Concept Of Homeostasis

721 Words2 Pages

To understand how the human body works it's necessary to understand the concept of homeostasis. "Homeo" meaning similar, and "stasis" meaning stable comes from the Greek words. Homeostasis is the body's ability to keep maintaining a stable environment internally, in spite of the changes that take place externally. Homeostasis occurs constantly in our bodies regardless of our activities and behavior throughout the day. For example, if we drink a lot of water we do not swell up, likewise, when we drink too little of water we don't shrivel. Our bodies know how much fluid we need to maintain at a constant level. However, if the positive and negative feedback loops are affected a homeostasis imbalance can occur, resulting in severe diseases, and sometimes even death. For example, diabetes, which is highly common, as well as fever. A few other examples include Graves disease, Cardiovascular disease, and Renal failure. Diabetes is a disease that can occur when there is an abnormally high level of blood glucose. Diabetes results when the body cannot maintain the blood sugar level in homeostatic balance. Blood glucose is increased, but the lack of insulin basically means that the sugar levels are not able to return to normal. If homeostasis is not restored, the high levels of blood sugar can damage blood …show more content…

The average body temperature usually ranges from 36.1 degrees Celsius to 37.8 degrees Celsius. When the body's homeostasis fails to control the body temperature around the thermoneutral zone, it could lead to hyperthermia. Hyperthermia is an abnormally high body temperature. If the body fails to lower the body temperature it could lead to heat stroke, and sometimes even death. When the body's temperature is abnormal you are likely to have a fever. Having a fever is a sign that something abnormal is going on in your

    As humans are homeothermic mammals, core temperature is maintained within a narrow range, usually within 0.2° of 37°C regardless of the environment. This is a life saving adaptation since various physiological systems in the body require narrow temperature ranges in which they can function optimally.

  • Diabetes

    992 Words  | 2 Pages

    Diabetes is a disease that causes an abnormally high level of sugar, or glucose, to build up in the blood. Glucose comes from food we consume and also from our liver and muscles. Blood delivers glucose to all the cells in the body. In people without diabetes, the pancreas makes a chemical called insulin which is released into the blood stream. Insulin helps the glucose from the food get into cells. When the pancreas doesn’t make insulin, it can’t get into the cells and the insulin stays in the blood stream. The blood glucose level gets very high, causing the person to have type one diabetes.

    2004 Words  | 5 Pages

    Homeostasis is the biological process that maintains a stable internal environment despite what occurs in the external environment. Chemicals and bodily functions are maintained in a balanced state so the body may function optimally. There are various systems in the human body that require maintenance through the processes of biochemical checks and balances so they may function properly. One of these systems includes the rise and fall of blood glucose and is under the control of the homeostatic regulation process. Homeostasis is essential in blood glucose regulation as high blood glucose levels (hyperglycaemia) and low blood glucose levels (hypoglycaemia) are dangerous and can affect the human body in many ways and can also lead

  • The Pathophysiology of Diabetes Mellitus.

    1147 Words  | 3 Pages

    The pathophysiology of diabetes mellitus in is related to the insulin hormone. Insulin is secreted by cells in the pancreas and is responsible for regulating the level of glucose in the bloodstream. It also aids the body in breaking down the glucose to be used as energy. When someone suffers from diabetes, however, the body does not break down the glucose in the blood as a result of abnormal insulin metabolism. When there are elevated levels of glucose in the blood, it is known as hyperglycemia. If the levels continue to remain high over an extended period of time, damage can be done to the kidneys, cardiovascular systems; you can get eye disorders, or even cause nerve damage. When the glucose levels are low in one’s body, it is called hypoglycemia. A person begins to feel very jittery, and possibly dizzy. If that occurs over a period of time, the person can possibly faint. Diabetes mellitus occurs in three different forms - type 1, type 2, and gestational.

    In our body’s we have thousands upon thousands of cells that work together to maintain the whole structure. Although cells accomplish different roles, they all are comparable in their metabolic conditions. Preserving a continuous inner environment with what the cells require to survive like sugar, minerals, oxygen and waste removal is essential for the cells and host well-being. The diverse process that the body controls its inner environment are referred to as homeostasis. Homeostasis refers to maintaining a stable environment in reaction to environmental changes. The body’s inner environment requires constant observation to maintain a stable inner environment this way if conditions occur they can be adjusted. Homeostatic regulation is the adjustment of systems in the body. “Homeostatic regulation involves three parts or mechanisms: 1) the receptor, 2) the control center and 3) the effector.” (Wikibooks, para. 2)

When a person has diabetes there are two ways it can affect the pancreas because there are two types of the disease. Type-1 diabetes affects the pancreas by not allowing the body to produce enough insulin to keep the body’s blood sugar at a healthy number. The opposite is for Type-2 which produces too much insulin and gives the body too much insulin keeping the blood sugar number above healthy (Type-2).

Cherif et al., (2010) state, the body depends on the precise action of each organ to maintain physical, mental, and emotional health of a human being. Also, homeostasis, the regulatory of body temperature plays a survival role in maintaining body functions. The integumentary system (skin) is the largest, and the most important part of the body. The skin is just one of the organ systems that will be discussed (Thibodeau & Patton, 2008). The body is expected to perform specific duties at specific times the organ systems as a whole, the most important organ system the integumentary system, and homeostasis, are what enables the body to perform on demand.
