antigen and antibody reaction. Materials Gloves, alcohol wipes, Band-Aids, toothpicks Lancet Microscope slides Anti-Serum Microscopes Pre-Lab Evaluation Questions The pre-lab evaluation questions must be answered prior to lab and demonstrated to your lab instructor. You must read through the assigned chapter readings, lab introduction, objectives, overview and procedure to answer these questions. Please cite your work for any reference source you utilize in answering these questions. 1. Define the components of blood and briefly describe their role. Erythrocyte, RBC- Transport O2 to tissues throughout the body and remove CO2 from the body Leukocyte, WBC- Defend against infections Thrombocytes, Platelets- Assist in hemostasis and prevent infection. Plasma- assisting in maintaining homeostasis by transporting proteins and other nutrients to throughout the body (Betts, 2017). 2. Describe the morphology of an erythrocyte and the importance of it. What role does hemoglobin have within the erythrocyte function? Why is iron so important within erythrocyte function? RBCs are biconcave shape that are a relatively flat disc with no nucleus or organelles. They also contain millions of hemoglobin which contains iron to facilitate the transport of O2 and CO2 throughout the body. Iron is found in the heme group of molecules actually reversibly binds the O2 and CO2 molecules to the cell (Betts, 2017).

3. Compare and contrast the various types of leukocytes. granulocytes: Neutrophils- r/t bacterial infections and inflammation, respond to almost any infection. Basophils- Rarest WBC, release histamines which are involved in the inflammatory process. Eosinophils- Active against parasites in the body, such as worms (Betts, 2017). Agranulocytes: Lymphocytes- found in lymph tissue, consist of T and B lymphocytes with specific immunities. Monocytes- The largest WBCs, macrophages are phagocytic cells that clean up dead or damaged human cells, as well as bacteria, viruses, and other cellular debris (Betts, 2017). 4. What is a complete blood count (CBC) and the importance of its clinical use? Compare and contrast the MCV, MCH, MCHC, and RDW tests of the CBC. The CBC measures several components and features of your blood including: RBCs, WBCs, Hgb, Hct, and platelets. This is a non-definitive test that can help determine the overall health of an individual. MCV- Measures the average size of a single RBC MCH- is an average of the amount of Hgb inside a single RBC MCHC- is an average of the concentration of Hgb in a single RBC RDW- Measures the range in size of RBCs in a blood sample (Betts, 2017). 5. What is the difference between the ABO blood group and the Rh blood group? How are these blood groups determined on an individual and utilized in the health care profession? ABO blood typing is dependent on the antigens found on the surface of the blood. This determines which blood will not be considered an “invader” by the body and attacked as such.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
