RBC REVIEW STUDY PRACTICE TEST.
What is an erythrocyte? - CORRECT ANSWER A red blood cell
What is erythropiesis? - CORRECT ANSWER Making of RBC
Where does erythrosiesis take place? - CORRECT ANSWER Bone marrow
Order of precursor cells - CORRECT ANSWER MPSC, Rubriblast, prorubricyte, rubricyte, metarubricyte,
reticulocyte, erythrocyte
Why does a RBC have a limited life span? - CORRECT ANSWER No nucleus which means no cell
functions. (Membranes become less flexible and become destroyed by spleen)
Erythropoietic process - CORRECT ANSWER 1. Gradual Decrease in size
2. Decrease in basophillic cytoplasm (Gets lighter as it gets older)
3. Increase in density of the chromatin (nucleus gets darker)
4. Loss of nucleus
Write what you know about Diapedisis - CORRECT ANSWER Proestrogen bleeding occurs in response to
estrogen levels. First, high estrogen levels makes the dog go into proestrus, then the RBC squeeze thru
the pores of the capillary walls.
What does an erythrocyte do? - CORRECT ANSWER Carrier of O2 and CO2
Where is RBCs removed? - CORRECT ANSWER By the RES (reticulo-endothelial system)
What is the composition of hemoglobin - CORRECT ANSWER 4 heme molecules contain 1 iron atom
each
, Globin - two pairs of polypeptide chains
Porphyrin Ring
What are polypeptide chains made of? - CORRECT ANSWER Amino Acids
Compare a PCV to Machinery - CORRECT ANSWER PCV - Cheap, fast, pretty accurate, for small amount
of blood
Machinery - More accurate, reproducible, fast
What is plasma trapping? - CORRECT ANSWER When the centrifuge is spinning too slowly and traps the
plasma and other cells and falsely elevates the PCV
What does ESR stand for? - CORRECT ANSWER Erythrocyte Sedimentation Rate
What is ESR? - CORRECT ANSWER RBC settling by gravity
Is ESR used in Vet Medicine? - CORRECT ANSWER No, Because it is too time consuming
What happens to PCVs in young animals? - CORRECT ANSWER Young animals may have anemia due to
poor iron diets in nursing animals
What is normocytic? - CORRECT ANSWER Normal size
What is macrocytic? - CORRECT ANSWER Larger cell
What is microcytic ? - CORRECT ANSWER Smaller cell
What is polychromasia? - CORRECT ANSWER Multicolored - purple
What is normochromic? - CORRECT ANSWER normal color
What is an erythrocyte? - CORRECT ANSWER A red blood cell
