Insulin is secreted by which organ?

Insulin is a hormone that plays a crucial role in glucose metabolism and is secreted by the pancreas. The pancreas is located behind the stomach and is an essential organ in the digestive system as well as in regulating blood sugar levels.

When blood sugar levels rise, such as after eating a meal, the pancreas detects this increase and responds by releasing insulin into the bloodstream. Insulin then facilitates the uptake of glucose by cells, allowing them to use glucose for energy or store it for future use. This process helps maintain balanced blood sugar levels, which is vital for overall health.

Understanding the role of the pancreas in insulin secretion is important, especially in the context of conditions like diabetes, where insulin regulation is impaired.
