Recommended: importance of homeostasis in human body

The homeostatic system works to create homeostasis within the body; this is the maintenance of the constant internal environment within a normal range of values. The homeostatic system consists of receptors, a control centre and effectors as shown by our model, these mechanisms work together in order to maintain a constant internal environment in order for the body to work as efficiently as possible. The negative feedback system is most commonly used when trying to achieve homeostasis and occurs when there is movement away from the normal. This triggers a mechanism to counteract the change. Negative feedback has a stabilising effect, returning internal conditions back to an ideal steady state. The receptors detect environmental stimuli that bring the homeostatic system away …show more content…

The excess glucose in the bloodstream is then absorbed by the cells within the liver where it is then converted into glycogen or fat in the liver which is then stored for times when blood glucose falls and is needed to run cells within the body. This whole system works by negative feedback in order to bring the blood glucose levels back towards the normal and create an ideal internal environment. Homeostasis is maintained constantly through the bodies every day activities when blood glucose levels fluctuate normally as you eat and then carry out low intensity activities. However behavioural factors can affect the blood glucose levels in the body in more dramatic ways which require the homeostatic system to work harder to regulate. One of the most common causes of low blood glucose is caused by prolonged physical activity; this can cause your blood glucose levels to drop for the next 24 hours following exercise. If blood glucose levels fall below 70mg/dl it is called hypoglycemia. When the body is put through prolonged lengths of

    While the respiratory and cardiovascular systems are most reliant on one another, all body systems require a functioning circulatory cycle in order to thrive. Blood circulation and consistent transfer of oxygen to cells is required to maintain cell and tissue life. Disturbances to this process will cause cells and tissues to die (Red Cross 48). This state of balance and functioning body systems is referred to as homeostasis, defined as a “condition of equilibrium in the body’s internal environment due to constant interaction of body’s many regulatory processes” (Tortura 8). Changes or disruptions to homeostasis are regulated by the Endocrine and Nervous systems of the body. The endocrine system is made up of glands placed throughout the body

    Our body obtains the energy by digesting the carbohydrates into glucose. Volumes of glucose are required by the body to create ATP. ATP is short for 'Adenosine Triphosphate ' and is an energy carrier. When we consume too many carbohydrates our body produces a lot of glucose and as a result blood glucose levels rise and sometimes they may rise over the normal range of blood glucose concentration. To bring it back within the healthy range, the homeostatic system of blood glucose regulation is used. The blood flows through the pancreas where the beta cells, receptors, detect the high blood glucose level. To counteract this stimuli beta cells alert the control centre, which are also the beta cells located in the islets of Langerhans in the pancreas. The secretion of insulin has to be done quickly but can only be carried out when insulin gene is switched on. Turning on the insulin gene switch can take 30 minutes to an hour therefore, the production of insulin by beta cells are done in advance and are packaged in vesicles right until blood glucose rises. Glucose comes into the beta cell to trigger the vesicle that contains the insulin to move towards the plasma membrane and fuse. This releases the insulin into the bloodstream where they are distributed throughout the body and only affect specific target cells. The receptor, a protein, on the target cell’s plasma membrane recognises and connects

  • 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)

  • Absorptive and Postabsorptive States

    The postabsorptive state is the period when the GI tract is empty and energy comes from the breakdpwn of our body’s reserves. The importance of the postabsorptive state is to maintain blood glucose levels. The brain fuels itself using glucose as its energy source. We can get glucose from stored glycogen, tissue proteins, and some from fats. The first available store of glucose is in the liver’s stores of glycogen. These stores can maintain blood sugar levels for around four hours. When the liver stores begin to get small, glycogenolysis begins to take place in skeletal muscles. The glucose in the skeletal muscles is converted to pyruvic acid, which enters the blood and is converted back to glucose by the liver and again reenters the blood.

    The immune system has the important job of protecting the body from foreign invaders. It is made up of a network of cells (including white blood cells), tissue and organs. The foreign invaders the immune system fight include viruses, bacteria, microbes and pathogens. In order to stop these foreign invaders, there is a process known as immune response that attacks in three different lines of defence. Without this immune response, the body would be constantly under invasion by pathogens trying to attack and induce illness.

    For people with no problems the intestines and stomach digest the carbohydrates that we take in into glucose, which is the body’s main source of energy. After we digest our food the glucose moves to the bloodstream. To get the glucose out of your blood and into the cells of your body the pancreas makes a hormone called insulin (Mayo Clinic, 2010). When you have gestational diabetes either your body does not make enough insulin during your pregna...

    When the blood glucose is higher than the normal levels, this is known as diabetes disease. The body turns the food we eat into glucose or sugar and use it for energy. The insulin is a hormone created by the pancreas to help the glucose get into the cells. The sugar builds up in the blood because either the body doesn’t make enough insulin or can’t well use its own insulin (CDC, 2015). In the United States diabetes is known as the seventh leading cause of death. There are different types of diabetes. However, there are two main types of diabetes and these are; Diabetes type 1 and Diabetes type 2 (CDC, 2015).

    When the blood sugar levels aren’t normal, it’s a disease called diabetes. Diabetes (diabetes mellitus) is a deficiency of the hormone insulin or the inhibition of its action with the cells. The insulin acts like a bridge between the glucose and the cells. In the US there are about 16 million people who suffer from diabetes. It is the seventh most common cause of all deaths. Diabetes is most common in Native American females over 45 years of age.

    The pancreas uses these two hormones in order to monitor blood glucose levels. After a meal, blood glucose usually rises. This is when insulin secretion will start (Nussey S, Whitehead S. “Endocrinology: An Integrated Approach”). Consequently, blood glucose decrease to the normal range. This is how insulin maintains blood levels when is high. However, when blood level falls below normal range, glucagon comes into play. Low blood glucose occurs usually when hungry and during exercise. This will then triggers glucagon secretion. When blood level falls, the body goes into imbalance. Hence is why in order to maintain homeostasis glucagon is crucial. The body will tell the pancreas to increase more glucose and the pancreas will secrete glucagon by taking glycogen from the liver to produce glucose. The glucose will produce energy and will make blood glucose concentration increase (Homeostasis of Insulin and Glucose, Abpischools.org). When the pancreas cannot maintain homeostasis, many problems will arise in the body. When the pancreas fails to produce insulin, type 1 and 2 diabetes can occur. For those with type 1 diabetes, insulin injections will be needed in order to regulate blood glucose level, otherwise, glucose levels will be out of control. For type 2 diabetes, they are not insulin dependent like type 1, however, the body does not create enough in the body. When blood glucose
