What else can I help you with?
When atria relax ventricles do what?
When relaxed, the atria expand, and then the ventricles contract.
Do atria contract before the ventricles?
Yes, atria contracts before the ventricles.
What difference atria and ventricles fetal pig?
the difference between the ventricles and the atria is that the ventricles are thicker
Why is the atria so thin walled?
Atria don't do nearly the same amount of work of contraction as do the ventricles. They are therefore relatively thin walled. Most of the blood that flows from the atria to the ventricles flows passively, and so the atria function mostly as a reservoir for blood volume.

Are ventricles superior?
In the context of the heart, the ventricles are not considered superior; they are actually located inferior to the atria. The atria are positioned above the ventricles, receiving blood from the body and lungs before it is pumped into the ventricles. Therefore, in anatomical terms, the atria are superior to the ventricles.
What do the atria do at the same time?
The atria contract simultaneously to push blood into the ventricles. This coordinated contraction ensures efficient filling of the ventricles with blood before they contract to pump blood out to the rest of the body.
What part of the blood is atria and ventricles?
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.
Function of atria?
ventricles
Why would it be bad if the atria and ventricles were in systole at the same time?
please help me with this question
Why have the ventricles got thicker walls then the atria?
atria are just the receiving chambers, it is the ventricles that actually pump the blood into the pulmonary and systemic circuits
What makes the valves between atriums open and close?
There are no valves between the atria. The valves between the atria and ventricles close when the ventricles contract.
