Pancreozymin is a hormone produced by the small intestine in response to the presence of fats and proteins in the digestive tract. It plays a crucial role in stimulating the pancreas to release digestive enzymes, which help break down food for better absorption. Additionally, Pancreozymin promotes the secretion of bile from the gallbladder, aiding in the digestion of fats. This hormone is essential for maintaining proper digestive function and ensuring that nutrients are effectively utilized by the body.
