into macrophages. What term best describes the shape of a red blood cell? What component of the formed elements has an important role in the formation of a blood clot? When you are doing a differential white blood cell count, the cell that you are least likely to identify is a True or False: If a person has type AB blood, it means that surface antigens A and B are not present on the cell membranes of red blood cells. True or False: If compatible blood types are mixed, agglutination will occur True or False: Universal precautions should always be used when carrying out laboratory activities that expose you to human body fluids- 5. 6. 7. 8. 9. 10.Explanation / Answer
The answer are as follows:
5. Biconcave ( the two sides of the RBC have a curvature inwards which giove it a biconcave shape)
6. Platelets and thrombocytes ( They take part in blood coagulation cascade)
7.Eosinophils and Basophils (This is due to the low concentration in blood ~1-2%)
8.. False (as on the surface of the RBC, both A and b antigens are present while the antibodies of A and B in the plasma are absent)
9. false (as agglutination occurs when uncompatible blood types are mixed dueto antigen antibody reaction)
10. True ( body fluids are catagorised a bio hazard substance and generally BS II and BS III are used for working with the body fluid samples)
