The typical ’lub-dub’ sounds heard during heartbeat are produced due to:
The typical ’lub-dub’ sounds heard during heartbeat are produced due to:
Show Hint
Heart sounds provide vital clues about the functioning of heart valves.
Updated On: Dec 26, 2024
- Closure of semilunar valves
- Closure of bicuspid and tricuspid valves
- Closure of bicuspid and tricuspid valves followed by semilunar valves
- Opening of bicuspid and tricuspid valves followed by semilunar valves
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The “lub” sound is produced by the closure of atrioventricular (bicuspid and tricuspid) valves during ventricular contraction.
The “dub” sound occurs due to the closure of semilunar valves during ventricular relaxation.
These sounds are critical indicators of heart valve health.
