The small intestine is where most digestion takes place. A pyloric sphincter controls the rate of flow of chyme from the stomach into the small intestine. Most digestion occurs in the upper portion of the small intestine, called the duodenum. Below the duodenum is the jejunum ,…

What are the body parts involved in the digestion?

Parts of the Digestive System Esophagus. The esophagus transfers food from the mouth to the stomach through peristaltic movements. The esophagus is a tubular organ that connects the mouth to the stomach. Stomach. A large part of digestion occurs in the stomach, shown in Figure 3. Small Intestine. Chyme moves from the stomach to the small intestine.
