Anatomy of the heart in 1 minute | Heart structure | Smart Medic [SM] vessels and valves • And so, we will analyze the structure of the heart in just 1 minute. The heart has 4 chambers: 2 atria and 2 ventricles. Denote: right atrium, left atrium, right ventricle and left ventricle. Between the atria is the interatrial septum, between the ventricles is the interventricular septum. From the left ventricle, the aorta leaves and carries arterial blood to the organs and tissues. From the right ventricle there is a pulmonary trunk and carries venous blood to the lungs. In the right atrium flow into the upper and lower hollow veins, which carry venous blood from the upper and lower extremities. In the left atrium, 4 pulmonary veins flow, which carry arterial blood from the lungs. Between the left atrium and the ventricle is a mitral valve. Between the right atrium and the ventricle is the tricuspid valve. Also, denote the aortic valve and the valve of the pulmonary trunk. The heart has 3 layers: the outer - epicardium, the middle-myocardium, and the inner - the endocardium. • Subscribe to the channel Smart Doctor - goo.gl/h55jMo • Vkontakte - https://vk.com/medic_smart • Instagram - / best_medics • My pages in social networks: • Vkontakte - https://vk.com/sinelnykoff • Facebook - / sinelnykoff • YouTube - https://goo.gl/zSzozD
