Where are the Alpha and Beta cells of the Pancreas located and what are their functions in relation to blood glucose homeostasis?

Alpha and Beta cells are the two key cells used in blood glucose regulation in the body.Location = Islets of Langerhans (which are groups of cells located predominantly inside the tail of the pancreas)Beta cells:This cells main function is the endocrine process of insulin secretion Insulin is a hormone involved in the absorption of glucose into cells in the body (this is mainly muscle and fat (or adipose tissue)) when the bodies blood glucose is too high.Insulin also causes the storage of glucose in the body via a process called Glycogenesis (the formation of glycogen as seen below)Alpha cells:This cells main function is the endocrine process of glucagon secretionGlucagon is a hormone that is secreted when blood glucose levels are too low and they cause the break down of glycogen (glycogenolysis), a long chain insoluble polysaccharide that is stored in the liver Glucagon also causes gluconeogenesis, a process by which substances such as amino acids and triglycerides fuse to form glucose. This process also helps to increase blood glucose levels in absence of glycogen storage
