Carbohydrates are also important for the correct working of our brain, heart and nervous, digestive and immune systems. Digestion: food enters the mouth, being chewed by teeth, with chemical processing beginning with chemicals in the saliva from the salivary glands. This is called mastication. Then it travels down the esophagus into the stomach, where hydrochloric acid kills most contaminating microorganisms and begins mechanical break down of some food (e.g., denaturation of protein), and chemical alteration of some. The hydrochloric acid also has a low pH, which allows enzymes to work more efficiently. After about an hour or two in humans, the resulting thick liquid is called chyme. Chyme will go through the small intestine, where 95% of absorption of nutrients occurs, through the large intestine with waste material eventually being eliminated during defecation. Saturated Fats: Also known as the "bad fats," saturated fats increase the total LDL and blood cholesterol levels in the body. When consumed in high amounts, these fats are believed to accumulate......

Approaches to Human Body

...Approaches to studying the Human Body Approaches to studying the Human Body There are seven approaches one can take to study the human body. Those approaches are • Body planes and body directions • Body cavity • Quadrants and regions • Anatomy and physiology • Microscopic to macroscopic • Body systems • Medical specialties The body planes and the body directions are used when trying to describe the location on the body it can also be called anatomical directions. For example anterior is used for front or in front of and posterior is for after, behind, following. The body cavity is being used when studying any fluid filled space in the multicellular organism. Like the pelvic cavity, ventral cavity dorsal cavity and so forth. Regions and quadrants are used to determine what part of the body you are studying, we determined that with planes there is front and back and now with regions and quadrants it gets a little more specific. Anatomy and physiology are used to determine how each part of the body work and why it works the way it does. Microscopic to macroscopic is the study of the bodies smallest parts and how they come together to make a large complex system. Body systems are how the organs function in the body, how the heart beats how we breathe. Medical specialties are the treatment for a specific area in the body. • In health care each organizational approach is used differently. The quadrant system is used more so when health care workers are......
