how does the digested food get absorbed by the blood
Answers
Answer:
digested food molecules get absorbed by the small intestine..so as they pass through the small intestine and then go to the bloodstream...
hi mate,
==>we know that during food absorption, food molecules enter the bloodstream through the intestinal walls.
==>Capillaries (microscopic blood vessels) within the villi absorb products of protein and carbohydrate digestion.
==>Lymph vessels (lacteals) within the villi absorb products of fat digestion and eventually lead to the bloodstream
,
==> we know that the Columnar epithelium is located in the digestive tract such as the stomach, large intestine, small intestine and functions as a barrier to bacteria and other microbes but permits the absorption of digested food.
==> we know that the small intestine has millions of tiny finger-like projections called villi.
==>These villi increase the surface area for more efficient food absorption. that's why
small intestine is designed to have maximum absorption of food.
==>Within these villi, many blood vessels are present that absorb the digested food and carry it to the blood stream.
i hope it helps you.
