Food enters the human digestive tract through the mouth.

Moving food from one digestive organ to the next (swallowing)

Purpose is to mechanically and chemically breakdown food to allow nutrients to be absorbed into the bloodstream.

This allows the digestive food materials into the body cells. In most instances, this occurs when building blocks enter the small intestine’s mucosal cells .( highly specialized cells for maximizing digestion and absorption of nutrients.

The process of transport and use of absorbed nutrients.

This is the elimination of indigestible residues or solids wastes ( in the form of feces) from the digestive tract through the rectum.

This is the cutting and chewing of food into smaller pieces using the teeth.

This is the process of adding water (saliva) to food.

It is the act of moving food from the mouth to the pharynx (swallowing)

This is the mixing and grinding action of the stomach contents that results from the contractions of the stomach muscles.

This is facilitated by the wavelike contraction of the digestive system's muscular food tube.
