The lacteals of the intestinal villi are part of the lymphatic system and are responsible for absorbing

  • A. glucose
  • B. amino acids
  • C. water and mineral ions
  • D. the products of fat digestion

Explanation

Fatty acids and glycerol are reassembled into fats inside the villus cells and packaged into droplets too large for the blood capillaries, so they enter the lacteal instead and reach the blood later at the thoracic duct. Glucose and amino acids are water soluble and pass directly into the blood capillaries of the villus. This is why a lymph sample after a fatty meal looks milky.
