How digestion occurs in the stomach?

The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

There are four basic types of digestive systems: monogastric, avian, rumi- nant, and pseudo-ruminant. A monogastric digestive system has one simple stomach. The stomach secretes acid, result- ing in a low pH of 1.5 to 2.5. The low pH destroys most bacteria and begins to break down the feed materials.
