What organ in the human body produces insulin?

The pancreas is the organ responsible for producing insulin in the human body. Insulin is a crucial hormone that regulates blood sugar levels by facilitating the uptake of glucose into cells for energy or storage. The pancreas contains clusters of cells called the islets of Langerhans, which specifically produce insulin.

When blood sugar levels rise after eating, the pancreas senses this increase and releases the appropriate amount of insulin to help lower blood glucose levels back to a normal range. This function of the pancreas is essential for maintaining metabolic equilibrium and energy balance in the body. If insulin production is inadequate or if the body's cells become resistant to insulin, conditions such as diabetes can develop, highlighting the importance of the pancreas in glucose regulation.
