Events that occur during hemostasis...
- The vessels constrict to reduce blood flow.
- Platelets stick to the vessel wall around the injury.
- Enzymatic reactions occur involving coagulating proteins.
- Fibrin is then produced to form a hemostatic plug.
What is hemophilia and how is it treated?
- What is it?
- A condition in which the blood doesn't clot properly to make a person bleed excessively. Could become severe even from a slight cut.
-Clotting factor concentrations
--- Made from human blood
--- Blood is treated to prevent the spread
-Recombinant clotting factor
--- Are not made form human blood
--- Typically given to children
