Blood vessels can
Open in App
Solution
The correct option is C Both contract and expand
The force that blood exerts against the wall of a vessel is called blood pressure. This
pressure is much greater in arteries than in veins. The pressure of blood inside the
artery during ventricular systole (contraction) is called systolic pressure and pressure
in artery during ventricular diastole (relaxation) is called diastolic pressure.
Thus, the correct option is C.
