What does the abdominal cavity contain?

The abdominal cavity primarily contains most digestive organs, the spleen, kidneys, and ureters. This cavity is a major compartment of the human body, situated below the thoracic cavity and above the pelvic cavity. It is lined by a membrane called the peritoneum, which helps support the abdominal organs and allowable movement.

The organs situated within the abdominal cavity include the stomach, liver, pancreas, intestines, and gallbladder, all of which are vital for digestion and nutrient absorption. Additionally, the kidneys, which are responsible for filtering blood and producing urine, as well as the ureters, which transport urine from the kidneys to the bladder, are also housed here. The inclusion of the spleen, which plays a crucial role in immune function and the recycling of blood cells, further emphasizes the significance of this cavity.

In contrast, other options identify different cavities and organs that are not situated within the abdominal anatomical region. The heart and lungs are contained in the thoracic cavity, the brain and spinal cord are part of the cranial and vertebral cavities respectively, and the urinary bladder and reproductive organs primarily reside within the pelvic cavity. This distinction highlights the specific nature of the abdominal cavity's contents.
