The abdominal cavity is a large space within the body that houses several vital organs. It is located between the diaphragm and the pelvis and is part of the larger ventral body cavity. This cavity contains organs such as the stomach, liver, intestines, and kidneys, which are essential for digestion, metabolism, and waste elimination. The abdominal cavity is lined by a protective membrane called the peritoneum, which helps reduce friction between the organs. It also plays a role in supporting the organs and providing a pathway for blood vessels and nerves. Understanding the structure and function of the abdominal cavity is important in fields like medicine and anatomy.
