Video Summary
Resistance to blood flow refers to the opposition that the circulatory system presents to the flow of blood. It plays a critical role in regulating blood pressure and blood flow to different organs and tissues. This resistance is directly proportional to blood viscosity (η) and the blood vessel's length (L); and inversely proportional to the radius of the vessel (r). This resistance (R) is represented as R=8Lr4
