Finger-like structures that cover the inner wall of the small intestine?

These are called villi and there are millions of them that line the small intestine and large intestine (Colon) they absorb the nutrients particularly in the Colon where they absorb liquid into the blood stream. This is what makes your stools hard (constipation) and painful to pass if you wait too long to go for a number 2. The peristaltic action moves the liquid along the small and large intestines.
