Question: What effect does increasing the diameter of a blood vessel have on blood flow?

Options:

Correct Answer: Increases flow

Solution:

Increasing the diameter of a blood vessel decreases resistance, thereby increasing blood flow according to Poiseuille\'s law.

What effect does increasing the diameter of a blood vessel have on blood flow?

What effect does increasing the diameter of a blood vessel have on blood flow?

Step 1: Understand that blood vessels carry blood throughout the body.
Step 2: Know that the diameter of a blood vessel is how wide it is.
Step 3: Realize that when the diameter increases, the space inside the blood vessel gets larger.
Step 4: Remember that larger space means there is less resistance to blood flow.
Step 5: Understand that less resistance allows blood to flow more easily.
Step 6: Conclude that increasing the diameter of a blood vessel leads to an increase in blood flow.

Blood Flow Dynamics – Understanding how changes in blood vessel diameter affect resistance and flow rate.
Poiseuille's Law – A principle that describes the relationship between the radius of a vessel, resistance, and flow rate.
