| Primary Hemostasis – The Vascular System Our blood circulates freely through undamaged, intact vessels. The design of the vasculature, or blood vessels, is such that the walls of the vessels are chemically inert to both coagulation factors and platelets under normal conditions. Damage to a vessel breaks that inert epithelial lining, exposing the subendothelium and collagen, and releasing chemical signals that trigger subsequent hemostatic mechanisms. | View Page |
| Primary Hemostasis – Platelet Function Platelets have three primary functions: Maintenance of Vascular Integrity – Platelets contain chemicals within their granules that are vital to the normal growth and maintenance of the vascular system. Platelet Plug Formation – Platelets are the fundamental components of the physical barrier that initially fills the breach in the compromised vessel. Stabilization of the Platelet Plug – Inherent platelet stickiness acts as a strong bond between the platelet and the exposed subendothelium, as well as between platelets themselves. Fibrin strands will weave in amongst the bound platelets that make up the platelet plug, further compressing and solidifying the structure and creating a fibrin clot. | View Page |
