In the digestive tract, food is liquefied primarily by saliva in the mouth, gastric juices in the stomach, and digestive enzymes and bile in the small intestine. Saliva contains enzymes like amylase that begin breaking down carbohydrates. Once food reaches the stomach, gastric acid and pepsin further break down proteins, while bile emulsifies fats in the small intestine, allowing for easier digestion and nutrient absorption.
The Digestive Tract
The action that forces food into the digestive tract is swallowing. This begins with the tongue after mastication (chewing).
PeristalsisPeristalsis
Peristalsis is the process that propels food through the digestive tract. It involves rhythmic contractions of the muscles in the gastrointestinal tract that push food and nutrients along the digestive system.
The food is passed through the digestive tract when the worm moves. The movement causes the muscles to contract and move the food through the system.
By the swallowing reflex.
The movement of food through the digestive tract is regulated by muscles. Muscles produce a narrowing which pushes the food through each of the digestive organs until it reaches the entrance of the stomach.
Fiber is the nutrient that helps move food through the digestive tract. It provides bulk, which activates the stretch receptors in the muscles of the digestive tract, stimulating them to activity.
Food moves through the digestive tract.
Propulsion is the movement of food down the esophagus and peristalsis is the contractions in the stomach walls that moves food through the digestive tract.
