a) As blood flows from the aorta to the arteries, arterioles, and capillaries and through the venous circulation, it encounters various resistances to flow, which results in pressure drops. Calculate the resistance for an artery and a capillary using the following dimensions. (4 pts) Aorta: D=2.5 cm, L=40 cm Capillary: D= 8 m, L=1mm b) What does a systemic blood pressure of 120/80 mmHg mean? What is the pressure converted in SI unit? (pHg=13.6 g/cm) (2 pts) c) Estimate the change in hydrostatic pressure within a blood vessel near the ankle when a 6-ft person changes from a lying to a standing position? (1 ft = 30.48 cm, density of blood pblood= 1060 kg/m, g=9.8 m/s2) (2 pts) %3!
