Belly

Belly (/ˈbɛli/), also known as the abdomen, is the part of the body between the thorax (chest) and pelvis. The term "belly" is often used colloquially, while "abdomen" is more formal and is used in anatomical and medical contexts.

Etymology

The term "belly" comes from the Old English belg, which means "bag, purse". It is related to the Middle Dutch belg, the Old High German balg, and the Gothic balgs, all of which also mean "bag".

Anatomy

The belly or abdomen is divided into four quadrants: the right upper quadrant (RUQ), left upper quadrant (LUQ), right lower quadrant (RLQ), and left lower quadrant (LLQ). These quadrants are used to localize pain, masses, and other abnormalities.

The belly contains several important organs, including the stomach, liver, gallbladder, spleen, pancreas, small intestine, large intestine, and kidneys. It also contains several major blood vessels, including the aorta and the inferior vena cava.

  • Peritoneum: The membrane that lines the abdominal cavity and covers the abdominal organs.
