Stomach

Description

stomach

The stomach is a muscular organ that is a sac like pouch where food is deposited via the esophagus. In humans, the stomach has a relaxed, near empty volume of about 45 ml. It normally expands to hold about 1 litre of food, but will hold as much as 1.5 liters. Adults eat about 500 kg of food per year. The average male will eat about 50 tons of food during his lifetime to keep a weight of 150 pounds. For the average person, it takes eight seconds for food to travel down the esophagus, three to five hours in the small intestine, and three to four days in the large intestine before excreted out.
