Question

match the definition with the appropriate hemostasis pathway.

1. begins with chemicals that are outside of the blood.
2. activated with the interaction of thromboplastin and factor vii.
3. begins with chemicals that are inside the blood.
4. activated when factor xii comes into contact with collagen.
5. utilizes plasma factors viii, ix, xi, and xii.
6. begins with activated factor x.
7. utilizes factor v, calcium, and prothrombinase.
8. continues with the conversion of fibrinogen into fibrin.

Explanation:

1. The extrinsic pathway begins with chemicals outside the blood.
2. The extrinsic pathway is activated by the interaction of thromboplastin and factor VII.
3. The intrinsic pathway begins with chemicals inside the blood.
4. The intrinsic pathway is activated when factor XII contacts collagen.
5. The intrinsic pathway utilizes plasma factors VIII, IX, XI, and XII.
6. The common pathway begins with activated factor X.
7. The common pathway utilizes factor V, calcium, and prothrombinase.
8. The common pathway continues with the conversion of fibrinogen into fibrin.
