Question

Why are the ventricles of the heart so much larger than the atria of the heart? The ventricles receive blood from the rest of the body. The atria only receive blood and the ventricles have to pump blood to the lungs or the rest of the body The ventricles only carry oxygenated blood The atria only have to pump blood to the lungs

Answer 1

Answer:

The atria only receives blood and the ventricles have to pump the blood to the lungs or the rest of the body.

Explanation:

Our heart is divided into 4 chambers, two relatively small upper chambers called atria and two larger lower chambers called ventricles. The walls of the ventricles are much thicker than that of the atria and is necessary because ventricles have to pump the blood to lungs and all the body parts. The right and the left atria are separated by a thin, muscular wall called the interatrial septum whereas the right and left ventricles are separated by thick walled interventricular septum.

Answer 2

The atria only receive blood and the ventricles have to pump blood to the lungs or the rest of the body.
