Which structure is responsible for absorbing fatty acids from the gut?
A
Epithelial cells
B
Protein pumps
C
Network of capillaries
D
Lacteal
Explanation: 

Detailed explanation-1: -Answer and Explanation: The lacteal is the structure that helps with fat absorption. Lacteals are lymphatic vessels in the small intestine that absorb dietary fats. Dietary fats are insoluble and thus form aggregates with transport proteins.

Detailed explanation-2: -Lacteals are lymphatic vessels found in small intestinal villi. While other nutrients such as amino acids and saccharides are absorbed into the blood stream, lacteals absorb fat. Occurring in the fingerlike villi of the ileum, lacteals have a milky appearance and drain into the lymphatic system.

Detailed explanation-3: -The intestinal cells absorb the fats. Long-chain fatty acids form a large lipoprotein structure called a chylomicron that transports fats through the lymph system. Chylomicrons are formed in the intestinal cells and carry lipids from the digestive tract into circulation.

Detailed explanation-4: -1. Villi That Line the Walls of the Small Intestine Absorb Nutrients. Villi that line the walls of the small intestine absorb nutrients into capillaries of the circulatory system and lacteals of the lymphatic system. Villi contain capillary beds, as well as lymphatic vessels called lacteals.

Detailed explanation-5: -A lacteal is a lymphatic capillary that absorbs dietary fats in the villi of the small intestine.
