How does the circulatory system Work?

Stress and Blood Circulation:

First we deal with the bloodstream. This is the path that our blood travels in the body. "Cycle" can only be understood in a broader sense, for he begins again where it ends. So seen, it runs in the "circle", we have a cycle. We it is in a circle just, we have neither a beginning nor an actual real end.

The heart plays a very important role in our bloodstream and ensures that it works at all. Since almost everything is in motion, we start here with the heart. It is a muscle that by the contraction and expansion - creates pressure - the contractions. In this case one speaks of the blood pressure. Thereby, the blood is pumped through the vessels in our blood. The heart itself consists of four cavities. As there would be the left and the right ventricle, each of which has still the atrium - the atrium.

From the left atrium the blood enters the left ventricle. Now it is from there pumped through the aorta into the arteries. The arteries are the blood vessels that are responsible for the distribution of oxygen-enriched oxygen in our body. The capillary, thin branches of the veins, ensure that the individual organs are well supplied with blood. They give off oxygen from the blood to the surrounding tissue and then takes it in addition to other metabolic products and carbon dioxide.

 

The now oxygen-poor blood is brought to the heart via the veins back. This time, however, it will placed in the right atrium, where it then goes back into the right ventricle. Now the blood is pumped from there into the lungs. The carbon dioxide is added to the respiratory air, we breathe the metabolite from the body. Meanwhile, the blood takes the oxygen which we breathe. Now again enriched with oxygen, the blood can be pumped back into the atrium of the left ventricle. Our bloodstream closes.
