Text C. New Investigations on the Vascular Structure of the Heart

Great work on modern anatomy was begun in the 15th and 16th centuries. Such great men as Leonardo da Vinchi, Vesalius, Servet and Harvey did much to study the structure of the human body.

In the 20th century anatomy became an exact science. Scientists considered that no new discoveries could be made in this field.

But in 1968 Prof. Seraphima Samoilova, a surgeon — a student of Sergei Udin, who worked in Leningrad, began to study the heart vessels.

Anatomists always considered that the heart was mainly a muscular organ. The heart chambers, the valves, the muscular bands and the coats were well described. But not much was said about the heart vessels.

Seraphima Samoilova determined that the heart consisted of thin vascular tubes. Half of the heart weight was composed of the bands of vessels. She came to the conclusion that the heart was a dilated large vessel included in muscular tissues.

The structure of the heart as a band of vessels is very intricate [‘intrikit] (сложный) and varies with age and diseases.

Seraphima Samoilova included all the findings of her research work into the book called The Anatomy of Cardiac Blood Vessels.

This book was published in Leningrad in 1970. It helps surgeons to perform operations on the heart.

Text A. Work of the Human Heart

The human heart contracts from the first moment of life until the last one. The contractions of the heart pump the blood through the arteries to all the parts of the body. Scientists have determined that the total weight of the blood pumped by the heart daily is about ten tons.

The rate of Heart contractions is regulated by two groups of nerve fibers. It varies in different persons and at different age.

Physiologists have determined that in the adult the heart makes from 60 to 72 beats per minute. In children the rate of heartbeat is much higher. Research work of many scientists has helped to determine that the rate of heartbeat increases depending on different emotions.

Each beat of the heart is followed by a period of rest for the cardiac muscle. Each wave of contraction and a period of rest following it compose a cardiac cycle.

Research work has given physiologists the possibility to find out that the heart muscle works or contracts about one third of the time of the person’s life. The period of rest is shorter during greater physical exertion and longer when the body is at rest.

Each cardiac cycle consists of three phases: physiologists have called the first phase of short contraction of both atria—the atrial systole. They have called the second phase of a more prolonged contraction of both ventricles—the ventricular systole. The period of rest of the cardiac muscle is called the diastole.

The left ventricle discharges out the blood received by the left atrium from the pulmonary circulation through the aorta to the systemic circulation.

The blood received from the systemic circulation by the right atrium is discharged out of the right ventricle to the lungs through the pulmonary arteries.

Prolonged research work of many physiologists has given the possibility to estimate the role of the ventricles which serve as the main pump. The atria act as receiving chambers. The contraction of the atria which sends the final portion of the blood into the ventricle is considerably less.
