How does the food that we eat gives us energy? Most of us just eat food either to overcome the hunger or to satisfy cravings, but do we really understand where the food goes after it enters the -

MOUTH - Starches are partially digested by saliva in the mouth. The swallowed food goes down the esophagus into the stomach.

STOMACH - The chewed food is liquified with gastric juices and ground down into smaller particles. Protein is broken into amino acids. The food gradually empties into the small intestine where the nutrients become available to the body. Water can empty from the stomach at the rate of about 1 Quart/hr (quart=The quart is a unit of volume equal to a quarter of a gallon (hence the name quart) four cups. ; solid food take longer. Empty time depends on the caloric density.

SMALL INTESTINE - Starches break into simple sugar. Protein is further digested into amino acids and fat into fatty acids. These digestive products are then absorbed into the bloodstream and either used or transported to the liver. The indigestible waste products move into the large intestines.

LIVER - Receives digested food components and stores extra glucose to be released into the blood stream for further use.

LARGE INTESTINES - Receives indigestible waste products, reabsorbs water and minerals and excretes waste as feces.
