What is referred to as the lower part of the ventral cavity?

The lower part of the ventral cavity is known as the abdominopelvic cavity. This cavity is subdivided into two sections: the abdominal cavity, which houses organs like the stomach, liver, and intestines, and the pelvic cavity, which contains the bladder, reproductive organs, and part of the large intestine. The ventral cavity itself is divided into two main regions: the thoracic cavity, located superior to the diaphragm, and the abdominopelvic cavity, situated inferior to it. Understanding this anatomical distinction is crucial for comprehending how various body systems are organized and how they function relative to one another. The other options represent different anatomical areas that do not encompass the lower part of the ventral cavity, such as the thoracic cavity, which is primarily associated with the chest and respiratory organs, the cranial cavity, which houses the brain, and the spinal cavity, which contains the spinal cord.
