The digestive system breaks down the food we eat into small parts so our body can use the nutrients for energy and growth.

Digestion starts in the mouth where food is chewed and mixed with saliva, which contains enzymes to begin breaking down food.

The chewed food moves down the oesophagus (food pipe) into the stomach.

In the stomach, food is mixed with stomach acids and digestive juices that break it down further and kill bacteria.

The food then enters the small intestine, where it is mixed with bile from the liver and enzymes from the pancreas to digest proteins, fats, and carbohydrates.

The inner walls of the small intestine have villi, tiny finger-like projections that absorb nutrients into the bloodstream.

Undigested food passes into the large intestine, where water and salts are absorbed.

Waste materials are pushed out of the body through the anus as feces.
