The function of the atrium

• To collect blood

• To pump blood to the lungs

• To pump blood into systemic circulation

• To pump blood to the heart muscle

The entrance to the ascending aorta is guarded by

• an atrioventricular valve

• bicuspid valve

• semilunar valve

• tricuspid valve

The only time when all of the valves in the heart are close is during

• ventricular diastole

• isovolumetric contraction

• artrial systole

• isovolumetric diastole

The opening of semilunar valves is due to

• increased ventricular pressure

• decrease ventricular pressure

• increased aortic pressure

• increase in artrial volume

If ventricular pressure is low, what will happen to the arterioventricular valves?

• close

• open

Aortic pressure at its peak during

• arterial systole

• isovolumetric contraction

• ventricular ejection

• isovolumetric relaxation

Which component of ECG cycle shows ventricular depolarisation?

• P

• QRS

• T

• U

In the diagram below, which part of the tracing represents the contraction of the atria?

• P

• T

• R

• S
