Question

5. Eosinophils complexes. granular leukocytes that capture invading bacteria and antigen-antibody are 6. Monocytes, large white blood cells, have oval or horseshoe-shaped nuclei. 7. Serum is a clear, yellow liquid that causes blood to coagulate. 8. Fragments of cytoplasm that are smaller than either red or white blood cells are called pyrogens.. 9. Hemoglobin is released during hemolysis, the rupturing of red blood cells 10. Capillary puncture requires a superficial puncture of the skin with a sharp point. 11. A small, disposable instrument with a sharp point used to puncture the skin and make a shallow incision is known as a micropipette Chapter 48: Collecting, Processing, and Testinn Bland.

Answer 1

Ans) 5) True

Explaination:

Granulocytes include neutrophils, basophils,eosinophils, and mast cells. Their granules contain enzymes that damage or digest pathogens and release inflammatory mediators into the bloodstream. Mononuclear leukocytes include lymphocytes, monocytes, macrophages, and dendritic cells.

6) True

Explaination:

- Monocytes have generally lighter staining nuclei than do other leukocytes. The nucleus stains a pale bluish-violet, and the chromatin is fine.

- The nucleus may be round, kidney-bean shaped, folded, indented, or horseshoe, and may show "brain-like" convolutions.

7) True

Explaination:

It does not contain white or red blood cells or a clotting factor. It is the blood plasma without the fibrinogens. Serum includes all proteins not used in blood clotting (coagulation) and all the electrolytes, antibodies, antigens,hormones, and any extra substances (such as drugs and microorganisms)

8) False

Explaination:

- Pyrogens are polypeptide that produces fever by causing metabolic changes in the hypothalamus.

- Pyrogens are either exogenous (produced by infectious agents) or endogenous (produced by cells in the body such as macrophages).
