Vascular spasm as a result of trauma to vessels minimizes blood loss by

Question

Quizplus · Accepted Answer

Vascular spasm following trauma to blood vessels helps minimize blood loss by both slowing blood flow through the vessels due to constriction and by pressing together the surfaces of the vessel, which promotes adhesion and sealing off the damaged area. This process can be influenced by sympathetic stimulation, which is part of the body's response to injury. Therefore, all the options provided contribute to the mechanism of vascular spasm in reducing blood loss.
