The Digestive System

We need food to gain energy in the body so that it is possible to live. Food stores nutrients that the digestive system breaks down and transport it to the organs in the body. The digestive system is a process that breaks down food mechanically and chemically to give the cells in the body nourishment.
Foodfirst has to get digested mechanically. When food is put into the mouth, the teeth bites off and chew food into the soft pulp that is easy to swallow. Then the salivary gland makes the food moist and slippery. The esophagus takes food from the throat and pushes it downthrough the stomach. It moves food by the way of contraction. Then the stomach mashes the food into a sloppy soup and starts to attack the food chemically with enzymes by breaking down and dissolving its nutrients.
The food chemically digest with the help of enzymes. After the food goes the stomach it enters the pancreas. The pancreas makes powerful digestive juices called enzymesto help the food digest as it enters the small intestines. In the small intestines, enzymes continue the chemical attack on the food, until the nutrients are small enough to pass through the lining of the small intestine and into the blood, in which they get stored and distributed in parts of the body, such as the liver. The liver stores some nutrients, changes them from one form to another, and releases them into the blood according to the activities and needs of the body. After the food enters the small intestines it goes into the large intestines. The large intestines absorb any useful substances in the leftovers, such as spare water and body minerals back into the blood. The remains form semi-solid faeces, ready to be removed from the body. The rectum stores faeces that are squeezed through a ring of muscle called the anus, and out of the body, ending the digestion.
