Pulse and Blood Pressure

Q.

How much amount of blood is pumped during each heartbeat?

1. 100 ml

2. 55 ml

3. 50 ml

4. 70 ml

Q.

Stroke volume is the amount of blood the left ventricle pumps out in one cardiac cycle. This is around 70ml. Now, to get the cardiac output, we have to multiply (i)__ with the normal heart rate of (ii)__ /min and we get (iii)__ ml/min. This means that in one minute, each ventricle of a normal heart pumps about (iv)__ litres of blood out.

1. (i) Stroke volume, (ii) 72, (iii) 5, 040, (iv) 5

2. (i) Total volume, (ii) 82, (iii)8, 200, (iv) 8

3. (i) Volume of the heart, (ii) 72, (iii)3, 720, (iv) 3

4. (i) Volume of the ventricles, (ii) 72, (iii)2, 600, (iv) 2

Q.

Define diastolic pressure.

Q.

Differentiate between the following:

Gestation and Parturition

Q. A normal systolic blood pressure is __(i)___ and a normal diastolic blood pressure is ___(ii)___.

1. (i) Diastolic pressure, (ii)Systolic pressure , (iii) 80 mmHg, (iv)120 mmHg

2. (i) Systolic pressure, (ii)Diastolic pressure, (iii)120 mmHg, (iv)80 mmHg

3. (i) Diastolic pressure, (ii) Systolic pressure, (iii)120 mmHg, (iv)80 mmHg

4. (i) Systolic pressure, (ii)Diastolic pressure, (iii)80 mmHg, (iv)120 mmHg
