Study Notes
- Hemostasis occurs in the sequence of vascular spasm, platelet plug formation, and coagulation.
- The final step in clot formation is fibrinogen converting into fibrin.
- Platelets form a temporary plug at the site of bleeding.
- Blood group O has both anti-A and anti-B antibodies.
- The extrinsic pathway of blood clotting is triggered by tissue factor.
- Heparin inhibits coagulation.
- Blood type is determined by glycoproteins present on the surface of erythrocytes.
- Thrombin converts fibrinogen to fibrin.
- A person with type AB blood would have type A and B agglutinogens (RBC antigens).
- Platelets are derived from megakaryocytes.
- Tissue factor (TFIII), or tissue thromboplastin, triggers the "shortcut" extrinsic mechanism that bypasses several steps of the intrinsic pathway.
- Prothrombin activator generates thrombin.
- Neither anti-A nor anti-B antibodies are found in the serum of a person with AB blood.
- Serum is plasma minus the clotting proteins.
- Erythroblastosis fetalis is caused by an Rh incompatibility between an Rh-negative mother and her Rh-positive baby during pregnancy.
- Eighty-five percent of Americans carry the D Rh agglutinogen on their red blood cells (RBCs).
- A person with type A blood would make antibodies to the B agglutinogen but not the A agglutinogen.
- Blood group B has only anti-A antibody.
- The event of hemostasis indicated by "C" is coagulation.
- Platelet-derived growth factor stimulates blood vessel healing.
- Blood group A has only antigen A.
- The event of hemostasis indicated by "A" is vascular spasm.
- Ringer's solution as a plasma expander would be associated with the least complications.
- Platelets are derived from megakaryocytes in bone marrow.
- Blood group AB has both antigens A and B.
- Basophil granules contain the anticoagulant, heparin.
- Von Willebrand factor (VWF) assists platelets to adhere to collagen fibers.
- A person with type O blood would make antibodies to the A and B agglutinogens.
- The event of hemostasis indicated by "B" is platelet plug information.
- A person with type B blood would make antibodies to the A agglutinogen but not the B agglutinogen.
- Platelets are not complete cells, but fragments of cells and are very small compared to other cellular components
- Blood group AB has both antigens A and B.
- A person with type AB blood would have type A and B agglutinogens (RBC antigens)

Description
Explore hemostasis, the process of blood clotting, including vascular spasm, platelet plug formation, and coagulation. This includes the roles of fibrin, platelets, blood groups, and the extrinsic pathway. Also covered are anticoagulants like heparin, blood type determination, and the functions of thrombin and prothrombin activator.
