Pleura of the Lungs. Each lung is enclosed within a cavity that is surrounded by the pleura. The pleura (plural = pleurae) is a serous membrane that surrounds the lung. The right and left pleurae, which enclose the right and left lungs, respectively, are separated by the mediastinum.he major function of the lungs is to perform gas exchange, which requires blood from the pulmonary circulation. This blood supply contains deoxygenated blood and travels to the lungs where erythrocytes, also known as red blood cells, pick up oxygen to be transported to tissues throughout the body.
The pleura (the covering of the lungs). There are 2 fibrous sheets of tissue that cover the lungs and help to protect them. These are callled the pleura or pleural membranes. Doctors usually call these the lining of the lungs, although this can be a bit confusing as they are on the outside.The gap between the pleura is called the pleural space.lose to the lungs and airways are lymph nodes (also called lymph glands). They are small bean shaped glands found throughout the body. They are connected by a network of tubes called lymphatics or lymphatic vessels. This network carries a fluid that leaks out of the blood vessels and bathes the body tissues and cells.
