Answer 31

The complete heart beat from its generation to the beginning of the next beat. **The stages of the cardiac cycle:** 1. Diastole - Atrial contraction [ 0.1 ms ] 2. Systole - Ventrical contraction [ 0.3 ms ] 3. Intervenning - Atrial and Ventricular relaxation ( Complete cardiac diastole ) [ 0.4 ms ]

Question 32

How does the *Lub* sound of the heart beat is created?

Answer 32

Due to the closing of the bicuspid and the tricuspid valves.

Question 33

How does the *Dup* sound of the heart beat is created?

Answer 33

Due to the closing of the semi-lunar valves

Question 34

What is called the systolic blood pressure?

Answer 34

When the heart beats, it contracts and pushes the blood through the arteris to the rest of the body. This force createas a pressure on the arteries. This pressure is called the systolic blood pressure.

110-120 mmHg

Question 36

What is the normal diastolic blood pressure of a human?

Answer 37

70-80 mmHg

Question 38

What is the normal resting blood pressure of a human?

Answer 38

Blood pressure (B.P) = 120/80 mmHg
