Vedclass · Answer

(D) The specialised nodal tissue described is the Atrioventricular Node $(AVN)$.It is located in the lower left corner of the right atrium near the atrioventricular septum.The $AVN$ delays the electrical impulse generated by the Sinoatrial Node $(SAN)$ by approximately $0.1 \; sec$.This delay is crucial because it ensures that the atria complete their contraction (atrial systole) and pump their blood into the ventricles before the ventricles begin to contract.Therefore,this delay allows the atria to empty completely into the ventricles.

$A$ specialised nodal tissue embedded in the lower corner of the right atrium,close to the atrioventricular septum,delays the spreading of impulses to the heart apex for about $0.1 \; sec$. This delay allows:
