ADVERTISEMENTS:
The upcoming discussion will update you about the differences between RBC and WBC.
Difference # RBC:
1. Physical Features:
RBCs are bi-concave disc shaped, and have no nucleus, size is roughly approximately 6-8 m.
ADVERTISEMENTS:
2. Life Span:
120 days.
3. Types:
There is only one type of RBCs found in the blood.
ADVERTISEMENTS:
4. Circulatory System:
Cardiovascular system.
5. Total Count RBC 700:1 WBC:
Males 4.6 million – 6.2 million per cubic mm females 4.2 million-5.4 million per cubic mm.
6. Functions:
Supplies oxygen to different parts of the body and carries carbon dioxide and other waste products.
7. Presence in Blood:
Makes up 36-50% of our blood depending on sex, height & weight.
8. Components:
ADVERTISEMENTS:
Hemoglobin.
9. Production:
Produced in red bone marrow.
10. Movement:
ADVERTISEMENTS:
They move in blood vessels eventually squeezing through capillaries giving O2 and nutrients to body cells.
11. Significance of Irregularity in Count:
A very low RBC count will result in anemia.
12. Nuclei:
ADVERTISEMENTS:
RBC do not have nuclei in humans.
13. Shape:
Biconcave disc.
Difference # WBC:
1. Physical Features:
ADVERTISEMENTS:
WBCs are irregular in shape, but have a nucleus and an outer buffer coat.
2. Life Span:
Few days but can live several days to years in healthy body.
3. Types:
There are various types of WBCs with distinct functions in the blood: neutrophils, T lymphocytes, B lymphocytes (plasma cell) monocytes (macrophage), eosinophils, basophils.
4. Circulatory System:
ADVERTISEMENTS:
Cardiovascular and lymphatic systems.
5. Total Count RBC 700:1 WBC:
4000 – 11000 per cubic mm.
6. Functions:
ADVERTISEMENTS:
Producing antibodies to develop immunity against infections. Some are phagocytic.
ADVERTISEMENTS:
7. Presence in Blood:
Close to 1% of the blood.
8. Components:
Antibodies with MHC antigen cell markers.
9. Production:
Produced in lymph nodes, spleen, etc.
10. Movement:
They leave the blood vessels and move to the injury site. Capable of diapedesis-squeeze between cells of blood vessel walls to exit circulation.
11. Significance of Irregularity in Count:
The WBC count goes up significantly when there is any infection present.
12. Nuclei:
WBC have nuclei in humans.
13. Shape:
Have different kinds of shapes and don’t change shape when multiplied.
