Pleura: Understanding the Lining of Your Chest Cavity | Medical Definitions

The medical term meaning lining of the chest cavity is pleura. The pleura is a thin, double-layered membrane that lines the thoracic cavity and covers the lungs. It consists of two layers: the visceral pleura, which is in direct contact with the lung tissue, and the parietal pleura, which lines the thoracic cavity. The pleural space is the potential space between the visceral and parietal pleura.
