A comparative study between red blood cells,white blood cells and platelets are given below:
RED
BLOOD CELLS{R.B.C}
|
WHITE
BLOOD CELLS{W.B.C}
|
PLATELETS
|
1)It is also known as red blood
corpuscles,red blood cells or erythrocytes.
|
1)It is also known as white blood
corpuscles,white blood cells or leukocytes.
|
1)It is also known as platelets or
thrombocytes.
|
2)It’s viability is 120 days.
|
2)It’s viability is 20 days.
|
2)It’s viability is 5-10 days.
|
3)The number of R.B.C is 5 million per
cubic milliliter in male.Comparatively less in female.
|
3)The number of W.B.C is 5-10 thousand
in a human body.
|
3)2.5 million of platelets is present
in a human body.
|
4)Here nucleus is absent.
|
4)Here nucleus is present.
|
4)Here nucleus is absent.
|
5)It looks red due to the presence of
haemoglobin pigment.
|
5)It looks red.
|
5)Not mentioned.
|
6)It is bi-concave,circular and disc
shaped.
|
6)It is irregular in shape.
|
6)It is spindle like structure.
|
7)It transports CO2 and O2.
|
7)It acts as a guard,destroys the
germs and produces antibodies.
|
7)It helps in coagulation of blood.
|
8)It is produced in bone marrow.
|
8)It is produced in red bone marrow
and ductless glands.
|
8)It is produced in bone marrow.
|
9)Number of R.B.C is 500 times more
than number of W.B.C.
|
9)Number of W.B.C is the lowest.
|
9)Number of platelets is comparatively
more than W.B.C but less than R.B.C.
|
10)Deficiency of R.B.C causes anemia.
|
10)Deficiency of W.B.C causes
leukemia.
|
10)Deficiency of platelets causes
delay in blood coagulation.
|

substance.
|
11)It doesn’t secret any chemical
substance.
