The Principles Of Homeostasis And The Contribution Of The Cardiovascular System

* Stress is "a force that is external in nature that causes strain upon the body, both physical and emotional."

The human body reacts externally or internally in the way of physiological responses. When we experience one of these stressors the physiological responses job is to prepare the body to deal either by adapting to it or simply surviving it. This can promote a functional alteration in the organs normal function.

Another word used to describe a heart attack is myocardial infarction, cardiac infarction and coronary thrombosis. A heart attack is the death of a part of the heart caused by the loss of blood supply. The blood supply is usually gone due to a coronary artery being blocked by a blood clot. When a part of a heart artery breaks a blood clot forms around the piece. This blood clot can block the blood flow through the heart muscle. When the heart muscle needs oxygen it is called ischemia. When damage of a part of the heart muscle happens it’s called a heart attack. During a heart attack damage occurs depending on the size of the area blocked by the blood clot as well as the time between the actual heart attack and the treatment. Even though the heart may be hurt, the rest of the organs work with no problems. However, it will not pump as much blood as it used to in order to supply the same amount of blood to all of the parts of the body.

Homeostasis is the way that a system functions to control and maintain the body’s physiological systems. This system consists of:

unit 5 P5- Explain the concept homeostasis with reference to the control of heart rate, breathing rate, body temperature and blood glucose.

Homeostasis is the process of maintaining a fairly constant interval environment. Homeostatic mechanisms help us to be independent of our external environment. It helps us regulate our body temperature, pH, concentration of dissolved substance in the body fluids, concentration of glucose in blood, concentration of oxygen and carbon dioxide in the blood and body fluids, blood pressure and concentration of metabolic wastes. Without it, we wouldn’t be able to survive and adapt to our environment.

Homeostasis is described as the body's ability to maintain internally stable conditions. Each organ plays a huge role in maintaining this stability.

Stress is simply a fact of nature—forces from the outside world affecting the individual. These forces are related to both internal and external factors. External factors include the physical environment, such as one’s job, school, or home, relationships with others and all the situations and challenges one confronts on a daily basis. Internal factors include one’s overall health and fitness levels, diet, emotional well-being and the amount of sleep one gets. How an individual responds to these factors vary, as well as the symptoms associated with it.

In this assignment I will be explain the concept of homeostasis and how it is used in the body. Homeostasis is when the body attempts to maintain an internal balance. Homeostasis is the maintain of constant internal conditions. All living organisms regulate their internal environment and show homeostasis to some extent. It maintains the levels of a wide range of features such as temperature, PH, water potential and blood glucose concentration. Many of these mechanisms rely on negative feedback. This is the process in which departure from the set level is detected by receptors. Homeostasis is the conditions inside the body must be controlled within narrow limits. These conditions include water content, ion content, and body temperature and blood glucose concentration. They are controlled by the stimulation from the nervous by chemical receptors in the blood and the hormones. Regulating the function of organs in the body, these help the glands to maintain the body homeostasis. Influences the cells, organ and the function of our bodies. The system looks after our growth, development, tissue function, metabolism and the sexual, reproductive process. Homeostasis controls the body temperature control, pH balance, water and electrolyte balance, blood pressure, and respiration. It is mostly affected in heat, cold, moisture, dryness, nourishment or deprivation, what you eat, when you eat and proper digestion and elimination all affect what

Homeostasis Homeostasis works to maintain the organism's internal environment, where the body's processes are able to function at a level that would allow life to continue in that organism. The three systems which are controlled by homeostasis are the respiratory, cardiovascular, and muscular systems. Changes to the cardiovascular system are often a result of changes in the activities of other systems.

capabilities, resulting in biopsychological charges that may make him/her of risk for disease. Effects may vary from one person to another. (Niabi; H. et. al., 2013)

The circulatory system maintains homeostasis, by the controlled and continuous flow of blood that reaches each cell in the body. This allows the mechanisms within the circulatory system to ensure that every cell maintains a constant and balanced internal environment!

Homeostasis is the term used for the body’s ability to maintain a constant balance within the internal environment. Maintaining a well balance internally is mandatory in order for the proper functioning within the body can occur. That reason being so that the enzymes can still manage all metabolic activity essential for life which is very sensitive to changes in their environment. This constant state must be maintained in spite of changing the external environment. Sometimes there are cases where homeostasis will fail to maintain its balance due to what happened outside of the body. In result of failing in cultivating a steady balance, it can lead to multiple mishaps. The article, “What if Homeostasis Fails,” written by David H. Nguyen and

Stress affects the body in many different ways. Many doctors estimate that stress is involved in more than half of all illnesses (Sapolsky, 21). Stress may cause or prolong an illness or increase its severity. Epinephrine and norepinephrine are hormones that are released during a stress reaction that affect organs throughout the body. As a result from the hormones being secreted, the heart begins to beat more rapidly, muscle tension increases, blood pressure raises, and heavy breathing may occur. This reaction is known as the fight-or-flight response. The fight-or-flight response energizes the body to either confront or flee from a threat. Heredity, learning, and injuries all play a role in determining where or when a stress related illness may occur in a particular individual (Sapolsky, 22).

First I would like to start out with clarifying the different kinds of homeostasis in greater detail.
