Diastolic blood pressure

Vedclass · Answer

(B) The viscosity of blood refers to the thickness or resistance to flow of the blood. It plays a crucial role in determining the peripheral resistance of blood flow through the blood vessels. Increased peripheral resistance directly influences the pressure exerted on the arterial walls,particularly during the relaxation phase of the heart,which is the diastolic blood pressure. Therefore,blood viscosity is a key factor in maintaining diastolic blood pressure.
