Text Solution
Verified by ExpertsThe correct answer is:
A
To match the items in Column-I with those in Column-II, we need to analyze each item:
After analyzing all connections based on their functions and characteristics, we find the matches: A-(r), B-(p), C-(q), D-(s). Thus, the correct combination is Option A.
- A. The chordae tendineae are fibrous cords that attach to the atrioventricular (AV) valves in the heart, which control blood flow from the atria to the ventricles. They are linked to the closure of the AV valves during ventricular contraction. This corresponds to (r), which is associated with the closure of the valves.
- B. The AV node is located in the heart and is responsible for conduction between the atria and ventricles. It plays a crucial role in heart rhythm and corresponds to the (p) option, as it is linked to the right atrium.
- C. The second heart sound occurs due to the closure of the aortic and pulmonary valves at the end of ventricular contraction. This matches with (q).
- D. The SA node, known as the pacemaker of the heart, initiates the heartbeat and corresponds with (s), describing the heart strings or structures that signal the start of heart contractions.
After analyzing all connections based on their functions and characteristics, we find the matches: A-(r), B-(p), C-(q), D-(s). Thus, the correct combination is Option A.
