The pleura is a double-layered serous membrane that lines the walls of the thoracic cavity and the surface of the lungs Lungs Lungs are the main organs of the respiratory system. Lungs are paired viscera located in the thoracic cavity and are composed of spongy tissue. The primary function of the lungs is to oxygenate blood and eliminate CO2. Lungs: Anatomy. Thus, it extends virtually as far and wide as the thoracic cavity.

arteries
Arteries
Arteries are tubular collections of cells that transport oxygenated blood and nutrients from the heart to the tissues of the body. The blood passes through the arteries in order of decreasing luminal diameter, starting in the largest artery (the aorta) and ending in the small arterioles. Arteries are classified into 3 types: large elastic arteries, medium muscular arteries, and small arteries and arterioles.
Arteries: Histology. The visceral pleura receives blood supply from the bronchial and pulmonary vessels.
