Which hormone is produced in the pancreas and released into the bloodstream when glucose levels rise?

The hormone produced in the pancreas and released into the bloodstream when glucose levels rise is insulin. Insulin plays a crucial role in regulating blood sugar levels, facilitating the uptake of glucose by cells for energy or storage as glycogen in the liver and muscles. When blood glucose levels increase, such as after eating, the pancreas responds by secreting insulin to help lower these levels back to normal. This process is essential for maintaining homeostasis in the body and preventing conditions like hyperglycemia, which is an excess of glucose in the bloodstream. Understanding the function of insulin is fundamental in fields such as medical administration, as it relates to managing diabetes and other metabolic conditions.
