1. Blood

2. Blood is:
55% Plasma
45% Cells
What is plasma?

3. Plasma is the
liquid portion
of blood

4. 91.5% water. Transport medium.
Plasma is:
91.5% water. Transport medium.
7% proteins, e.g., clotting factors, antibodies
1.5% other solutes, e.g., hormones,vitamins, amino
acids, glucose, fatty acids, nitrogen wastes,
electrolytes (Ca++, Na+, K+, H+)

5. What kinds of
cells do we find
in the blood?

6. Red Blood Cells (RBCs) = Erythrocytes
>99% of total blood cells are RBCs
~5 million/ml Hb Fe
Transport O2 and CO2
No nucleus when mature

7. Platelets = Thrombocytes
Involved in blood clotting
150,000 – 400,000/ml

8. White Blood Cells (WBCs) = Leukocytes
Defense system
5,000 – 10,000/ml
There are 5 different types of WBCs

9. Neutrophils = PMNs = Polymorphonucleocytes
or Poly’s
Most abundant of
the WBCs
Phagocytic
Kill bacteria

10. Basophils Release histamine. Their numbers increase
in allergic reactions

11. Eosinophils Fight parasitic infections Some allergic reactions,
esp. asthma, are the
result of the malfunction-
ing of eosinophils.

12. Lymphocytes
Produce antibodies
Fight viruses

13. What % of blood is plasma?

D.) 90
E.)

14. Monocytes Size-wise, is largest of the WBCs Phagocytic
Large kidney-shaped
nucleus

15. The blood cell that releases histamine in an allergic reaction is
iRespond Question F

16. Important Hematology Lab Terms
1. CBC = Complete Blood Count
Normal (nl) values:
RBCs: million/ml
WBCs: 5,000-10,000/ml
Platelets: 100,000 – 400,000/ml

17. CBC c diff (differential)
Nl values:
PMNs: 60-70%
Lymphos: 20-25%
Monos: 3-8%
Eos: 2-4%
Basos: 0.5-1%

18. Hematocrit (or ‘crit, if you want to sound cool)
The percent of whole blood made up of red
blood cells.
Nl value: 40-50%
Let’s run a virtual
hematocrit

19. Hemoglobin – Hb Do you remember what hemoglobin is?
A nl hemoglobin value is 12-16g/dl
