Fats go through many stages of the human body from the mouth to the small intestine. Obviously for fat to be in the body it has to be consumed through the mouth.Consuming fats begins when the food enters the mouth, the mouth breaks down the food and the saliva softens the food so it can be swallowed. The food travels down the esophagus and multiple muscles in the esophagus move the food down into the stomach. Then the food gets digested in the stomach chamber and the nutrients go to the small intestine. The small intestine has enzymes called lipase which break down fats into fatty acids and glycerol. Before the lipase break down the fats the liver produces bile. Then after the fat has been broken down the fat is stored in cells called adipocytes.The main purpose of adipocytes cells is to store fat under the human skin.
