If an atheroma reduces the diameter of an artery from 2 mm to 1 mm, what effect would this have on the blood flow through the artery? (According to Poiseuille’s law, volume flow rate through a blood vessel is proportional to its radius to the fourth power i.e. V ∝ R4 ). A. blood flow would decrease to half (1/2) the value for an artery with diameter 2 mm. B. blood flow would decrease to a quarter (1/4) of the value for an artery with diameter 2 mm. C. blood flow would decrease to an eighth (1/8) of the value for an artery with diameter 2 mm. D. blood flow would decrease to one sixteenth (1/16) of the value for an artery with diameter 2 mm.
Option D. Blood flow would decrease to one sixteenth (1/16) of the value for an artery with diameter 2 mm.
