Text С. The Lungs

The lungs are the main organs of the respiratory system. There are two lungs in the human body located in the lateral cavities of the chest. The lungs are separated from each other by the mediastinum. The lungs are covered with the pleura. They are conical in shape. Each lung has the base, apex, two borders and three surfaces.

The lung has the apex extending upward 3-4 centimetres (cm) above the level of the first rib.

The base of the lung is located in the convex (выпуклый) surface of the diaphragm.

The posterior borders of the lungs are on each side of the spinal column. The anterior borders thin and overlap (перекрывать) the pericardium.

The weight of the lungs varies according to many conditions. In the adult male the weight of the lungs is about 1,350 grams (g). The right lung is about 15% heavier than the left one. The vital capacity of the lungs is 3.5-4.0 litres

(l) in the male and it is 3.0-3.5 litres in the female.

The right lung consisting of three lobes is heavier than the left one because the latter consists only of two lobes. The lower lobe of the left lung is larger than the upper one.

In infants the lungs are of a pale rose colour, but later they become darker.

The lung is covered with an external serous coat, i.e. with visceral layer of the pleura. The parenchyma or proper substance of the lungs consists of the bronchial tree with elastic tissue and vessels.

The aorta is the main vessel of the systemic arteries or the arteries of the general system. It begins at the upper part of the left ventricle, goes up, arches over the root (корень) of the left lung to the left side of the trunk at the level of the fourth thoracic vertebra. On its way from the fifth thoracic vertebra to about the level of the last thoracic vertebra it is called the thoracic aorta. Then it goes down through the diaphragm. From the point of the last thoracic vertebra to the level of the fourth lumbar vertebra it is called the abdominal aorta.
