How does your body expel fat?

According to WebMD, fat in the body is digested by an enzyme called "lipase." Different lipase can be found in different parts of the body, and while they all break down fats, each type of lipase differs slightly in the way it functions.

WebMD states that the three different types of lipase are pharyngeal lipase, hepatic lipase and pancreatic lipase. Pharyngeal lipase is produced in the mouth in order to break down fats during digestion. Hepatic lipase is created in the liver to regulate the amount of fat in the blood. Pancreatic lipase is created in the pancreas to aid pharyngeal lipase during digestion.
