Q. A specialised nodal tissue embedded in the lower corner of the right atrium, close to atrio-ventricular septum, delays the spreading of impulses to heart apex for about $0.1 \,\sec$. The delay allows

Body Fluids and Circulation

Solution:

Atrio-Ventricular Node (AVN) present in the lower corner of the right atrium, delays the spreading of impulses to heart ventricles for about $0.1$ second. This pause allows the atria to empty completely into the ventricles before the ventricles pump out the blood.
