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.

2. Life Span:

120 days.

3. Types:

There is only one type of RBCs found in the blood.

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:

Hemoglobin.

9. Production:

Produced in red bone marrow.

10. Movement:

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:

RBC do not have nuclei in humans.

13. Shape:

Biconcave disc.

Difference # WBC:

1. Physical Features:

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:

Cardiovascular and lymphatic systems.

5. Total Count RBC 700:1 WBC:

4000 – 11000 per cubic mm.

6. Functions:

Producing antibodies to develop immunity against infections. Some are phagocytic.

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.
