Blood glucose
Blood Glucose
Blood glucose (pronunciation: /blʌd 'gluːkoʊs/), also known as blood sugar, is a crucial biochemical substance that our bodies use for energy. It is derived from the food we eat and is carried to the cells through the bloodstream. The regulation of blood glucose levels is essential for proper body functioning.
Etymology
The term "blood glucose" is derived from the Greek word "glykys," which means sweet. This is in reference to the sweet taste of glucose. The term "blood" is derived from the Old English word "blod," which has been used in its current sense since the late 14th century.
Regulation of Blood Glucose
The regulation of blood glucose is primarily handled by two hormones: Insulin and Glucagon. Insulin is produced by the Pancreas when blood glucose levels are high, such as after a meal. It helps cells take in glucose from the bloodstream. Glucagon, on the other hand, is released when blood glucose levels are low, and it triggers the release of stored glucose from the liver.
