Document Summary
The blood flow to each organ is not the same and blood flow to every organ can vary from time to time: effect of pressure gradient. The pressure gradient along the length of the tube determines blood flow. Absolute pressure is not key to determining blood flow. When you have a higher-pressure gradient, you will have more blood flow. No matter how much the flow of blood is in two different arteries, if the delta p is the same the 2 arteries will have the same flow: effect of radius. Larger diameter tube exerts less resistance to flow with means more blood flow. Resistance is increased by tube length and viscosity of blood. Larger size tube means less resistance for blood to flow (blood will flow more quickly and get to the organs more quickly) 10 ml of blood is distributed differently in the different tubes and can add more blood into the organs.
