What is the passage of digested food from the digestive tract into the cardiovascular system?

Answer 1

The term you are looking for is "absorption." Absorption is the process by which digested molecules and compounds, pass through the epithelial layer (the skin cells that line the inside of the digestive tract, as well as many other parts of the body) and into the circulatory system or, in the case of fats, the lymphatic system.

Answer 2

Absorption of food particles from the digestive organs into the blood occurs with the help of many transporter proteins the apical and basal membrane of the epithelial cells lining the digestive tract. Most of the food ingested is broken down into monomer molecules because otherwise those molecules are just too big to be absorbed. Several enzymes participate in breakdown of food particles in our digestive system.

edit: The food which gets digested in the stomach moves to the small intestine which is where the absorption of nutrients takes place. As the undigested material moves into the large intestine it is still absorbing nutrients. The large intestine absorbes the liquids that are left.

The pharynx
