Describe the physiological process that takes place in small intestine?

Explanation: Contractions move food through your small intestine. After you eat a meal, your small intestine contracts in a random, unsynchronized manner. Food moves back and forth and mixes with digestive juices. Then stronger, wave-like contractions push the food farther down your digestive system. These movements are known as peristalsis. Your enteric nervous system controls the movements in your small intestine. This is a network of nerves that runs from your esophagus to your anus.

After food leaves your small intestine, contractions push any food that remains in your digestive tract into your large intestine. Water, minerals, and any nutrients are then absorbed from your food. The leftover waste is changed into a bowel movement.
