The organ responsible for producing insulin is the pancreas. This glandular organ is located behind the stomach and plays a crucial role in both the digestive and endocrine systems. Insulin is a hormone that regulates blood sugar levels in the body by facilitating the uptake of glucose into cells. Dysfunction in insulin production can lead to diabetes, a condition characterized by high blood sugar levels. The pancreas contains clusters of cells known as the islets of Langerhans, where insulin-producing beta cells are found. Maintaining healthy pancreas function is essential for overall metabolic health.
