Dr. Shehrina Nazmin
,INTRODUCTION
• RBC means red blood corpuscle
• It is circular, non-nucleated, biconcave
disc containing hemoglobin
• Known as erythrocyte
• Number- 25 trillion in each human being
• Life span – 120 days
,NORMAL COUNT – AVERAGE (GY)
Adult male -
• 5.2 ± 0.3 million/cubic millimeter of blood
Adult female -
• 4.7 ± 0.3 million/cubic millimeter of blood
, MORPHOLOGY (GY)
Shape – circular, non-nucleated biconcave
disc
Diameter- 7.8 µm
Thickness – 2.5 µm at the thickest point and
1 µm at the center
Volume – 90-95 cubic micrometers
RBC contains approximately 34g hemoglobin
per 100ml of cells
