If you put your little hand on the left part of your chest you will feel that there is something inside you that moves and goes pum – pum. Do you know what it is? Yes, of course you know: the heart.

The heart is a fairly small muscle, about the size of your fist. It is located inside the chest and between two organs that allow us to breathe called lungs.

The heart fulfills a very important mission: it pumps the blood so that it circulates throughout the body. Every time it beats it propels it through the arteries and veins.

The heart is something like an engine that works day and night without rest so that the blood is always in motion.
