Final answer:

Vessel radius significantly affects blood flow resistance.


Explanation:

Resistance in blood flow is influenced by factors such as vessel length, blood viscosity, and vessel radius, according to Poiseuille's equation. Of the options provided, the force of the ventricular contraction is not a factor in how resistance affects blood flow. Vessel radius plays a crucial role in determining resistance, as small changes in radius can greatly impact flow due to its exponent of 4 in the resistance equation.
