Allowing the lining of the vessels to become impermeable

Dilating blood vessels

Answer and Explanation

The Correct Answer is B

A. The vascular response initially increases permeability to allow essential cells and substances to reach the site of injury, rather than becoming impermeable.

B. Dilating blood vessels increases blood flow to the injured area, facilitating the delivery of immune cells and nutrients necessary for healing.

C. Limited perfusion contradicts the purpose of the vascular response, which is to enhance blood flow to the injury.

D. While blood vessels can constrict initially to minimize blood loss, the vascular response overall is characterized by dilation to promote healing.
