Explanation:
The sound of the heartbeat is produced by the closure of heart valves. The heart valves are responsible for ensuring that blood flows only in one direction. The sound of the heart is divided into two sounds. The first sound is a low-frequency, long-duration sound, and the second sound is a high-frequency, short-duration sound.
The first sound of the heartbeat is heard when the bicuspid and tricuspid valves close. These valves are located between the atria and ventricles. The closure of these valves causes the first sound of the heartbeat.
The second sound of the heartbeat is heard when the semilunar valves close. These valves are located between the ventricles and the great arteries. The closure of these valves causes the second sound of the heartbeat.
Therefore, the correct answer is option B - the first sound of the heartbeat is produced by the closing of the bicuspid and tricuspid valves.
