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 atrioventricular 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. The 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 one. The valves are located at the entrance and exit (выход) of each ventricle.

The muscular structure of the heart consists of fibrous bands divided into two groups — the first ones are the fibrous bands of the atria and the second ones are the fibrous bands 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 system. They are called the systemic vessels.

The pulmonary system 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.

The heart is a vital organ in the human body, responsible for pumping blood throughout the circulatory system. It is located within the chest, enclosed in the pericardium. The base of the heart rests against the third rib, while the apex is positioned between the fifth and sixth costal cartilages. In terms of weight, the heart typically weighs around 300 grams in males and 220 grams in females.

Anatomically, the heart is divided into two chambers by a septum. Each chamber consists of two parts - the atrium and the ventricle. The atrioventricular valves separate these parts, ensuring the proper flow of blood.

The right atrium is larger than the left atrium, while the walls of the left atrium are thicker. The right ventricle is triangular in shape with thick walls, located in the anterior part of the heart. On the other hand, the left ventricle is longer and more conical, with walls three times thicker than those of the right ventricle. Valves are situated at the entrance and exit of each ventricle.

The heart's muscular structure is made up of fibrous bands, categorized into bands of the atria and bands of the ventricles. The vascular system includes arteries, veins, and capillaries, which transport blood throughout the body. The systemic vessels carry blood to and from tissues, the pulmonary system deals with blood flow to and from the lungs, and the portal system consists of veins leading to the liver.

Arteries typically have three coats and are capable of dilation and contraction in sync with the heart's pumping action. Overall, the heart and vascular system work together to ensure proper blood circulation and oxygen delivery to all parts of the body.

Сердце — это внутренний полый мышечный орган, расположенный в грудной клетке и заключенный в перикард. Основание сердца находится у третьего ребра. Его верхушка находится в межпространстве между пятым и шестым реберными хрящами. Масса сердца составляет около 300 граммов у мужчин и около 220 граммов у женщин.

Сердце состоит из двух отдельных камер, разделенных перегородкой. Каждая из камер имеет две соединенные части: предсердие и желудочек. Атриовентрикулярные клапаны разделяют предсердия и желудочки.

Правое предсердие больше левого, но стенки левого предсердия толще, чем у правого. Правый желудочек имеет треугольную форму и толстые стенки. Правый желудочек находится в передней части сердца. Левый желудочек длиннее и более конусообразный, чем правый. Стенки левого желудочка в три раза толще стенок правого. Клапаны расположены на входе и выходе каждого желудочка.

Мышечная структура сердца состоит из фиброзных полос, разделенных на две группы — первые из них это фиброзные полосы предсердий, а вторые — фиброзные полосы желудочков.

Сосудистая система состоит из трех групп сосудов — артерий, вен и капилляров.

Сосуды, несущие кровь к тканям тела и от них, составляют общую систему. Они называются системными сосудами.

Легочная система образована сосудами, несущими кровь к легким и от них.

Портальная система образована венами, идущими к печени.

Большинство артерий состоят из трех оболочек. Артерии расширяются и сужаются одновременно с действием сердца.
