Nutrients are absorbed by the blood vessel in the small intestines. Special cells in the small intestines are facilitate this movement.

the small intestines can't absorb nutrients as well
absorbs water and nutrients and feed them to cells
Columnar epithelium forms the lining of the stomach and intestines
Alcohol can damage the cells lining the stomach and intestines, which can block the absorption and breakdown of nutrients in those organs.
Food passes from:the mouthto esophagusto the stomachto the small intestines (where the cells pull fluid into the intestines)to the large intestines (where cells shuttle fluids back to the kidneys)and waste then enters the rectumto the anus, and into the toilet.

Because they are smaller then the big intestines. So they are referred to as the small intestine.
The structures that produce new cells for the mucosa of the small intestines are the intestinal crypts. These crypts contain stem cells that continually divide and give rise to new cells that migrate up and replace the old cells on the surface of the intestinal lining. This process helps maintain the integrity and functionality of the mucosa.
When your food is being digested and it is in your small intestines and the villi sucks up the nutrients it gives the nutrients to blood vessels which take it to your cells. Small intestines and villi are parts of digestive system. Blood vessels and cells are part of circulatory system.
