The mechanics of blood flow in the body follows the laws offluid dynamics for tubes with a constant diameter and length. Whichstatement is correct?
The flow of fluid in a tube depends upon the absolute pressureat the beginning of the tube. The rate of fluid flow in a tube willdecrease if the pressure at the beginning is increased while thepressure at the end of the tube stays the same. The greater theresistance to flow in a tube, the greater the rate of flow for anygiven pressure difference. If both the resistance and the pressuregradient in a tube increases, the fow must also increase. The rateof flow in a tube will decrease if the resistance to flow isincreased.
