Exercises: 6

1. Blood is composed of cells which include erythrocytes, leukocytes and

platelets.

2. Blood is composed of cells, suspended in clear, straw-colored liquid called

plasma.

3. All blood cells originate in the marrow cavity of bones.

4. Hemoglobin enables the erythrocyte to carry oxygen.

5. The life span of erythrocytes is 120 days.

6. Destruction of worn-out erythrocytes is called hemolysis.

7. The heme released iron and decomposes into a yellow pigment called bilirubin.

8. The three polymorphonuclear granulocytic leukocytes are Basophil,

Eosinophils, and Neutrophils

9. The two mononuclear agranulocytic leukocytes are Lymphocytes and

Monocytes.

10. Basophils contain dark-staining granules that stain with a basic dye.

11. Eosinophils contain granules that stain with eosin, a red acidic dye.

12. Neutrophils contain granules that are neutral.

13. Lymphocytes play an important role in the immune response that protects the

body against infection.

14. The four major plasma proteins are albumin, globulin, fibrinogen, and

prothrombin.

15. Edema results when too much fluid from blood leaks out into the tissues.

16. Alpha, Beta and Gamma are the three types of globulins.

17. The gamma globulins are immunoglobulin.

18. Immunoglobulins are separated from other plasma proteins by electrophoresis.

19. Plasmapheresis is the process of separating plasma from cells.

20. Human blood falls into four main types: A, B, AB and O.

21. Each of the blood types has a specific combination of factors called antigens and

antibodies.

22. People with O blood group are called universal donors.

23. The people with AB blood group are known as universal recipients.

24. Besides A and B antigen, the blood also contains another antigen called Rh

factor.

25. Heparin produced by the tissue cells is an example of anticoagulant.

26. Anemia is deficiency in erythrocytes or hemoglobin.

27. Failure of the blood cell production due to absence of development of bone

marrow cells is called Aplastic anemia.

28. General increase in RBC is called Polycythemia Vera.

29. Excessive bleeding caused by lack of one protein substances necessary for

clotting is called hemophilia.

30. Multiple pinpoint hemorrhages and accumulation of blood under the skin is called

Purpura.

31. Increase in cancerous WBC is called Leukemia.

32. Malignant neoplasm of bone marrow is called Multiple Myeloma.

33. Hematocrit is the test performed to know the percentage of erythrocytes in a

volume of blood.

34. Tonsils are masses of lymph tissue in throat near the oropharynx.

35. Adenoids are enlarged lymph tissue in the part of the throat near the nasal

passages.

36. Immunity can be broadly divided into Innate and Acquired.

37. Extreme hypersensitivity can cause Anaphylactic Shock.

38. Hodgkin’s lymphoma is a type of lymphoma in which antibody-producing cells

begin to grow abnormally.

39. A Person with type A blood has Aantigens and B antibodies in his or her blood.

40. Test for the presence of antibodies that coat and damage erythrocytes

antiglobulin Coombs test.
