Final answer:
The pleural cavity is part of the thoracic cavity, which is located in the anterior section of the body and contains the lungs.
Step-by-step explanation:
The pleural cavity is part of the thoracic cavity. In the human body, there are two major cavity divisions, the dorsal cavity and the ventral cavity. The ventral cavity is the anterior (front) section of the body and it's further divided into two parts: the thoracic cavity, which is the upper part, and the abdominopelvic cavity, which is the lower part. Located within the thoracic cavity, the pleural cavity specifically houses the lungs, with each lung occupying its own pleural cavity. The thoracic cavity is separated from the abdominopelvic cavity by the diaphragm, a muscle important for respiration.
