Question

Quizplus · Accepted Answer

Blood vessel diameter is the most significant source of blood flow resistance as it has the greatest influence on blood flow resistance according to the Poiseuille's law. Blood viscosity, total blood vessel length, and blood vessel type also contribute to blood flow resistance but to a lesser extent compared to blood vessel diameter.
