The second function of the lymphatic system is the absorption of fats and fat-soluble vitamins from the digestive system and the subsequent transport of these substances to the venous circulation. The mucosa that lines the small intestine is covered with fingerlike projections called villi.

Which circulatory system carries most of the fats and fat soluble nutrients?

Immediately after absorption, lymphatic system carries most of the fat-soluble nutrients.

What circulatory system carries fat?

Though digested fats are absorbed by lymphatic capillaries, it is ultimately drained into left subclavian vein by left thoracic duct (= major lymphatic duct).

Where does most absorption occur in the digestive system?

The small intestine is the part of the gastrointestinal tract between the stomach and the large intestine where much of the digestion of food takes place. The primary function of the small intestine is the absorption of nutrients and minerals found in food.

How are lipids absorbed by the digestive system?

In the stomach fat is separated from other food substances. In the small intestines bile emulsifies fats while enzymes digest them. 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.

Which of the following regulates the pH of the stomach?

Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin.
