1- Which change in a parameter (A or B, below) would cause a greater increase in resistance to blood flow through
a blood vessel? Chose the correct response and explain briefly (equations are nice; define your parameters [e.g., R = resistance]). A. An increase in blood viscosity by a factor of 2. B. A reduction in vessel radius by a factor of 2.
Option B is the right answer, because: Vessel resistance (R) is directly proportional to the length (L) of the vessel and... View the full answer
