What is Pulse pressure in a paicular vessel is determined chiefly by and explain in detail?
In advancing age due to loss in elasticity of blood vessels, stretching decreases which results in increased pressure during systole with normal diastolic blood pressure (systolic hypeension). The blood vessels behave like a rigid tube. It is characterized by high pulse pressure. Pulse pressure is determined by elasticity of vessel wall that varies inversely with total peripheral resistance.
