Digestive System


Main function of the system

Your digestive system provides the nutrients your cells need to produce energy.

Main parts of the system

salivary glands, esophagus, liver, stomach, gall bladder, small intestine, and large intestine

What each part does

Your salivary glands create saliva, your esophagus transports food to your stomach, your liver produces bile, gastric juice produced by stomach contains acid and chemicals that breaks down proteins, your gall bladder stores the bile which is made by the liver, nutrients diffuse through the villi projections sticking out of the walls of the small intestine, from the small intestine undigested food passes into the large intestine.

How does this system affect other body systems

The digestive system transports the nutrients into the blood. Then the circulatory system transports them to your cells.
