What is the relationship between peripheral resistance and blood pressure?

Peripheral resistance and blood pressure have a directly proportional relationship. This means that as peripheral resistance increases, blood pressure also increases.

Peripheral resistance is the resistance to blood flow in the blood vessels. It is determined by several factors, including the diameter of the blood vessels, the viscosity of the blood, and the length of the blood vessels. When peripheral resistance increases, it means that the blood vessels are narrower or the blood is thicker, making it more difficult for the heart to pump blood through the body. As a result, the pressure of the blood against the walls of the blood vessels increases, leading to higher blood pressure.
