1. Plasma minus its clotting proteins is call________.

Serum

2. _______ is the consolidation or tightening of the fibrin clot that helps to bring the edges of a damaged vessel closer together.

clot retraction

3. Hemoglobin functions in transporting both oxygen and carbon dioxide and in regulating blood pressure.

true

4. The most numerous white blood cells in a differential WBC count of a healthy individual are the neutrophils.

True

5. Which of the following are NOT required for clot formation?(1)vitamin K (2)calcium (3)prostacyclin (4)plasmin (5)fibrinogen

e. 3 an 4

6. What are the steps of hemostasis in order?

(1) Vascular spasm(2) Adhesion and aggregation of platelets on damaged vessel(3) Prothrombinase formed by extrinsic or intrinsic pathway(4) Conversion of prothrombin into thrombin(5) Conversion of fibrinogen into fibrin

7. Explain why RBCs are highly specialized for oxygen transport?

b. RBCs contain hemoglobin and lack a nucleus. Their biconcave shape provides a large surface area for the inward and outward diffusion of gas molecules. RBCs can carry up to four oxygen molecules for each hemoglobin molecule.

8. Which of the following are true?

c. White blood cells leave the bloodstream by emigration. Adhesion molecules help white blood cells stick to the endothelium, which aids in emigration. Neutrophils and macrophages are active in phagocytosis. The attraction of phagocytes to microbes and inflamed tissue is termed chemotaxis.

9. A person with A- blood can receive a blood transfusion from which of the following types?(1)A+ (2)B- (3)AB- (4)O- (5)A-

d. 4 and 5

10. A person with type B+ blood receives a transfusion of type AB+ blood. What will happen?

a. The recipients antibodies will react with the donors red blood cells

11. What happens to iron that is released during the breakdown of damaged red blood cells?

(d) It attaches to transferrin and is transported to bone marrow for use in hemoglobin synthesis.

12. Which of the following would not cause an increase in erythropoietin?(1) anemia (b) high altitude (c) hemorrhage (d) donating blood (e) polycethymia

e.

13. Match the following:

(a) the percentage of total blood volume occupied by red blood cells (4) hematocrit(b) the percentage of each type of white blood cell (7) differential white blood cell count(c) measures numbers of RBCs, WBCs, platelets per u of blood; hematocrit; and differential WBC count (6) complete blood count(d) measures the rate of erythropoiesis (1) reticulocyte count(e) withdrawal of blood from a vein using a needle and collecting tube (3) venipuncture(f) withdrawal of a small amount of red bone marrow with a fine needle and syringe (5) bone marrow aspiration(g) removal of a core of red bone marrow with a large needle (2) bone marrow biopsy

14. Match the following:

(a) contain hemoglobin and function in gas transport (4) Red blood cells(b) cell fragments enclosed by a piece of the cell membrane of megakaryocytic; contain clotting factors (6) platelets(c) white blood cell showing a kidney-shaped nucleus; capable of phagocytosis (2) monocytes(d) monocytes that roam the tissues and gather at sites of infection or inflammation (7) wandering macrophages(e) occur as B cells, T cells, and natural killer cells (1) lymphocytes(f) give rise to red blood cells, monocytes, neutrophils, eosinophils, basophils, and platelets (5) myeloid stem cells(g) give rise to all the formed elements of blood; derived from mesenchyme (3) pluripotent stem cells

15. Match the following:

(a)tissue protein that leaks into the blood from cells outside blood vessels and initiates the formation of prothrombinase (4) thromboplastin (b) an anticoagulant (6) heparin(c) its formation is initiated by either the extrinsic or intrinsic pathway or both; catalyzes the conversion of prothrombin to thrombin (1) prothrombinase(d) forms the threads of a clot; produced from fibrinogen (3) fibrin(e) can dissolve a clot by digesting fibrin threads (5) plasmin(f) serves as the catalyst to form fibrin; formed from prothrombin (2) thrombin
