Our Amazing Human Body: The Heart

They say that a person without a heart is one who has no feelings and say nothing more. For me the Heart is surprising by its function and its form.

The heart is the muscle that pumps blood rich in oxygen and nutrients to the tissues of the body through blood vessels.

The heart keeps the blood moving in the body unidirectionally, it is a closed circuit, nothing is lost. The atria receive blood returning to the heart, the ventricles pump blood from the heart out.

The arteries carry the oxygenated blood from the heart to the tissues of the body. In the tissues the nutrients are extracted and returned through the veins. The veins carry the blood back to the heart.

Taking care of our heart is very important, for this reason it is essential to avoid foods that are too salty and too sweet, just like tobacco and alcohol. Another recommendation that is important to repeat until the fatigue is to try to exercise regularly, because with these simple practices avoid many health problems, especially all that have to do with complications of the heart.
