Question

multiple choice question
the parietal pleura meets the visceral pleura at the ______ of each lung.
o apex
o base
o hilum

Explanation:

The parietal pleura and visceral pleura meet at the hilum of the lung. The hilum is the area where structures like bronchi, blood vessels, and nerves enter and exit the lung. At this location, the two layers of the pleura (parietal - lining the thoracic cavity; visceral - covering the lung surface) are continuous. The apex is the top part of the lung, and the base is the lower part (resting on the diaphragm). But the meeting point of the two pleural layers is specifically at the hilum.

Answer:

hilum
