Why does absorption of digested food mainly occur in the small intestine?

as the the molecules of food becomes so small that they can pass through the walls of small intestinewhich contain blood capillaries and go into our blood.

In which structure does most of the absorption of nutrients occur?
Small intestine
Where does the most digestion occur in the human body?
Vitamins are absorbed (not actually digested) in both the small intestine and the large intestine. Some water-soluble vitamins are released by the action of helpful bacteria in the large intestine.
Where do filtration of the blood and re-absorption of nutrients occur?
filteration of blood:- is in the kidney absorption of nutrients :- is in the small intestine
Where does water reabsorption occur?
Between tubular elements and vascular elements of the nephron beginnings with the proximal convoluted tubule and continuing at least part way into the distal tubule.
Why does the absorption of nutrients occur in the small intestine and not the stomach?
the walls of the stomach is alkaline and the food contain in the stomach is acidic.. it will not accept the nutrients to enter inside the stomach walls. the small intestine having villa in the walls and it ll absorb the nutrients in the food.
Where absorption of water occur?

Digestion begins in the?
Digestion of some fats can begin in the mouth where lingual lipase breaks down some short chain lipids into diglycerides. However fats are mainly digested in the small intestine. The presence of fat in the small intestine produces hormones that stimulate the release of pancreatic lipase from the pancreas and bile from the liver which helps in the emulsification of fats for absorption fatty acids.
How long does it take the large intestine to digest food?
Very little digestion occurs in the large intestine. Food is in the stomach for 2 1/2 to 5 hours. It is broken down and spends another 5 - 6 hours in the small intestine where absorption of macro and micro nutrients occur from whatever is eaten. The residue, waste, and undigested fiber enters the large intestine after that. Two things occur in the large intestine. Water is absorbed and circulated back into the bloodstream and healthy bacteria that live there continue the breakdown of undigested food and waste. Sadly most people have a transit time of 50 - 60 hours. This means something eaten 2 days ago is still in the large intestine in some form. Eating a high fiber diet can reduce transit time to 18 - 24 hours. This reduces the absorption of toxins in the large intestine.
