Funny and interesting information about the heart that you did not know
The heart is like a pump made of muscle, which pushes blood into the body through vessels and consists of two parts, one left and one right, as well as four chambers: an atrium and a ventricle on each side. The atrium receives large vessels, which bring blood to the heart, and has special valves that open into the ventricle.
The ventricles, in turn, have valves that open into the blood vessels. The right side of the heart receives non-oxygenated blood from the body, and after it passes through the right atrium and right ventricle, the blood is pumped into the lungs. Here the blood is oxygenated and removes carbon dioxide. After passing through the lungs, the blood reaches the left atrium, then the left ventricle, from where it is pumped into the aorta, through which it is distributed throughout the body through the arteries.
Because the heart is a vital organ, it is important to keep it healthy with a well-balanced diet and exercise and to avoid things that can damage it, such as unhealthy eating, alcohol, smoking or drugs.
