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.
Why would it be bad if the atria and ventricles were in systole at the same time?
please help me with this question
What node triggers an im pulse that causes both atria to?
the atriventriculart node causes both atria to contract
Are atria and auricle the same?
yes
What Node that triggers an impulse that causes both atria?
The Sinoatrial Node sends a wave of electric impulses through the heart, which causes both atria to contract.
What chambers of the heart receives blood from the body?
Right atrium then right ventricle.
What do both atria empty into?
I am not sure, but i think they empty into the chambers.
Does atria have the same meaning as atrium?
Yes, "atria" is the plural form of "atrium." An atrium is a chamber of the heart that receives blood from the veins, while atria refers to the two upper chambers of the heart.
What is the P wave of electrocardiogram closely followed by?
Contraction of both atria
Why the atria walls so thin?
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.

What two chambers contract last in the heart?
During diastole the atria fills with blood.
