Answer:
First is True, Second is False.
Compare it to respiration in the human body or like how a car converts fuel to work or how a machine works because of electricity
Both use oxygen, both produce energy, both give out carbon dioxide as the result and the overall chemical reactions are the same.

<span>The ventricles are the part of the heart that are responsible for the pumping action to move blood throughout the body. Therefore, the muscles in the ventricles are much larger and thicker to do their job properly. The atrium only has to pump blood through an open valve (the tricuspid valve) into the right ventricle. There is much less resistance to this flow of blood so much less muscle is needed. </span>
