Osmosis video - Gastric motility

Gastric motility is the coordinated movement of the muscles and secretions of the stomach. This coordinated activity propels food and drink through the stomach and comprises three main phases. First, there is receptive relaxation characterized by the relaxation of lower esophageal sphincter, to let food pass through into the stomach. Next, there is secretion in which the gastric juice is released in the stomach, and peristalsis helps to mix contents and break apart food particles. Finally, there is gastric emptying which occurs when food leaves the stomach and goes into the duodenum.
