Unclogging Arteries
Research done in the 1930s by the French physiologist Jean Poiseuille showed that the resistance R of a blood vessel of length l and radius r is
R =
kl |
r4 |
,
where k is a constant. Suppose a dose of the drug TPA increases r by 5%. How will this affect the resistance R? Assume that l is constant.
