Answer:
Visceral pleura
Explanation:
The pleura forms the main component of the respiratory system whose main objective is to carry out the process of respiration without any difficulty and also to reduce friction during the time of breathing.
It is basically comprised of two types namely-
(1) The Parietal pleura
(2) The Visceral pleura
The visceral pleura can be usually referred to as one of the important and fine membranes that surround the surface of the lungs. It is separated by the parietal pleura due to the presence of a pleural fluid between them.
On the other hand, the parietal pleura is responsible for surrounding the internal portion of the chest cavity and is comparatively thicker than the visceral pleura.
