What organ contains alpha and beta cells that secrete hormones into the bloodstream?

The pancreas is the organ that contains alpha and beta cells, which play crucial roles in regulating blood sugar levels. Alpha cells produce glucagon, a hormone that raises blood glucose levels by promoting the conversion of glycogen to glucose in the liver. On the other hand, beta cells produce insulin, which helps lower blood glucose levels by facilitating the uptake of glucose by cells for energy use or storage as glycogen.

This coordinated release of hormones by the pancreas is vital for maintaining homeostasis in the body's metabolism, especially in response to food intake and energy needs. Without the proper functioning of these cells, conditions such as diabetes can occur, highlighting the importance of the pancreas in endocrine regulation.
