The cardiovascular system is the system of blood circulation.The centre of the circulatory system is the heart. The human heart is a cone-shaped organ, about 5 inches1 long and 3 1/2 inches broad. It weighs about 10 ounces2 in the adult male, 6 ounces in the female. The heart is a hollow muscle which has four chambers. The right heart consists of an upper chamber, the atrium or the auricle and a lower chamber, the ventricle. The right heart receives blood from the veins and pumps it into the lungs by way of the lesser circulatory system. In the lungs the blood receives oxygen. Then it moves into the left heart. From the left heart the well-oxygenated blood moves into a large artery, the aorta.The blood returns to the heart by means of the veins. The smallest of these are the venules. The blood is a red fluid, which coagulates when escapes from a blood vessel. It consists of a colourless fluid, plasma or serum, and many millions of minute bodies, the corpuscles. - это уже возможно выучить!.
