Answers

Answer 1

Answer:

B. It constricts the wound area prior to fibrin formation.

Explanation:

Answer 2

Before the formation of fibrin, vascular spasm constricts the wound area.

Vascular spasm

It is the narrowing of the arteries resulting due to persistent contraction of the blood vessels, also called vasoconstriction.

This can diminish the flow of blood, this can influence any part of the body.

Vascular spasm or vasoconstriction is one of the steps of hemostasis.

It is a brief reflexive contraction at the time of hemostasis, which makes a decrease in the flow of blood to the region.

This takes place just prior to the formation of platelet plug by fibrin.

The formation of platelet plug takes place directly after the rupturing of blood vessel takes place.

After some minutes, the formation of platelet plug takes place completely by fibrin.

Thus, the correct answer is option B.
