Question

multiple choice question which of the following best describes a vascular spasm? a short - lived mechanism in which the damaged vessel dilates, increasing blood flow and the amount of clotting agents at the site of the injury a response of a capillary network to changing carbon dioxide levels a short - lived mechanism in which a damaged vessel narrows to minimize blood loss a long - term mechanism that triggers fibrin production need help? review these concept resources.

Explanation:

A vascular spasm is a short - lived response where a damaged blood vessel constricts (narrows) to reduce blood loss. The first option describes dilation which is incorrect. The second option is about capillary network and carbon - dioxide levels which is not related. The fourth option is about a long - term mechanism for fibrin production which is not a vascular spasm.

Answer:

A short - lived mechanism in which a damaged vessel narrows to minimize blood loss
