New intestinal cells are born at the base of the villi, and they migrate to the tips of the villi where—at the “old age” of three days—they come off.

The food passes to the stomach where it is churned and mixed with acidic gastric juice that begins the digestion of protein. The pancreas produces pancreatic juice that contains many of the enzymes secreted into the small intestine. In addition to producing bile the liver regulates blood sugar levels by converting glucose absorbed by the villi into glycogen and storing it.

These components are processed by cells throughout the body into energy or are used as building blocks. The digestive system is composed of the mouth, pharynx, esophagus, stomach, small intestine, large intestine (or colon), rectum, and anus. There are four steps in the digestion process: ingestion, the breakdown of food, nutrient absorption, and elimination of indigestible food.

The hypothalamus triggers feelings of either hunger or satiety (fullness) by integrating signals from nerve cells, hormones, and the amount and type of food we eat.

Glands in the wall secrete gastric juice that contains enzymes to digest protein and fats as well as hydrochloric acid to make the contents very acidic. The walls of the stomach are very muscular and churn and mix the food with the gastric juice to form a watery mixture called chyme (pronounced kime). Rings of muscle called sphincters at the entrance and exit to the stomach control the movement of food into and out of it (see diagram 11.9).
