Abdomen, in human anatomy, the body cavity lying between the chest or thorax above and the pelvis below and from the spine in the back to the wall of abdominal muscles in the front. The abdomen is the frontal body cavity between the chest and pelvis that holds vital organs like the stomach, kidneys, bladder, liver, and intestines. The abdomen contains many of the body’s vital organs and plays a central role in digestion, circulation and immunity This section examines the layered anatomy of the abdominal wall and the organisation of the internal viscera. The major organs of the abdomen include the small intestine, large intestine, and stomach Together, these three turn nutrients into usable energy, as well as help dispose of solid waste.
The abdomen surface anatomy is divided into quadrants, regions, and planes, which help to localize the anatomical positions of various abdominal organs There are four quadrants, which are the right upper quadrant, the left upper quadrant, the right lower quadrant, and the left lower quadrant. So, it is crucial that you cover this section thoroughly This page will introduce you to the most important anatomical features of the abdomen and pelvis and serve as a hub from which you can hop into more detailed study materials.
