The four quadrants of the abdominal cavity
The abdominal cavity in the human body has four parts or quadrants, located inside our abdomen. First, the upper-right quadrant consists of the liver, stomach, duodenum, pancreas, colon, transverse colon and right kidney. The upper quadrants are located above the others because they contain the organs which are first to assimilate food and begin the chemical processes of digestion. Liquids produced by different organs, like bile produced by the liver and acid produced by the stomach, mix with food as it passes through the stomach.
The partially digested food then travels to the duodenum, where nutrients are absorbed through the intestinal walls. It then flows into the colon, where more nutrients are absorbed, squeezing out as much useful nutrition and vitamins as possible. After that, it passes to the transverse colon to be decomposed into feces with the help of E. coli bacteria.
There are three more quadrants of the abdominal cavity. The upper-left quadrant contains the left lobe of the liver near the stomach, the stomach, jejunum, proximal ileum, and spleen. It also is home to the pancreas body and tail, left kidney, and other vital organs around the stomach and left portion of the colon.
Organs found in the lower-right quadrant of the abdominal cavity include the cecum, vermiform appendix, as well as the right ovary and Fallopian tube in women. The lower-left quadrant consists of other organs found on the lower left side of the abdomen, including the left ovary and Fallopian tube in women.
Just like the abdominal cavity itself, our post “Quadrants of the Abdominal Cavity” is divided into four parts for a simple and clear explanation of the organs inside your body. This explanation, combined with our other articles, can help give you information about every part of your body and its organs.
