How The Body Systems And The Components That Make Up That System

The anatomy and physiology of the human body explains that muscles are attached to the skeleton. They work like hinges or levers to pull or move particular joints when a muscle contracts, pulling the joint in the direction it is designed to move. Parts of muscles move antagonistically, that is, when one contracts, its opposite member relaxes to allow movement. Muscles can become slack, making movement slower and more difficult.

“Homeostasis in a general sense refers to stability or balance in a system. It is the body's attempt to maintain a constant internal environment. Maintaining a stable internal environment requires constant monitoring and adjustments as conditions change” (Human Physiology/Homeostasis, 2016). Negative feedback will operate to return Mrs. Loiselle’s body back to homeostasis in such a way her body, system responds in which it reverse the direction of changes. Since negative feedback tends to keep things constant, it allows the maintenance of homeostasis. As Mrs. Loiselle’s fainted by going for the run without eating something from last evening that made her week and she lost an enormous amount of energy in her exercise through sweating continuously. That made her dehydrated and because

Homeostasis is a characteristic of life in which all Living things maintain. some of the traits of Homeostasis are perspiration and some form of breathing and other natural body functions. An example of a negative feedback mechanism is a Thermostat If the heat is turned on and is set at 80 degrees the heat is turned on, If the temperature drops below 80 degrees, After the heater heats the house to 80 degrees, it shuts off keeping the desired temperature. An example of a positive feedback system is when a baby is born. while the mother is in labor, a hormone is released that boosts and quickens her contractions. The more contractions causes more of that Hormone to be let out and it continues to goes on until the

The circulatory system would transport nutrients and oxygen to all the cells in the body. Organs include, heart, veins, and arteries. The respiratory system exchanges gases, like carbon dioxide, and oxygen so that the body will function properly. These two systems work together to get oxygen to move blood, to work out many organs in the body. Air goes in and out by the mouth or nose and comes in and out of the lungs. What comes in is oxygen, and that oxygen moves blood to the lungs. What comes out is carbon dioxide, and that moves the blood to the

The digestive, cardiovascular and respiratory system are all interrelated in order to make the human body work effectively and efficiently. The cardiovascular system and the respiratory work together by performing gas exchange which is passing of oxygen from the alveoli into the blood flow and then the carbon dioxide passes trough the blood flow and is breathed out from the body. If gas exchange didn’t take place then it will result in the cells dying. There are many other body systems that interrelate with each other e.g. the nervous system is interrelated with the muscular system.

All of these different parts work like organs in a living body, and they are all required and needed to keep the body/organism in a working condition.

Organ system is a group of organs that work together to perform a certain task.  Humans

The body has different organs that work together and they make up a system such as the

The circulatory system and the respiratory system work closely together to ensure that organ tissues and systems receive enough oxygen. Oxygen is required for cellular functions such as cell respiration. This is so the body’s organs and cells can work at fully; it is done by releasing chemical energy with in stored foods. The air breathed in and held in the lungs is transferred to the blood. The blood is circulated by the heart, which pumps the oxygenated blood from the lungs to the body organs and returns with deoxygenated blood.

Complete the table below for the required systems listed. You are required to list four to six of the main organs of each body system, one or two sentences explaining the function of the system itself in your own words, and a short list of five to six major diseases that afflict each system.

Homeostasis is a biological process that maintains a constant internal environment, regardless of what is going on in the external environment. This process ensures the bodily functions and chemicals are kept in a state of balance which in return allows the body to function optimally. Homeostasis requires coordination of the hormonal (endocrine system) and nervous systems, which together regulate the activity of the body’s organ systems. The regulatory activities are constantly adjusted in response to stimuli (change) from both the internal and external environment. A change influenced by the external environment can cause a state in the body that will take it away from the normal, the body will act to counteract this change and return the internal environment back to a steady state. This is negative feedback. Negative feedback has a stabilising effect reducing changes from a set point and returning internal conditions to a steady state. Most body systems e.g. controlling blood glucose levels, obtains homeostasis through negative feedback which makes the negative feedback system critically important in obtaining homeostasis. However there is also positive feedback which is a system that results in the escalation of a response to a stimulus. It causes instability in the system and is used when there is a specific outcome required. Positive feedback ceases once the natural resolution is reached e.g. baby is born, pathogen is destroyed, blood clot forms. This system is not used

All 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 muscular system also helps to keep us warm and keep us at the correct temperature. Thermoregulation is a process that allows your body to maintain its correct temperature of 37 degrees c. Muscles contribute to your bodies temperature because they receive messages from the brain when you are cold. Our bodies response to being cold is shivering which warms you up on the other hand if you are

Smooth muscles are found in the skin, internal organs, reproductive system, major blood vessels, and excretory system. Skeletal muscles are composed of long fibers surrounded by a membranous sheath, the sarcolemma. Since the Skeletal muscles are under control by whom ever they belong to are called voluntary muscles. This muscle is attached to two or more bones which are then attached to the skeleton by tendons. For example, head and neck muscles; contraction of these muscles produces facial expressions and head movements. They are also responsible for speech and swallowing. Skeletal muscles are the main muscles which move your body. Muscles nearly always work in coordinated groups; contraction of one muscle is accompanied by relaxation of another, while other muscles stabilize nearby joints. Then the last of the muscle types is the Cardiac Muscle or the involuntary muscles. Cardiac muscles are not under conscious control they do not react by a persons decision or movement. and are connected to the nervous system which are stimulated by autonomic impulses. Cardiac muscles are found in your internal organs like the heart or the intestine. For example; they include muscles that propel food through the intestine and those that control sweating and blood pressure.

Homeostasis uses a feedback mechanism called negative feedback meaning that it works from feedback it receives about changes that need to be made. The mechanism responds to the normal range of environmental factors because the receptors sense that a change needs to be
