Question

multiple choice question
vasoactive chemicals are substances that stimulate which of the following?
coagulation
agglutination
fibrinolysis
erythropoiesis
vasomotion

Explanation:

Vasoactive chemicals act on blood vessels. Vasomotion refers to the contraction and relaxation of blood vessel smooth muscle, which is stimulated by vasoactive substances. Coagulation is blood clotting, agglutination is clumping, fibrinolysis is clot breakdown, and erythropoiesis is red blood cell production—none relate to vessel stimulation like vasomotion.

Answer:

E. Vasomotion
