Rbc¶
## Size 6-8um
Nucleus¶
- Anuclear
Reason for biconcave¶
- white middle due to no hemoglobulin protein
- Flexible to passing in capillaries
- increased surface area for o2 binding ## Color --> Red - Eosin binding to protein
Lifespan¶
- 100 -120Days
Erythropoiesis¶
- Basophilic = Blue color (Nucleus)
- Eosinophilia = Red color (protein)
| Regions | Pro-Erythroblast | Basophilic Erythroblast | PolyChromatic Erythroblast | Normoblast | Reticulocyte | Erythrocyte |
|---|---|---|---|---|---|---|
| Nucleus | 1-2 nucleoli for Ribosomal syntheisi | Nucleoli not seen = ribosomes produced | Small,heterochromatin = all mRNA Synthesised | Pyknotic | Nucleus removed | No nucleus |
| Cytoplasm | Light blue -no work so thin | Basophilic =Ribosomes presence | Eosinophilic = Proteins produced by ribosomes | Pink and light purple = proteins,ribisomes | Light purple to pink = proteins,ribosomes still there | Pink = only proteins Concave Shaped |
| Function | comes out of marrow ,if very Hematocrit |
