Platelets
Step 1 Vascular spasm
• Smooth muscle contracts,
causing vasoconstriction.
Collagen
fibers
Step 2 Platelet plug
formation
• Injury to lining of vessel
exposes collagen fibers;
platelets adhere.
• Platelets release chemicals
that make nearby platelets
sticky; platelet plug forms.
Platelets
Fibrin
Step 3 Coagulation
• Fibrin forms a mesh that traps
red blood cells and platelets,
forming the clot.
