Cards

Term
erythropoiesis
Definition
Means RBC production and it occurs in the bone marrow
Term

Fe++.

Vitamin B12

folic acid

amino acids

lipids 

Definition
What five things does Erythopoiesis require?
Term
builds RBC
Definition
what does folic acid do?
Term
negative
Definition
Erythropoeisis is what kind of feedback?
Term

Stimulus: hypoxia

 

Kidney secretes the hormone erythropoietin

 

Erythropoietin increases the rate of RBC production 

 

more red cells cause increased oxygen to deliver to the kidney

 

the rate of RBC production slows 

Definition
five steps to erythropoiesis
Term
when less oxygen is delivered to the kidney a stimulus goes to the marrow and tells it to make more RBCs at a faster pace
Definition
what is hypoxia
Term
proerythroblast
Definition
what cell stimulates the stem cell?
Term
reticulocyte
Definition
what is the final stage prior to mature RBC
Term
not having enough hemoglobin
Definition
what is anemia?
Term
polycythemia
Definition
what is the overproducation of RBC and other cells?
Term

either a lower RBC count with a normal amount of hemoglobin in each cell

 

or a normal RBC number but now enough hemoglobin in the cells 

Definition
what two things cause anemia?
Term

higher viscosity of blood causes slow flow

 

predisposes to clotting 

Definition
which two things cause polycthemia
Term
leukocytes
Definition
what are white blood cells called?
Term
granular and agranular
Definition
what are the two different types of leukocytes (WBC)
Term

lymphocytes 25%

monocytes  6%

Definition

what two types of leukocytes are agranular?

What are their percentages? 

Term

basophils 1%

neutrophils 65%

eosinophils 3% 

Definition
what three leukocytes are granular?
Term
granulocytes and monocytes
Definition
what two white blood cells are produced in myeloid tissue?
Term
lymphocytes
Definition
what white blood cell is produced in the lymphatic tissue like the spleen, nodes and tonsils?
Term
absolute white blood cell count
Definition
means that the total number of white cells is elevated
Term
Differential WBC count
Definition
means certain types of white cells elevated
Term
bacterial
Definition
when neutrophil counts are elevated what infection is occuring?
Term
alleregy or parasites
Definition
an elevated amount of eosinophils means that what is wrong?
Term
viral
Definition
an elevated amount amount of lymphocytes means you have what kind of infection?
