A)

What is the apparent viscosity (Pas) of blood that is experiencing a shear rate of 52 s^-1? Assume the blood has a yield stress of 0.005 pascals and a value of2 cP^1/2 for the parameter.

B) If this blood was flowing in 100-micron arteriole, explain how you would calculate the apparent viscosity of the blood.

Total peripheral resistance depends on which TWO factors?

(1) An arteriole undergoes vasomotion andshrinks from 4 mm in diameter to 2 mm. If MAP remains the same, theflow of blood will drop by what percentage?

(2)_________has themost important effect on blood flow through the capillarybeds.

a.Bloodviscosity

b.Vesselradius

c.Bloodosmolarity

d.Hematocrit

e.Vessellength

Using Poiseuille’s Law, explain how each factor (resistance, radius, length, viscosity) is related to blood flow. (No calculations… just understand how each one effects the other.)
