Which of the following increases turbulence in blood flow ?
Correct answer: D. Increase in diameter of blood vessel
- A. Reynolds number < 2000
- B. Decrease in velocity of blood
- C. Decrease in density of blood
- D. Increase in diameter of blood vessel
Explanation
Reynolds number rises with increasing blood velocity, density, and vessel diameter, making turbulent flow more likely. A Reynolds number below 2000 and reduced velocity favour laminar flow.
