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.
The SA node triggers an impulse that causes both atria to do what?
SA node sends an impulse for the atria to contract. AV node is then activated which contracts the ventricles.
What produces the pulse rate?
Both atria and ventricles contracts rythmically to propagate blood forward. Contraction of the left ventrical forces the boold in systemic circulation. The wave of arterial dilatation moves forward across the arterial system to produce pulse.
What do the atria do at the same time?
Both atria open and close simultaneously.
Where does the atria located?
The Heart's own pace makerThe heart beats regularly because it has it's own pacemaker. The pacemaker is a small region of muscle called the sinoatrial, or SA, node. It is in the upper back wall of the right atrium. The node triggers an impulse that causes both atrium to contract. Very quickly, the impulse reaches the atrioventricular, or AV, node at the bottom of the right atrium. Immediately, the atrioventricular node triggers an impulse that causes both ventricles to contract.
What do both atria do at the same time?
They both contract at the same time.
What do both atria empty into?
I am not sure, but i think they empty into the chambers.
What cells stimulate both atria to contract?
Nodal or pacemaker cells.
What is the P wave of electrocardiogram closely followed by?
Contraction of both atria
How do the 5 senses affect your pulse?
What we see can excite or calm, raising or lowering the pulse rate. What we hear can be upsetting (ex. a loved one had an accident) or pleasing (I love you). If sensitive to odors, a person could be triggered by a smell that causes an asthma attack which then increases pulse rate. Painful stimuli raise pulse and blood pressure; a massage can lower both.

Which part of the heart recives blood?
both the right and left atria receive blood.
