So notice along the border of our villas we basically have many, many of these intestinal cells we call anterocytes. And each one of these interasides contains tiny hairlike projections known as microvilli. So the villi and the microvilli, what the purpose of these structures are, is to basically greatly increase the surface area of the small intestine. And that basically means the proteolytic enzymes have more room to actually break down those macromolecules. Now, once we break down the macromolecules, they are absorbed by these intercepts and then they move into either the blood system, shown in red or the lymph system, shown in orange. So this single orange vessel is known as the lactile.
