the atria
ventricles are the pumping chambers of the heart, so they have to be thicker and bigger to exert enough force to perform their function.
Atria is the receiving chamber and it is located at the top while ventricles are the one responsible for pumping blood out of the heart either to oxygenate the blood or to deliver it into our systems and it is located at the bottom part of the heart
The atria Actually, it is the contractions (squeezing) of the ventricles (the lower parts of the heart), not the atria (the upper parts), that do the pumping. That's why the lower part of the heart is larger, and the muscular walls are thicker. The atria receive the blood from the body and pump it down into the ventricles.
The wall of the ventricles is thicker than the walls of the atria as they have to be stronger as they have to pump the blood around the body where as the atria only have to pump blood into the ventricles

-the atriums are smaller then the ventricles. -the atriums have thinner muscle tissue. -the atriums only have to pump blod to the ventricles. -the ventricles are larger in size. -the ventricles have larger muscle tissue. -the ventricles have to pump blood to either the lungs or around to the rest of the body. hope this helpedddd ;D xox <3 Bellaaaa
The Atria and Ventricles are parts of the heart not the blood. The Atria is the upper chambers of the heart and the Ventricles are the lower chambers of the heart.
The ventricles are the lower chambers of the heart. The atria are the upper changes.
Cardiac Muscle or myocardium are the muscle that make up the heart that contract and relax to pump blood.
No. They are in the organ of the heart
