Read the statements and choose incorrect one:
The valves in the heart allows the flow of blood only in one direction, i.e., from the atria to the ventricles and from the ventricles to the pulmonary artery or aorta.
The atrium and the ventricle of the same side are also separated by a thick fibrous tissue called the atrio-ventricular septum.
AV bundle continues from the AVN which passes through the atrio-ventricular septa to emerge on the left of the inter-ventricular septum and immediately divides into a right and left bundle.
This sequential event in the heart which is cyclically repeated is called the cardiac cycle a
Statement 1: AV node delays the impulses to heart apex approx for about 0.1 sec as it allowed the atria to empty completely.
