Question

When two atria contract simultaneously and result in the blood pumping into ventricles this is called

• A. Arterial diastole
• B. Arterial systole
• C. Ventricular diastole
• D. Ventricular systole

Answer 1

The correct option is B

Arterial systole

Correct Option: b) Arterial systole

1. Arterial systole occurs when two atria contract at the same time. Blood is pumped into the ventricles during this phase mainly for the contraction of two ventricles.
2. Arterial systole is the constriction of the arterial walls and ejection of blood.

Incorrect options

a) Arterial diastole

Arterial diastole is the relief of the arterial walls and filling with blood.

c) Ventricular diastole

Ventricular diastole is the relaxation of cardiac muscles in two ventricles and filling with blood.

d) Ventricular systole

Ventricular systole is the constriction of cardiac muscles in two ventricles and the ejection of blood.

Arterial systole is the constriction of the arterial walls and ejection of blood.
