World Heart Day: 14 curiosities about the heart to explain to children
We humans are, by spacing distances, like a car: we can function thanks to an engine that, in turn, works because substances are administered that give it energy. In the human body, the heart is the engine, and the substances are the nutrients that we take. At world day of the heart, we tell you 14 curiosities that you probably did not know about this muscle so you can tell them to your children.
The heart is a bomb that, with its driving action, provides the necessary force for the blood and the substance that it carries to circulate properly through the veins and arteries, as explained in the Heart Foundation.
In this way, in each heartbeat, our heart expels a certain amount of blood towards the thickest artery (the aorta) and, by successive ramifications that leave that artery, the blood reaches the whole organism.
All this procedure begins to learn in the years of Primary, the learning being much deeper as the years go by and the children get older. With everything, teaching the little curiosities about the human body is very positive because it will generate curiosity to continue learning about it, thus encouraging their desire to learn. With this objective, we tell you 14 curiosities about the heart that you may not know.
