Preload increases contractility (correct)

Preload decreases contractility

Preload has no effect on contractility

Preload and contractility are unrelated

The pressure that the ventricular muscles must generate to overcome the higher pressure in the aorta

The pressure in the ventricles when they are full of blood (correct)

The pressure in the aorta when the ventricles are empty

The pressure in the ventricles when they are empty

The more the heart muscles stretch during diastole, the more forcefully they contract during systole (correct)

The more forcefully the heart muscles contract during systole, the more the heart muscles stretch during diastole

The more the heart muscles contract during systole, the more forcefully they stretch during diastole
