The figure shows the human heart: LA = left auricle, LV = left ventricle, RA = right auricle, RV = right ventricle. Positions 1 and 6 are at vessels entering the atria; 2 and 5 are at atrioventricular openings; 3 and 4 are at ventricular arterial outlets. Where are the valves located?
RRB Group-D

2022
✓ Answer:CAt positions 2, 3, 4 and 5
The mitral and tricuspid valves lie between atria and ventricles. The aortic and pulmonary valves lie at ventricular outlets. These correspond to positions 2, 3, 4 and 5.
697
Which of the following elements is part of heme (haem) of human blood?
RRB NTPC (Stage-II)
