As this serous membrane is in the lungs is called the visceral pleura. When the same membrane of the esophagus, great vessels and heart, called the mediastinal pleura. Because atmospheric pressure is the pressure between the parietal and visceral pleura low. This leads to friction between the membranes in which the lungs expand and collapse during breathing. This friction is reduced due to the presence of serum secret. The two major vital organs, including the chest cavity and lungs.
The cardiovascular system is in the chest cavity. It also contains large blood vessels such as aorta, pulmonary artery, upper and lower vena cava and pulmonary vein and azygos vein.
