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 node triggers an im pulse that causes both atria to?
the atriventriculart node causes both atria to contract
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.
Atrioventricular node at the bottom of the?

Once a muscle action potential is initiated by the SA node where does the impulse spread?
It then spreads to both the right and left atria, then to the AV node, then down the bundle of His to the Purkinje fibers where it spreads to both the left and right ventricles.
Impulse refers to both force and?
Impulse refers to both force and time....... Impulse=(the change in Force)*(time) OR Impulse=the change in Momentum
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.
When the force and time of contact are halved the impulse on an object is?
The impulse on an object will be reduced by half when both the force and the time of contact are halved. Impulse is the product of force and time, so decreasing both will result in a proportional decrease in the impulse.
What is the P wave of electrocardiogram closely followed by?
Contraction of both atria
What are function of SA nodes?
There is only one SA(sinoatrial) node. It is located by the right atrium of the heart. it initiates the nerve impulse which travels through both atria to initiate atrial contraction. Then the impulse travels to the AV(atrial ventricular) node. the nerve impulse travels through the intraventricular septum to the apex of the heart, where it initiates the contraction of the ventricles(starting from the apex and squeezing the blood up and out of the arteries).
Is impulse function is an energy signal or a power signal or both Explain?
it can not be both!
