Question

Английский, помогите с переводом) 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.

Answer 1

Сердце -- внутренний полый мышечный орган,расположенный в грудной клетке и заключённый в перикард. Основная часть сердца расположена на уровне третьего ребра. Вершина -- на уровне интервала между пятым и шестым рёберным хрящом. Вес сердца составляет примерно 300 грамм у мужчин и 220 у женщин.

Сердце состоит из двух отдельных камер,разделённых перегородкой. Каждая из камер имеет две части: предсердие и желудочек. Друг от друга их отделяют предсердно-желудочковые клапаны.

Правое предсердие больше левого,но стенки левого толще,чем у правого. Правый желудочек треугольный,с толстыми стенками. Правый желудочек -- передняя часть сердца. Левый желудочек длиннее и имеет более конусообразную форму. Стенки левого желудочка в три раза толще стенок правого. Клапаны расположены на входе и выходе из каждого желудочка. Мышечная структура сердца состоит из фиброзных связок,подразделяющихся на две группы: фиброзные связки предсердия и такие же желудочка. Сосудистая система включается три группы сосудов: артерии,вены и капилляры.

Сосуды несут кровь к тканям и из них,составляя общую систему. Зовутся они системными сосудами. Малый круг кровообращения формируется сосудами,несущими кровь к лёгким и от них. Портальная система -- несущими кровь к печени. Большинство артерий состоят из трёх слоёв. Артерии расширяются и сокращаются согласно с движениями сердца.

Answer 2

The heart is an inner hollow muscular organ located within the chest and enclosed in the pericardium. It is positioned with its base against the third rib and its apex against the interspace between the fifth and sixth costal cartilages. The weight of the heart is approximately 300 grams in males and about 220 grams in females. The heart is divided into two separate chambers by the septum, each consisting of 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 atrium, but the walls of the left atrium are thicker than those of the right atrium. The right ventricle is triangular in shape and has thick walls. It is located in the anterior part of the heart. On the other hand, the left ventricle is longer and more conical than the right ventricle, and its walls are three times as thick as those of the right ventricle. The valves are located at the entrance and exit of each ventricle. The muscular structure of the heart consists of fibrous bands divided into two groups: the fibrous bands of the atria and the fibrous bands of the ventricles.

The vascular system consists of three groups of vessels: arteries, veins, and capillaries. The arteries carry blood away from the heart to the tissues of the body, while the veins carry blood back to the heart. Capillaries are tiny blood vessels that connect the arteries and veins and allow for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. The vessels that carry blood to and from the tissues of the body make up the general system and are called the systemic vessels. The vessels that carry blood to and from the lungs form the pulmonary system. Additionally, there is a portal system formed by the veins that pass to the liver.

Most arteries are composed of three coats, or layers, which include the tunica intima (innermost layer), the tunica media (middle layer), and the tunica adventitia (outermost layer). The arteries dilate and contract simultaneously with the action of the heart, helping to regulate blood flow throughout the body.
