And we'll discuss the function of this much more in much more detail when we'll discuss the blood clot cascade. Now, the final organ that I'd like to briefly discuss is the stomach. The stomach actually produces many different hormones and many different enzymes, as does our small intestine. And we'll discuss this in much more detail when we'll discuss our digestive system. In this lecture, I'd like to briefly mention that the stomach releases a peptide hormone known as gastrin. And gastroin is basically used to stimulate the secretion of hydrochloric acid, known as gastric acid, by the parietal cells of our stomach.
