The Effect Of Glucose On The Body

When the blood glucose levels rise above the optimum, the pancreas detects this, and sends a metabolic signal for the pancreas to produce insulin in the beta cells. The beta cells are a part of a cluster of cells called the Islets of Langerhan. The hormone insulin is made here because the pancreas is a part of the endocrine system. (4) Insulin helps our cells convert glucose into energy, and it helps our bodies store extra glucose for use later. Insulin does this by turning the extra food into larger packages of glucose called glycogen. Glycogen is stored in the liver and muscles. When the body consumes food the pancreas will produce more insulin than normal as more is needed, and less insulin when it is not needed as much. (7)

The hypothalamus will send a signal to the pancreas to release glucagon, the hormone responsible for increasing glucose, to the blood. After glucagon enters the blood it will go to the target cell to bind to the receptor. After it reaches the receptor, glucagon stimulates the breakdown of glycogen, which will then secrete glucose to the blood thus increasing the blood glucose levels. This is an example of positive feedback. Once the receptors in blood detect that the glucose in the blood is increasing, the target cells will then send a signal to the to stop the stimulation of glucagon. This is called negative

The body must keep a healthy blood glucose level so that there is a continuous supply of energy to the cells. If the blood sugar levels fall too low (hypoglycaemia) it can cause harmful complications such as fatigue and even loss of consciousness. If blood sugar levels raise too high (hyperglycaemia) it can lead to many difficulties such as cardiovascular disease, nerve damage and kidney damage (S Preet, 2013). This is why is important for the body to regulate its glucose levels. It does this by the pancreatic islets detecting a change in blood glucose levels, they then release the hormone insulin into the blood stream. Muscle cells are prompted by the insulin, to absorb glucose. The way insulin does this is by binding itself to receptors on the cell membrane, thuds increasing the amount of transporters and allowing more glucose to be transported into the cells. If glucose levels fall then another hormone is released by the pancreas called glucagon. Glucagon allows stored glucose (glycogen) to be released from the liver into the blood stream and raises blood glucose levels (Amis, 2011). This process of keeping blood glucose levels constant is an example of ‘homoeostatic control’ where the rise and fall of glucose levels allows each different hormone to be used in a constant

The body regulates the blood glucose levels by producing insulin. Insulin is a chemical messenger essential for the entry of glucose into a cell. When the pancreas fails to produce insulin that is sufficient to use, the level of glucose in the blood will remain high. If to much insulin is produced, or given through medication, the level of glucose in the blood will remain low. In type 2 diabetes the cells become resistant to insulin and ignore its message to be absorbed into the cells, this is known as insulin resistance. Insulin deficit results in decreased transportation of glucose from cells in the body, hyperglycemia then arises causing to much glucose to be present in the bloodstream (Gould and Dyer, 2011: 550). The pancreas is located

The hormone which is made by the pancreas is said to be insulin that permits the body to utilize sugar from carbohydrates and its maintain energy for future use. Insulin mainly helps to maintain the sugar level in blood from getting high to low. The cells in the body require energy which can get from sugar and it cannot go directly into the cells. After eating the food, blood sugar level increases that time the cells in the pancreas will give signal to release insulin in the blood stream. Insulin after attaches to and the cell in signal will absorb sugar in the bloodstream. Insulin is termed as key which open the cell to allow the sugar into the cell and it can be used for energy.

Every human body wants to maintain blood glucose (blood sugar) level in normal range (70-100mg/dl). After we eat, the stomach digest food breaking it down into type of sugar, called glucose. Furthermore, this glucose is released into the bloodstream (Figure 1). The rise of glucose level triggers the pancreas, one of the body’s organ, to release insulin, a hormone, it blood stream.

A disruption in which blood glucose levels may be affected is when someone goes through starvation. The body needs a constant supply of glucose in order for the body to function properly as it is used for energy, so when someone goes through starvation the body won’t have a supply of glucose.

Glucose is the main response of the sympathetic nervous system is to activate the endocrine system to produce a chemical called adrenalin. Adrenalin travels around the body in the bloodstream and causes many other responses, including increased heart rate and blood pressure, and the released of stored glucose into the bloodstream. Adrenalin floods into your system, causing an increase in the strength and rate of the heartbeat, raising your blood pressure and speeding up the conversion of glycogen into glucose, which provides energy to the muscle.

Blood glucose is important as it is the ‘fuel’ that powers all cellular processes in our body. However the amount of glucose in our blood must be maintained carefully, the body must do this to ensure Homeostasis is maintained in response to external and internal environmental fluctuations. Homeostasis is the process through which bodily functions and chemicals are kept in a state of balance (stasis) allowing the body to function optimally. The mechanism that detects the changes in the internal environment away from the normal and acts to return it to a steady state is negative feedback. Negative Feedback has three functional components; a receptor, a control centre and an effector, each of these components work together to respond to fluctuations

Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the pancreas. Insulin lowers the blood glucose level. When the blood glucose elevates insulin is released from the pancreas to normalize the glucose level by promoting the uptake of glucose into the body cells. Diabetes is chronic medical condition, meaning that although it can be controlled, it lasts a

Glucose acts as an energy source for cellular functions and it comes from carbohydrates in the food we eat. Our body regulates glucose levels with a hormone called insulin. Insulin, which is produced in within the pancreas, is critical in providing balance within in our body by transporting glucose to cells. When excess glucose resides within the blood, condition known as hyperglycemia, the body’s nature course of action is to release insulin. Insulin will then transport excess glucose to the liver for storage and use it when it’s needed for hypoglycemia, low blood sugar. When the body cannot properly balance its own glucose levels, this leads to a condition called Diabetes Mellitus (DM). DM is classified into two types, Type 1 is where

A hormone made and released by the pancreas that regulates the levels of glucose present in the bloodstream by moving from the pancreas and opening the body cells to let glucose in for energy.

The purpose of blood glucose regulation is to maintain the levels of blood sugar in the body at homeostasis. As humans, our bodies rely on our blood glucose levels to be maintained within a very small range (approximately between 5mM and 10mM). It is important for blood glucose levels to remain stable and within these approximate boundaries because the brain and body struggle to function properly outside of this range. Insulin and Glucagon are both pancreatic endocrine hormones secreted from the pancreas in order to maintain homeostasis in blood glucose regulation. It is the production of these hormones that is necessary in humans in order to prevent diseases such as diabetes or hypoglycemia from developing.
