1. | 3 → 1 → 4 → 2 | 2. | 2 → 3 → 1 → 4 |
3. | 1 → 3 → 4 → 2 | 4. | 4 → 2 → 1 → 3 |
The correct statements amongst the following are:
I: | Cardiac output is volume of blood pumped by each ventricle per minute |
II: | All the four chambers of human heart are never in diastole together |
III: | The first heart sound is associated with opening of atrioventricular valves |
IV: | The pressure in pulmonary artery is equal to the pressure in aorta |
1. | Only I | 2. | Only I and IV |
3. | Only I and III | 4. | Only I, II and IV |
What would be the heart rate of a person if the cardiac output is 5L, blood volume in the ventricles at the end of diastole is 100 mL and at the end of ventricular systole is 50 mL?
1. | 125 beats per minute | 2. | 50 beats per minute |
3. | 75 beats per minute | 4. | 100 beats per minute |
If the heart rate is 60 per minute, the duration of each cardiac cycle will be:
1. | 0.8 seconds | 2. | 0.75 seconds |
3. | 1.0 second | 4. | 1.2 second |
