Cells that have granules in their cytoplasm
Cells that have no granules in their cytoplasm
What are the granulocytes?
Neutrophils, Basophils, and Eosinophils
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?
What is the short form for hemoglobin?
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?
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?
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.
What is the lifespan of an erythrocyte?
~120 days
What hormone regulates the production of erythrocytes?, and where is it produced?
Erythropoietin(EPO), which is made in the kidneys.
What is a band cell?
an immature neutrophil
What does a great number of band cells indicate?
an active infection
What's another name for blood clotting?
