5 True/False questions
ABO Blood Groups: Type A → Type A
Antigen A on RBC
Anti-B antibody in serum
Antigens (agglutinogens) → 1. Protein that reacts against a specific antigen
2. in the plasma
3. goes after foreign blood types. For example, if you are type A & you get type B, antibody will go after type B
Note: antibodies is what on test, not agglutinins
Red Blood Cells (Erythrocytes) → Protect body against microorganisms and remove dead cells and debris, infection. Can level the blood vessels. work like an ameoba.
Plasma: Waste Products → Proteins:
1. Albumins: viscosity, osmotic pressure, buffer, transports fatty acids, free bilirubin, thyroid hormones
2. Globulins: transports lipids, carbohydrates, hormones, ions, antibodies, and complement
3. Fibrinogen: blood clotting
4. Most plasma proteins synthesized by liver
5. Gamma globulins synthesized by plasma cells (B cells)
Complete Blood Count (CBC) → 1. Hematocrit
2. Hemoglobin concentration
3. Total count for RBCs, reticulocytes, WBCs, and platelets
4. Differential WBC count
5. RBC size and hemoglobin concentration per RBC
