RED BLOOD CORPUSCLES (ERYTHROCYTES)
Red blood cell is a circular binconcave disc shaped non nucleated cell (and hence corpuscles) it contains respiratory pigment haemoglobin normal RBC on an average is 7.2u in diameter and 2.2u in thickness it is thinner in the centre with a thickness of 1.7u under the microscope it looks transluscent in the centre and dumbell shaped when viewed from side
Normal Count :
The normal RBC count is 5.000.000(5 millions)/cmm in adult male and 4500000 (4.5 millions)/cmm in adult female in infants it is 6-7 millions /cmm and in foretus it is 8 millions/cmm
composition:
red blood corpuscles is composed of 60-70% water with and 30-40% of solids which are formed mostly of ;(1) haemoglobin which is (a conjugated protein having the protein globin conjugated with iron containing haem) (2) stroma proteins (3) phospholipids (4) organic and (5) inorganic substances
To sum up RBC"s chief protein is globin metal is iron lipid is globin metal is iron lipid is phospholipid and salt is potassium phosphate
