Blood Sugar Regulation

Blood sugar, also known as blood glucose, is the primary source of energy for the body's cells. It is important for the body to regulate blood sugar levels to ensure that they remain within a healthy range. The regulation of blood sugar is primarily controlled by the hormones insulin and glucagon, as well as the liver and muscles.

Insulin

Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels. When blood sugar levels are high, such as after a meal, the pancreas releases insulin into the bloodstream. Insulin helps the body's cells absorb glucose from the bloodstream, which lowers blood sugar levels.

Glucagon

On the other hand, when blood sugar levels are low, the pancreas releases another hormone called glucagon. Glucagon signals the liver to release stored glucose into the bloodstream, thereby raising blood sugar levels.

Liver and Muscles

The liver and muscles play a critical role in regulating blood sugar levels. The liver stores glucose in the form of glycogen and can release it into the bloodstream when blood sugar levels are low. Muscles also store glycogen and can take up glucose from the bloodstream when needed for energy.
