|
|
|
What are the agranulocytes?
|
Monocytes and Lymphocytes
|
|
|
Why do we need erythrocytes?
|
Because oxygen is poorly soluble in bodily fluids.
|
|
|
What are the components of blood?
|
Plasma, Erythrocytes, Thrombocytes, and Leukocytes
|
|
|
What percent of the blood cells is erythrocytes?

99%
|
|
|
What is the short form for hemoglobin?
|
Hb
|
|
|
What are leukocytes composed of?
|
3 classes of polymorphonuclear granulocytes and Agranulocytes.
|
|
|
what are the 3 classes of polymorphonuclear granulocytes?
|
Neutrophils, basophils, and Eosinophils.
|
|
|
What is the percent of Neutrophils in leukocytes?
|
50-70%
|
|
|
What may be the cause of an increase in the percentage of neutrophils?
|
Acute infection, as appendicitis, rheumatic fever, or smallpox.
|
|
|
What may be the cause of an decrease in the percentage of neutrophils?
|
Viral infection, as influenza, rubella, or hepatitis.
|
|
|
Why do neutrophiles have that name?
|
Because they're stained equally using basic or acid dyes.
|
|
|
Where are neutrophils generated?
|
bone marrow
|
|
|
How much time does making neutophils take?
|
6-8 days
|
|
|
How does neutrophils kill organisms?
|
1- NADPH releases reactive oxygen species.
2- Iton chelating proteins deprive microorganisms of iron which is essential for their proliferation. 3- A variety of antibacterial proteins and peptides are liberated from the granules and insert themselves into the microbial membrane. |
|
|
Why did basophils ger their name?
|
Because they stain with basic dyes.
|
|
|
What role does basophils play?
|
they play a role in inflammatory and immediate allrgic reactions.
|
|
|
Why do Eosinophils have that name?
|
Because they're readily stained with eosin.
|
|
|
Why is the constant motion of the blood important?
|
It keeps the cells well dispersed throughout the plasma.
|
|
|
What is the result os blood's slow motion?
|
a clot
|
|
|
How do we separate cells from plasma in a whole blood sample?
|
We add an anti-clotting agent to that sample and centrifuge
|
|
|
The ratio of the volume of red blood cells to the total volume as determined by separation of red blood cells from the plasma by centrifugation?
|
hematocrit
|
|
|
What is the hematocrit in men and women?
|
Men: 45%
Women: 42% |
|
|
A fraction of the centrifugated blood which contains most of the leukocytes
|
buffy coat
|
|
|
when is the buffy coat green?
|
when the sample contains a large number of neutrophils which are rich in green myeloperoxidase
|
|
|
Where are blood cells produced?
|
red bone marrow
|
|
|
Are all blood cells only produced by the read bone marrow?
|
No, Some white blood cells multiply in lymphoid tissue.
|
|
