Each villus holds a lymphatic capillary called a lacteal. What does the lacteal take up?

ALipid breakdown products
BSugars released from starch
CAmino acids from proteins
DWater and dissolved salts
Answer & Solution
Correct answer: A. Lipid breakdown products
1. Each villus contains a capillary bed of one arteriole and one venule plus a lacteal. 2. The capillary bed takes up the water-soluble breakdown products, the sugars and amino acids. 3. The lacteal takes up lipid breakdown products and passes them to the lymphatic system. 4. Those lipids reach the bloodstream only after travelling through lymphatic vessels. 5. Water and salts are absorbed across the epithelium into blood, not into the lacteal. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 23 "The Digestive System", section 23.5 The Small and Large Intestines_
