The heart is a pump that pumps blood necessary for life. The structure of the heart is constructed in such a way that it is possible to pump about 6 liters per minute, which gives 7 liters of blood per day. During the day, the heart contracts about 100 times. The structure of the heart enables the supply of blood to approximately 75 trillion cells in the body. How is it possible? Let’s take a closer look at the structure of the heart.
Structure of the heart is adapted to be able to provide nutrients and life-giving oxygen to all organs of our body in the most efficient way possible. From the organs, the blood vessel system drains metabolites, i.e. waste products, back to hearts.
Structure of the heart – let’s start from the beginning
Heart of an adult human being the size of a clenched fist. It is located in the so-called middle mediastinum, below the sternum, between the spine and the right and left lungs. Structure of the heart it is four-chamber: so we have two atria and two chambers.
Structure of the heart – right atrium and right ventricle
Structure of the heart it is constructed in such a way that the right atrium can collect blood from virtually all organs of the body (except the lungs). This process is possible thanks to the inferior and superior vena cava and the coronary sinus. Crimson-colored unoxidized blood flows into the right ventricle hearts through the tricuspid valve and then through the crescent-shaped valve, pulmonary trunk, pulmonary arteries to the lungs. There, gas exchange takes place and the outflowing blood is rich in life-giving oxygen. This is called bloodstream low, otherwise known as pulmonary. It is worth adding that pumping blood from the right ventricle takes place at a lower pressure than pumping blood from the left ventricle. This is due to the much shorter distance the blood has to travel. As a result, the wall of the right ventricle is thinner than that of the left ventricle.
Structure of the heart – left atrium and left ventricle
Left atrium hearts collects oxygenated bright red blood from the lungs. This is because v the structure of the heart We can distinguish as many as four pulmonary veins that fall into the left atrium: the upper left and lower left pulmonary vein, and the right upper right and right lower pulmonary vein. Blood flows into the left ventricle through the left atrioventricular opening equipped with a mitral valve. In turn, blood from the left ventricle is pumped into the aorta to the periphery. This is how the so-called bloodstream large (peripheral).
The inner structure of the heart – what is the heart made of?
Now let’s take a deeper look the structure of the heart – what is it really made of? Well, a thick wall hearts it consists of three layers. Going from the outermost layer construction of the heart, we can list: epicardium (pericardium), endocardium and endocardium. Pericardium it is made of two layers of connective tissue. Between the layers there is pericardial fluid that reduces friction during work hearts. Midday in turn, it is divided into three components: the heart skeleton, the heart muscle and the heart’s conductive system. Wessiercie in turn, it is composed of the endothelium and contains numerous blood vessels.
Composed of construction of the heart the aforementioned skeleton enters hearts built, among others from rings and fibrous triangles. The heart muscle, on the other hand, has a cross-striated structure with a varied structure in the atria and ventricles. While the exact muscle layers are not visible in the atria, these layers are visible in the ventricles. This is due to the high pressure in these cavities hearts. Discussing structure of the heart, or more specifically the muscle layers of the ventricles, we distinguish: the inner longitudinal layer, the middle circular layer and the outer oblique layer. It is important that the middle circular layer is responsible for generating the main contraction force of the heart muscle, while the outer oblique layer forms the so-called whirl of the heart.
Structure of the heart it is not only muscles and connective tissue, but also its own conductive stimulus system. It is an important component construction of the heartas it regulates the rhythm of work hearts. It consists of myocytes that have the ability to generate a nerve impulse.
Structure of the heart and its vascularization
Except that heart it has its own conductive system, it also has its own vascularization. They consist of the right and left coronary arteries and their numerous branches.
