The stomach, as part of the larger gastrointestinal tract, contains a variety of hormones that regulate digestion and appetite. The gut is actually the largest endocrine organ in the body, containing over 50 gut hormone genes. Here are some key hormones found in the stomach:
- Gastrin: Is one of the first discovered gut hormones.
Key Stomach Hormones
The following table outlines some of the major hormones found in the stomach and their functions:
Hormone | Function |
---|---|
Gastrin | Stimulates the secretion of hydrochloric acid (HCl) and pepsinogen, which are essential for breaking down food in the stomach. It also promotes gastric motility. |
Secretin | Is one of the first discovered gut hormones. Stimulates the pancreas to release bicarbonate to neutralize stomach acid entering the small intestine. |
Cholecystokinin (CCK) | Is one of the first discovered gut hormones. Stimulates the release of digestive enzymes from the pancreas and bile from the gallbladder; also acts as a satiety signal. |
It's important to remember that the gut is a complex endocrine system, and many other bioactive peptides play roles in regulating digestion, appetite, and overall gastrointestinal function.
