Question

Make the correct pairs:

Column–I Time	Column–II Process
P	0.40 sec	(i)	Blood of atrium flows into ventricle
Q	0.10 sec	(ii)	Blood of ventricle flows into truncus arterious
R	0.30 sec	(iii)	Phase of atrium and ventricle systole
S	0.80 sec	(iv)	Total time of one cardiac cycle

• A. P–(iii), Q–(i), R–(iv), S–(ii)
• B. P–(iii), Q–(i), R–(ii), S–(iv)
• C. P–(iii), Q–(ii), R–(i), S–(iv)
• D. P–(i), Q–(iii), R–(ii), S–(iv)

Answer 1
