Summarize the relationship between the radius of a blood vessel and blood pressure
What will be an ideal response?
As the radius of a blood vessel increases, the resistance to blood flow decreases, and vice versa. Peripheral resistance is directly proportional to blood pressure. Thus, as resistance to blood flow decreases, blood pressure also decreases. Likewise, as resistance to blood flow increases, blood pressure also increases.
