Answer 2

Blood circulation system consists of the heart, its two atriads, two ventricles, their function, blood purification in the pleura and the arteries carrying pure blood to each of the organs and veins that bring back impure blood to the heart.

Explanation:

There are plasma, red blood cells, white blood cells etc. in the blood. One cubic mm of human.

There are 50,00,000 red blood cells and 6,000 to 9,000 white blood cells in the blood. Blood does not freeze in the body, but as soon as it comes out of the body, the blood starts to freeze.

The vertical and semi-hemispheres bring the blood of the entire body into the atrium in the south of the heart, from where the blood enters the southern ventricle.

Due to the pulsation of the heart from the ventricles, the blood travels to the pleura by the pulmonary artery and after being purified it enters the left atrium by the pulmonary veins.

Due to the contraction of the left atrium, the blood enters the left ventricle from where the aorta and its branches enter the entire body.

There is impure blood in the veins and pure blood in the arteries, but the pulmonary artery and renal artery are exceptions.

Heart pulsing occurs 72 times in a minute. The heart is covered with cardiomyopathy.

There is a valve between the atrium and ventricle, which prevents the blood from going in the opposite direction.
