Homeostasis literally means “same state” and it refers to the process of keeping the internal body environment in a steady state‚ when the external environment is changed. The importance of this cannot be over-stressed‚ as it allows enzymes etc to be ‘fine-tuned’ to a particular set of conditions‚ and so to operate more efficiently. Much of the hormone system and autonomic nervous systems is dedicated to homeostasis‚ and their action is coordinated by the hypothalamus. In Module 2 we saw how

blood glucose values in an adult? Hypoglycemia: Low blood glucose level that results from too much insulin‚ not enough food‚ or excess activity. It is defined as the presence of Whipple’s triad: manifestations consistent with low blood glucose‚ a low plasma glucose concentration‚ and resolution of symptoms or signs after plasma glucose concentration is raised. Four common causes are: 1.) excess insulin‚ 2.) deficient intake or absorption of food‚ 3.) exercise‚ and 4.) alcohol intake. When blood glucose

Diabetes is a life-long disease with no known cure or vaccine‚ which is caused by the absence of insulin production‚ a decreased production level or the inability to use insulin properly. Insulin is a hormone produced in the pancreas and secreted by the cells located in the beta cells of the Islets of Langerhans. While the beta cells of the pancreas secrete insulin‚ glucagon is secreted by the alpha cells. Insulin regulates blood glucose levels to prevent an increased or an abnormally decreased amount of

in cases where there is a continuous rise in the amount of blood glucose levels. Diabetes can be insulin dependant diabetes mellitus (type 1) meaning that the patient has got no insulin production or type 2 which is non insulin dependant. Type 1 diabetes occurs in at an early age. Patients with this condition have poor or no insulin production therefore blood glucose levels are high. The lack of insulin production is usually caused by antibodies produced by the immune system. These antibodies begin

document to your instructor in your assignment box. 1. Endocrine System Question 1: How does the insulin and glucagon secreted by the pancreas function in glucose metabolism? Answer 1: Insulin and glucagon work together to keep glucose levels in the blood within the normal range. When there is an elevated blood glucose level‚ this stimulates beta cells in the pancreas to secrete insulin. The insulin facilitates the uptake of glucose by body cells‚ and the liver will uptake the glucose and stores

The Basic Mechanisms of Homeostasis Overview of homeostasis The term homeostasis was first coined by Walter Cannon in 1929 to literally mean ‘steady state’. It describes the dynamic equilibrium by which internal constancy is maintained within set limits by regulation and control. There are many examples of homeostatic control throughout the human body and in other living organisms‚ such as pH‚ pressure‚ and temperature. A concept important to homeostasis is the process of feedback circuits;
