36. Complete the following paragraph about the Blood Clotting by writing the missing terms in the answer
blanks using the answer choices below.
erythrocytes
fibrin
fibrinogen
platelets
prothrombin
serotonin
thrombin
Clotting begins when a break occurs in a blood vessel wall. Almost immediately, __________________
cling to the blood vessel wall and release _________________________ which helps to decrease blood
loss by constricting the vessel. Prothombin activator in the platelet causes ______________________ to
be converted into ______________________. Once present, thrombin acts as an enzyme to attach
_________________________ molecules together to form long, threadlike strands of
_________________________, which then traps _________________________ flowing by in the blood.
