Fats. Fat molecules are a rich source of energy for the body. The first step in digestion of a fat such as butter is to dissolve it into the watery content of the intestinal cavity. The bile acids produced by the liver act as natural detergents to dissolve fat in water and allow the enzymes to break the large fat molecules into smaller molecules, some of which are fatty acids and cholesterol. The bile acids combine with the fatty acids and cholesterol and help these molecules to move into the cells of the mucosa. In these cells the small molecules are formed back into large molecules, most of which pass into vessels (called lymphatics) near the intestine. These small vessels carry the reformed fat to the veins of the chest, and the blood carries the fat to storage depots in different parts of the body.

carbohydrates
lymphatic
The digestive system prepares food for the bloodstream. The digestive system absorbs food particles and nutrients pass through this system to the bloodstream.
Digestion
lipase helps to absorbs fat in your bloodstream
Simple sugars are considered carbohydrates, like starches are, and effects the blood sugar. The circulatory system is responsible for transporting the sugar through the body, first out of the digestive tract and then into the cells.
bile
The small intestine. It has villi that absorb nutrients and then transport them to the bloodstream.
digestive system.
Large intestine
the small intestine
digested food goes to the bloodstream before any where else.
Small intestine
The stomach, small intestine, and large intestine are the digestive organs responsible for absorbing nutrients.
