Question

Poiseuille's Law, as applied to blood flow, highlights a critical design consideration for vascular implants. What is the most significant impact of small changes in vessel radius on blood flow, and what condition does this help explain?
Options
A Small changes in radius cause minor flow changes, explaining hypotension.
B Small changes in radius cause huge changes in flow, explaining hypertension.
Correct Answer
C Vessel radius only affects pressure, not flow.
D Viscosity is the only factor affecting flow in stents.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The document, under the description of Poiseuille's Law, clearly states: "Small changes in vessel radius cause huge changes in flow. Explains hypertension." This is due to the r⁴ term in the formula.

Hint

Recall the 'r⁴' term in Poiseuille's Law and its implication on flow when the radius changes.
