-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
You need more force to pump the blood to the lungs or the body than you do just to pump it to the next chamber. The atria pump to the ventricles. Easy. The ventricles need to pump the blood to the lungs (right ventricle) or the body (left ventricle) which calls for more pressure, hence a larger contraction wave.
what is the differences between nuclear energy and radiant energy
what are the differences between truncated square prism and frustrum cylinder
What are the differences between x-rays and gamma rays?
The Ventricles are bigger and rougher than the AtriumsThe Ventricles are bigger and rougher than the Atriums.sizeshapewall thickness
the difference between the ventricles and the atria is that the ventricles are thicker
There are no valves between the atria. The valves between the atria and ventricles close when the ventricles contract.
When relaxed, the atria expand, and then the ventricles contract.
The atrioventricular node and the bundle of HIS are the electrical conduction link between the atria and the ventricles.
Yes, atria contracts before the ventricles.
When the Aalves close between the Ventricles and the Artery what sounfd does it make.
Annulus fibrosus cordis
when the ventricles closes and between the atria and the ventricles.
uricles are part of the atria and serve to increase the volume of the atria. The atria that they are a part of serve to direct blood into the ventricles and are not very muscular. The ventricles are far more muscular than the atria and serve to pump blood to either the lungs or the rest of the body ( the right and left ventricles respectively).
