What function does platelets and fibrinogen have in common?

Platelets and fibrinogen both play essential roles in the process of hemostasis, which is the body's mechanism to stop bleeding. Platelets are small cell fragments that aggregate at the site of a blood vessel injury, forming a temporary plug. Fibrinogen is a soluble plasma protein that is converted into fibrin by the enzyme thrombin, forming a stable mesh that reinforces the platelet plug. Together, they work to form a clot that prevents further blood loss.
