Aorta Wall Ventricle Heart Pressure Relaxes Thickness Time

The aorta wall stretches when the ventricle contracts, increasing blood pressure, and recoils when the ventricle relaxes, decreasing pressure. This action maintains a smooth and consistent blood flow.

The aorta wall stretches when the ventricle contracts, increasing blood pressure, and recoils when the ventricle relaxes, decreasing pressure. This action maintains a smooth and consistent blood flow.

Front The thickness of the aorta wall changes all the time during each cardiac cycle. Explain why ( 3 marks)
Back (Aorta wall) stretches;

Because ventricle / heart contracts / systole / pressure increases;

(Aorta wall) recoils;

Because ventricle relaxes / heart relaxes / diastole / pressure falls;

Maintain smooth flow / pressure;
