Regulation of blood glucose in the human body
Cannon (1989) used the term homeostasis to describe the consistency of the internal environment and the regulatory integrated mechanisms are directed to maintain it. He also stated that it was how the system responded to an emergency by trying to meet the sudden external demands which have been placed upon the human body (1). Homeostasis is important within the human body because it maintains the optimum environment required for various processes to occur. The human body cells are able to acquire energy from lipids; however nerve cells (neurons) rely completely on glucose. Therefore, the regulation of blood glucose it is human body is necessary to ensure the functioning of the nervous system as well as allowing cellular respiration to occur. (2)
Glucose is an organic molecule will provide an energy source towards the metabolic activities of the human body. It is also a key source of carbon skeletons for biosynthesis. The energy stored with the glucose molecule is released via a process called glycolysis. Glycolysis occurs during respiration. When it is fully broken down, glucose is converted into adenosine triphosphate (ATP). This allows manageable amount of energy to be released to power the various biochemical reactions which occurs.
The two main hormones which are used to regulate the concentration of the blood glucose concentration are insulin and glucagon. In figure 1, it shows how the insulin and glucagon are able to regulate the blood glucose levels. Insulin decreases the blood glucose concentration while glucagon increases it; therefore they are known as the antagonistic hormones as they are opposites. If the blood glucose concentration is above 70-110mg/100mL, the beta cells ...

...r. This was then repeated after 60 minutes however during this time the participant would have consumed 600ml of water. One of the readings on the Urilux stick showed whether there was glucose present within the urine. The table below show the results collated from the class data.

3 Norm Norm
4 Norm Norm
5 Norm Norm

The results show that after the consumption of 600ml of water, the participants had the expected amount of glucose within their urine. This shows that none of the participants are undiagnosed / untreated diabetic. This can be induced because glucose was not found in the urine. Within diabetic, glucose would be present as the body is unable to utilize the glucose therefore removes it from its system as it is unable to retain it.

  • Why The Discovery of Insulin is a Defining Moment in Canadian History

    During the year 1889, two researchers, Joseph Von Mering and Oskar Minkowski, discovered the disease that is known today as diabetes. Diabetes is a disease in which the insulin levels (a hormone produced in unique cells called the islets of Langerhans found in the pancreas) in the bloodstream are irregular and therefore affect the way the body uses sugars, as well as other nutrients. Up until the 1920’s, it was known that being diagnosed with diabetes was a death sentence which usually affected “children and adults under 30.” Those who were diagnosed were usually very hungry and thirsty, which are two of the symptoms associated with diabetes. However, no matter how much they ate, their bodies wouldn’t be able to use the nutrients due to the lack of insulin.

    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)

    Other hormones (glucagons, epinephrine, growth hormone, and cortisol) work to oppose the effects of insulin and are often referred to as counterregulatory hormones. These hormones work to increase blood glucose levels by stimulating glucose production and output by the liver and by decreasing the movement of glucose into the cells. Insulin and the these counterregulatory hormones provide a sustained but regulated release of glucose for energy during food intake and periods of fasting and usually maintain blood glucose levels within the normal range. An abnormal production of any or all of these hormones may be present in diabetes.

    Diabetes refers to a set of several different diseases. It is a serious health problem throughout the world and fourth leading cause of death by disease in the country. All types of diabetes result in too much sugar, or glucos in the blood. To understand why this happens it would helpful if we understand how the body usually works. When we eat, our body breaks down the food into simpler forms such as glucose. The glucose goes into the bloodstream, where it then travels to all the cells in your body. The cells use the glucose for energy. Insulin, a hormone made by the pancreas, helps move the glucose from bloodstream to the cells. The pathophysiology of diabetes mellitus further explains the concept on how this disease works. Pancreas plays an important role of the metabolism of glucose by means of secreting the hormones insulin and glucagon. These hormones where then secreted by Islets of Langerhans directly to the blood. Inadequate secretion of insulin results on impaired metabolism of glucose, carbohydrates, proteins and fats which then result to hyperglycemia and glycosuria. Hyperglycemia is the most frequently observed sign of diabetes and is considered the etiologic source of diabetic complications both in the body and in the eye. On the other hand, glucagon is the hormone that opposes the act of insulin. It is secreted when blood glucose levels fall.

    Glucose is a sugar that plays a big part in a human’s health and well-being. This sugar is a major source of energy for the body’s brain and cells. The Cells that receive energy from glucose help in the building of the body’s muscle and tissue. Although glucose may be important to the body too much of this sugar can cause a chronic condition called Diabetes. Diabetes, also known as Diabetes mellitus, is a chronic condition that is caused by too much sugar in the blood. This condition can affect all age groups. In fact, in 2010 a survey was taken by the National Diabetes Information Clearinghouse, on the number of newly diagnosed diabetes. Out of 1,907,000 people: 24.38% were ages 20-44, 55.17% were ages 45-64, and 20.45% were ages 65 and greater. Diabetes is a very serious condition, and it can be deadly if left untreated. This paper will help better educate the reader on the signs and symptoms, the testing process, and the management of diabetes.

    Diabetes Mellitus is a disease in which the pancreas produces little or no insulin. Insulin is a hormone that helps the body’s tissues absorb glucose which is sugar, so it can be used as a source of energy. Glucose levels build up in the blood and urine which causes excessive urination, thirst, hunger, and problems with fat and protein metabolism in a diabetic person. Diabetes is very common in the United States; it is the seventh leading cause of all deaths. Women have been diagnosed with diabetes more than men. There are two forms of diabetes, Type one and Type two diabetes. Type one diabetes is when the body does not produce insulin or produces it in very small quantities. This usually occurs in younger people under twenty years of age, mostly around puberty. Type two diabetes is when the body’s balance between insulin production and the ability of cells to use insulin doesn’t work properly. This is more common than type one; about 90-95% people in the United States have it. There are no cures for diabetes now but there are many researchers investigating factors through new technologies to cure them. Meanwhile, technological advancements are being made to keep glucose at a good level for diabetes.

    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
