The blood pressure exerted on the wall of any blood vessel when the ventricle is contracted is the ________, and the pressure exerted on the wall of any vessel when the heart is relaxed is the ________.

Options

A. systolic pressure, diastolic pressure
B. diastolic pressure, systolic pressure
C. sphygmomanomic pressure, blood pressure
D. ventricular pressure, auricular pressure.

Answer

To answer the question, we need to identify two types of blood pressure related to the heart's activity:

1. **Systolic Pressure**: This is the pressure exerted on the walls of the blood vessels when the ventricles of the heart contract. During this phase, blood is pumped out of the heart into the arteries, creating a peak pressure in the arteries.

2. **Diastolic Pressure**: This is the pressure exerted on the walls of the blood vessels when the heart is in a relaxed state, specifically when the ventricles are filling with blood. During this phase, there is less pressure in the arteries as the heart is not actively pumping blood.

Putting this information together, we can fill in the blanks in the question:

The blood pressure exerted on the wall of any blood vessel when the ventricle is contracted is the **systolic pressure**, and the pressure exerted on the wall of any vessel when the heart is relaxed is the **diastolic pressure**.

### Final Answer:
The blood pressure exerted on the wall of any blood vessel when the ventricle is contracted is the **systolic pressure**, and the pressure exerted on the wall of any vessel when the heart is relaxed is the **diastolic pressure**.
