Question

Which of the following factors would not increase peripheral resistance?

1) elevated hematocrit
2) vasodilation
3) increased sympathetic stimulation
4) elevated levels of epinephrine
5) irregularities in the vessel walls caused by plaques

Answer 1

Vasodilation is the factor that would not increase peripheral resistance because it actually decreases resistance to blood flow.

Step-by-step explanation:

The factor that would not increase peripheral resistance is vasodilation. Vasodilation refers to the widening of blood vessels, which actually decreases resistance to blood flow. Therefore, when blood vessels dilate, peripheral resistance decreases.
