Text A. The Heart and the Vascular System




The heart is an inner hollow muscular organ placed within the chest and in­cluded in the pericardium. The base of the heart is against the third rib. Its apex is against the interspace between the fifth and sixth costal cartilages. The weight of the heart is about 300 grams (gr) in the male and about 220 gr in the female.

The heart consists of two separate chambers divided by the septum. Each of the chambers has two connected parts: the atrium and the ventricle. The atrio-ventricular valves separate the atria from the ventricles.

The right atrium is larger than the left one, but the walls of the left atrium are thicker than those of the right one/The right ventricle is triangular (треугольный) in form and has' thick walls. The right ventricle is in the anterior part of the heart.jffbe left ventricle is longer and more conical than the right one,? / The walls of the left ventricle are three times as thick as the walls of the right oneyThe valves are located at the entrance and exit (выход) of each ventricle.

The muscular structure of the heart consists of two parts - the muscular layers of the atria and the muscular layers of the ventricles.

The vascular system consists of three groups of vessels - arteries, veins and capillaries.

The vessels carrying blood to and from the tissues of the body compose the general circulation. They are called the systemic vessels.

wThe pulmonary circulation is formed by the vessels carrying blood to and from the lungs.

The portal system is formed by the veins passing to the liver.

Most of the arteries are composed of three coats. The arteries dilate and contract simultaneously with the action of the heart.

Text В

 

In the left chamber the atrium and ventricle are separated by the mitral ['maitral] valve.

In the right chamber the atrium and ventricle are separated by the tricuspid [trai'kAspid] valve.

At the point of origin of the aorta in the left ventricle another valve is lo­cated. This valve is called the semilunar [,semi'lu:n3] valve of the aorta.

At the point of origin of the pulmonary artery in the right ventricle the fourth valve is located. It is called the semilunar valve of the pulmonary artery.

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 are 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 gr. The right lung is about 15% heavier than the left one. The vital capacity of the lungs is 3.5-4 litres in the male and it is 3-3.5 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 coveredwith 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.

XV. Read Text D. Entitle it:

TextD

 

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.

It then goes to the border of the fourth lumbar vertebra and here it finishes dividing into the left and right iliac arteries.
