Question

If the strength of ventricular contraction increases then it will cause

Answer 1

The ventricles of the heart pump the blood into the aorta (left ventricle) and pulmonary artery ( right)

if the strength of ventricular contraction increases :

More blood is pumped out of the heart

The blood pressure increases

Blood supply to the body organs increases

More oxygen exchange takes place in the lung

But also,

more energy ( ATP) is taken up by the cardiac muscles when their strength of contraction increases
