AV node is biologically an inhibitor of the conduction across the atrium to ventricles. The conduction of impulse is delayed across the AV node. This buys time for the atria to contract, to be fallowed by ventricles.

What is the treatment when the AV and SA nodes fail?
The remedy for failure of the SA and AV nodes is a pacemaker.
Can someone hAVe 2 AV nodes?
yes
What are AV nodes biologically?
AV node is biologically an inhibitor of the conduction across the atrium to ventricles. The conduction of impulse is delayed across the AV node. This buys time for the atria to contract, to be fallowed by ventricles.
What is the cardioacceleratory center?
innervates SA and AV nodes, heart muscle, and coranary arteries through parasympathetic fibers in the vagus nerves
What if neither SA Node or the AV Node of the heart work?
If neither of the nodes work then the heart will be unable to contract its muscles to pump blood.
What is order for intrinsic conduction system in starting from the sa node?
sa nodes - av bundle- left bundle branches- purkinje fibers . hope this helps
What does the heart have that make sures the heart is beating at the right speed?
the SA and AV nodes in the heart produce electrical impulses that cause the heart muscle to contract or "beat", these nodes are controlled by the medulla and pons in the brain stem Excuse me but put it in a way that a 5th grader could understand. Thx
How the human heart is timed?
The rhythmic sequence of contractions is coordinated by the sinoatrial (SA) and atrioventricular (AV) nodes.
What is the function of a nodes?
There are a couple of different nodes in the body, and they refer to different things, but since your question is posted under cardiovascular health, you are probably referring to either lymph nodes or the heart's conduction system. Lymph nodes basically act as filters to clean the extracellular fluid before it reenters circulation, and is part of the immune system where white blood cells mature. There are also nodes like the sinoatrial node (SA) and the atrioventricular (AV) node. They are what act as pacemakers for your heart, driving the periodic electrical impulses that cause a heart beat.
Does the AV node initiates the contraction of the atria?
No, the sinoatrial (SA) node initiates contraction of the atria, which subsequently causes stimulation of the AV node, which then initiates contraction of the ventricles via the Purkinje fibers.
What are the names of the heart nodes?
The "nodes" in the heart are the sinoatrial, or SA, node, which is found in the R atrium and is considered the primary pacemaker of the heart. The atrioventricular node, or AV node, is located in the right atrium just above the medial leaflet of the tricuspid valve. It allows for the electrical impulses generated in the atrium to be transmitted to the ventricles and to cause ventricular contraction.
What component of the heart's conduction system is considered to be the heart's pacemaker?
Furkinje Fibers
