Homeostasis - blood sugar and temperature.
In blood glucose regulation the levels of glucose in the blood are detected by the alpha and beta cells within islet cells, the islet cells can be located in the pancreas. The pancreas is a glandular organ which works as the control centre of blood glucose regulation in the body. It controls the homeostasis of glucose in the blood by monitoring the stimuli a.
Explain the concept homeostasis with reference to the control of heart rate, breathing rate, body temperature and blood glucose. In this assignment I will be introducing a formal report that is based on an investigation into how the body responds to exercise and which analyses the results from the investigation. The investigation involves myself and other pupils in my class. I will be doing.
Glucose Homeostasis and Starvation. Glucose Homeostasis: the balance of insulin and glucagon to maintain blood glucose. Insulin: secreted by the pancreas in response to elevated blood glucose following a meal. Insulin lowers blood glucose by increasing glucose uptake in muscle and adipose tissue and by promoting glycolysis and glycogenesis in liver and muscle.
The control and maintenance of blood sugar levels is an example of homeostatic regulation by the endocrine system. Blood sugar is maintained by two hormones secreted by the pancreas: insulin and glucagon. Blood sugar rises after digestion of food. In response, pancreas cells are stimulated to secrete insulin, which enables sugar uptake by cells and the storage of sugar in the liver and muscles.
After you have eaten a meal, the blood glucose levels will begin to rise because the carbohydrates in the food are digested and absorbed. This rise is detected by beta cells, which then will produce more insulin.This insulin then binds to receptor proteins in cell membranes (particularly in the liver).This causes more protein channels to open so that more glucose can enter the cell.
Homeostasis is the maintenance of a constant internal environment. Examples of homeostasis and negative feedback include the regulation of blood sugar level and the regulation of body temperature. Diabetes and lack of blood sugar regulation.
Glucose is an important energy source used by most cells in the body, especially muscles. Without glucose, the body “starves”, but if there is too much glucose, problems occur in the kidneys, eyes, and even with the immune response. Insulin is a hormone produced by the pancreas in response to increased blood glucose levels. When the.
