Question

how the faeces is formed and stored in human intestine?​

Answer 1

Answer:

Partially digested food passes from the small intestine to the large intestine or colon.

Within the colon, digestion is retained long enough to allow fermentation via gut bacteria that break down some of the substances that remain after processing in the small intestine.

The large intestine houses over 700 species of bacteria that metabolize polysaccharides into short-chain fatty acids that produce large amounts of vitamins —especially vitamin K and biotin—and gas.

The normal flora of bacteria in the large intestine is essential in the development of certain tissues, including the cecum and lymphatics.

Explanation:

The feces is stored in the rectum for a certain period and then the stored feces is eliminated from the body due to the contraction and relaxation of the anus. The exit of this waste material is regulated by the anal sphincter.

Answer 2

Answer:

Water and Cellulose

The large intestine absorbs water from the chyme and stores feces until it can be defecated. Food products that cannot go through the villi, such as cellulose (dietary fiber), are mixed with other waste products from the body and become hard and concentrated feces.
