What is the significance of RBC enumeration?
low rbcs count shows anaemia high rbcs count show polycythemia vera. rbcs enumerations shows the bonemarrow how much active.
Which form of hypoxia reflects poor O2 delivery resulting from too few RBCs or from RBCs that contain abnormal or too little hemoglobin?
Anemic Hypoxia
Does mature RBCs rely on anaerobic glycolysis?
Yes. Mature RBCs lack the necessary organelles to perform any other processes besides glycolysis. They rely on anaerobic glycolysis for energy.
How are red blood cells recycled?
Eventually the RBCs are unable to spring back into shape as they pass through capillaries and this lack of flexibility traps old RBCs in the spleen. The damaged RBCs are phagocytosed by macrophages, the proteins are hydrolyzed, iron is concentrated in transferrin and the chemical frame of the heme structure is partially disassembled and ultimately eliminated as part of the bile used in digestion. Millions of RBCs are born and recycled each day to maintain a constant level of oxygen in tissues .
What is the relationship between rapid rate of RBC destruction and jaundice?
The destruction of RBCs results in the release of bilirubin. If excessive amounts of RBCs are destroyed it creates a build up of bilirubin in the blood which leads to jaundice.
Why we can not extract DNA from RBCs?
We can not extract DNA from RBCs as they are without nucleus. only the source of DNA extraction is Leukocytes, RBCs are not good source of extraction but we can extract DNA from immature RBCs.
When counting RBCs and WBCs do you use a concentrated blood sample and a hemocytometer?
No, you will dilute the blood before putting it into the counting chamber (hemocytometer). RBC counts will typically be diluted with normal or isotonic saline, or a similar fluid. WBC counts will be diluted with a substance that will cause the lysis of non-nucleated RBCs (aka mature RBCs). The diluent used is usually 20% acetic acid, 1% HCl acid, Turk's acid (acetic acid and a stain), or 1% ammonium oxalate.

What test is used to determine the volume of packed RBCs?
Hematocrit measures the volumeof packed RBCs as a percentage of blood volume.
What is the percentage RBCs in your body?
45%
What is known as the graveyard of RBCs?
Appendix
What is the condition of too few RBCs or of RBCs with hemoglobin deficiencies?
Anaemia, kidney dysfunction, bleeding-excessive, vitamine B12 deficiency
What system is spleen lymphatic tissuue?
Yes, it is lympahtci tissue but is recycles RBCs and stores many RBCs in case of a massive blood loss.
Which form of hypoxia reflects poor O2 delivery resulting from too few RBCs or from RBCs that contain abnormal or too little hemoglobin?
Anemic Hypoxia
What is red blood cell mostly composed of?
rbcs. in hematocrit see the rbcs level settled down leaving plasma above.
