Is the atrium or the ventricle bigger?

Answer 1

The human hear has four chambers, two Atria and tow Venticles, one left and one right of each. The Right Atrium pushes blood into the Right Ventircle which then pushed the blood around the pulmonary (lungs) circulation. Once the Blood return, oxygenated, from the lungs it enters the Left Atrium which pushes it ito the Left Ventricle which in turn pushes the blood all around the body, including right up to the top of the head. Just by looking at the distance each chamber has to push the blood is a good indicator of the size of the musclular wall of each. The vetricles are therefore much larger than the atria and the left is much larger than the right.

Answer 2

The ventricles are thicker than the atria in the heart. The ventricles are the part of the heart that are responsible for the pumping action to move blood throughout the body. Because of this, the muscles in the ventricles are much larger and thicker to do their job properly.

Answer 3

The heart's ventricles are stronger than the atria. They have to pump blood farther than the atria.

Answer 4

atria
