The first heart sound is heard during:
| 1. | beginning of ventricular systole |
| 2. | end of ventricular systole |
| 3. | atrial systole |
| 4. | ventricular ejection |
Match each item in Column I with one in Column II and select the correct answer from the codes given:
| Column I | Column II | ||
| A. | Mitral valve | a. | Allows blood flow from left atrium to left ventricle |
| B. | Papillary muscles | b. | Does not allow back opening of AV valves during ventricular systole |
| C. | AV node | c. | Ensure all chambers do not contract simultaneously |
| D. | Fibrous band between atrial and ventricular muscle mass | d. | Ensures atria contract before ventricles |
Codes
| A | B | C | D | |
| 1. | a | b | c | d |
| 2. | b | a | c | d |
| 3. | b | a | d | c |
