Igcse Model Questions Vol1 2022 Biology Question 30
Practice objective / multiple choice question 30 from the 2022 Igcse Model Questions Vol1 Biology examination.
According to Poiseuille's law, for laminar flow the volumetric flow rate \(Q\) through a cylindrical vessel is proportional to the fourth power of its radius \(r\) (all other factors being equal). Artery A has a radius of \(2\) mm and carries blood at a flow rate of \(8\) mL s\(^{-1}\). Artery B has a radius of \(1\) mm and is subject to the same pressure gradient as artery A. What is the expected flow rate through artery B (in mL s\(^{-1}\))? Give your answer to one decimal place.
