The nutrients that are absorbed through the wall of the small intestine get absorbed by the capillary network within the villi and they will come together to form the hepatic portal vein that goes directly to the liver for processing.
Capillaries are basically tiny blood vessels. There are many in your lung's alveoli so the blood can go through gas exchange. Gas exchange being the process of which deoxygenated blood switches the waste (Co2) is has extracted from its last circulation for oxygen from the alveolus, the then oxygenated blood heads to the heart from the lungs to be pumped out from the Aorta and arteries. Capillaries are also found in your muscles so when oxygenated blood reaches those muscles the blood has a route of which it can transfer the oxygen into the muscle tissue and extract the waste. Then it goes back into the heart as deoxygenated blood and is pumped into the lungs once again and thus continues circulation. :)
they help the blood absorb amino acids, fatty acids, and glucose
In a nutshell, the digestion and absorption of nutrients from food ingested.
They help the blood absorb amino acids, fatty acids, and glucose.
Villi are located in the large intestine. They absorb excess water.
Is it true that intestinal villi contains capillaries and lacteals important for chemical digestion?
Villi (Sing. Villus)
To increase the surface area of which the products of digestion can diffuse across (into the blood)
Wherever capillaries are found, these are places where nutrients and wastes are exchanged.
Lacteals.
capillaries in the villi
the villi are tiny finger-like protrusions lining the small intestines. Digested food passes the villi and broken-down food molecules are absorbed through a wall of cells, and into tiny blood vessels inside the villi called capillaries. Nutrient filled blood from the capillaries joins the main bloodstream in veins around the intestines, ready to be used in other parts of the body. Having villi lining the intestines ensures maximum absorption of nutrients through a huge surface area.
