What hormone does the pancreas release to control blood levels?

The pancreas is a critical organ in the regulation of blood sugar levels, primarily through the secretion of the hormone insulin. Insulin is released in response to elevated blood glucose levels, such as after a meal. Its primary role is to facilitate the uptake of glucose into the cells, where it can be used for energy or stored for later use. This process lowers the amount of glucose in the bloodstream, helping to maintain stable blood sugar levels, which is crucial for overall metabolic health.

Understanding insulin's role is essential in nutrition and fitness, as imbalances in insulin production can lead to conditions such as hypoglycemia or hyperglycemia, which can significantly impact a person's energy levels and overall health. Other hormones listed, like cortisol and adrenaline, are involved in different metabolic processes and responses to stress, while glucose itself is not a hormone but rather a simple sugar and an important energy source for the body.
