atrioventricular node (AV node)
The conduction starts at the pacemaker region called the Sinoatrial Node (SA node) which is just under where the superior vena cava enters the right atrium. From here the conduction passes to the Atrioventricular Node (AV node) which is just ot the right of the septum. From here the stimulation is passed through the Bundle of His which carries the conduction to the septum where two Bundle Branches pick it up. These branches carry the conduction to the base of the septum where they sperate into the Purkinje Fibres. These fibres carry the conduction all around the heart.
The atrioventricular (AV) node which is located in the right atrium. From there is travels down the septum, also called the atrioventricular bundle, and then spreads to all parts of the ventricles via the Purkinje fibers.
Inter-atrial septum
septum
The interatrial septum seperates the two upper chambers, namely the right atrium from the left atrium. It is the interventricular septum which seperates the lower chambers, namely the right ventricle from the left ventricle.
the septum divides the teo ventricles of the heart.
The interatrial septum separates the left and right atria.
The interatrial septum separates the left atrium from the right atrium (the atria are the upper chambers of the heart).
Fossa ovalis
The wall of muscle separating the right and left atria is the interatrial septum. The interventricular septum separates the right and left ventricles.
The septum is located between the left and right ventricles.
No. The heart is actually divided into four sections. They are the left atrium, right atrium, left ventricle, and finally the right ventricle.
