The structure of the heart is what makes it an efficient pump. It works continuously without tiring, and it receives electric signals every second and pumps blood nonstop.
The heart is a muscle.
The left and right ventricles, which when they contract pump blood into the systemic and pulmonary curcuits.
The phrase "does the heart affected" makes no sense.
It makes the heart pump slightly faster
Veins do not pump, they are passive. They carry blood back to the heart which is the pump.

No, the other pump in the heart does not move blood from the atria into the ventricles. Instead, the atria receive blood returning to the heart, and they contract to push blood into the ventricles. The ventricles then pump blood out of the heart to the lungs and the rest of the body. This coordinated action ensures efficient blood circulation.
Absolutely - since the heart is the pump that makes the circulatory system work !
