The pleural sac is a critical anatomical structure comprising the parietal and visceral pleura, containing the pleural cavity. This cavity is vital for respiratory function, allowing smooth movement during lung expansion and contraction. The interlobar recess and mediastinal pleura encompass the complex anatomy of the pleural sac, supported by mesothelial tissue. Understanding these components is essential for comprehending respiratory physiology and pathology.
