Blood sugar regulation cells in the pancreatic islets are among the most well understood and important. If the blood glucose level falls to dangerous levels (as during very heavy exercise or lack of food for extended periods), the alpha cells of the pancreas release glucagon, a hormone whose effects on liver cells act to increase blood glucose levels. They convert glycogen into glucose (this process is called glycogenolysis). The glucose is released into the bloodstream, increasing blood sugar. Hypoglycemia, the state of having low blood sugar, is treated by restoring the blood glucose level to normal by the ingestion or administration of dextrose
Organ procurement like organ theft or organ trade, fair organ distribution, and to a lesser degree, animal rights and religious prohibition on consuming some animals such as pork. There is a shortage of organs available for donation with many patients waiting on the transplant list for a donation match. About 20 patients die each day waiting for an organ on the transplant list. When an organ donor does arise, the transplant governing bodies must determine who receives the organ. The UNOS computer matching system finds a match for the organ based on a number of factors including blood type and other immune
