Exercise 26 – Blood Components and Blood Tests
Reviewing Your Knowledge
A. Characteristics of the Formed Elements and Blood Abnormalities
1.
red blood cells
2.
white blood cells
3.
platelets
4.
erythrocytes
5.
thrombocytes
6.
leukocytes
7.
megakaryocytes
8.
anemia
9.
polycythemia
10. leukocytosis
11. leukopenia
12. thrombocytopenia
B. White Blood Cell Structure and Characteristics
1.
neutrophils
2.
eosinophils
3.
basophils
4.
lymphocytes
5.
monocytes
6.
neutrophils
7.
eosinophils
8.
basophils
9.
lymphocytes
10. monocytes
11. PMNs
12. leukocytes
13-14.segs, polymorphonuclear leukocytes (PMN)
C. White Blood Cells
1-3. neutrophils, eosinophils, basophils
4-5. lymphocytes, monocytes
6.
neutrophils
7.
basophils
D. ABO and Rh Blood Typing
1. Antigens: Rh; Antibodies: anti-A, anti-B
2. Antigens: A; Antibodies: anti-B (also has anti-Rh antibodies if exposed to Rh+ blood)
3. Antigens: B; Antibodies: anti-A (also has anti-Rh antibodies if exposed to Rh+ blood)
4. Antigens: A,B,Rh; Antibodies: none
5. The universal blood donor is O-. This blood type has no antigens for antibodies from A, B, or
AB blood groups to attack.
6. The universal recipient is AB+ because this blood type has no antibodies to attack any other
blood group.
E. Hematocrit
1.
The percent of RBCs in whole blood
2.
heparin
3.
yes (40-50%)
4.
no; it's high (38-46%)
F. Hemoglobin Content and Coagulation Time
2
1. No. The hematocrit measures the percent of RBCs in whole blood and the hemoglobin content
determines the oxygen-carrying ability of the blood and is described in mg/ml of blood.
2. Coagulation time measures how long it takes for the blood to clot.
3. A person with hemophelia will have a longer than normal coagulation time.
