Stomach Basics
The stomach is a pear-shaped organ (some describe it as
"funnel-shaped"), between the liver and the spleen, located under the
diaphragm. Five layers of tissue make up the stomach. The
stomach provides a reservoir for holding food and allowing
the digestion process to begin.
The stomach is somewhat elastic because it changes size and
shape depending on the amount of food inside. The average adult
human stomach is generally about a foot in length (about 30 cm)
and about six inches (15 cm) from front to back at its widest
point. The stomach holds about one quart, or a little more than
.9 liters, of food and liquid.
Stomach function
Digestion or "food processing" is the main stomach
function. Food enters the stomach through the mouth, and then
the esophagus. Once food is in the stomach it starts being
broken down by gastric juices, or "stomach acid.". After the
stomach begins the digestive process, the food is passed out of
the stomach and into the small intestine.
Stomach problems
The stomach can be afflicted by a number of disorders,
diseases and problems, including stomach cancer and stomach
ulcers, which are serious. In addition, there are lesser
conditions related to the stomach which can cause temporary
discomfort, including stomach flu, stomach
bloating, stomach gas, and excess stomach acid. All of
these are covered in this website, so if you're having stomach
