Lungs are the main organs of respiration. Ty lie in thoracic cavity. Right-lung is 3-lobed and left-lung two-lobed. The cone shaped space among two lungs is termed as mediastinum. Each lung is enclosed by a two-layered membrane. Its outer membrane is termed as parietal pleura and inner visceral pleura. The space among such two membranes is termed as pleural cavity that is filed with a serous fluid. Such fluid lubricates the lungs and defends them from friction.
