difference between red blood cells and white blood cells and write their functions

Answer 1

Difference Between RBC and WBC

Red Blood cells or Erythrocytes (RBC) constitute major part of the formed elements. They are non nucleated tiny biconcave disc in mammals except camel and llama (oval shaped ).
The function of RBC is to carry oxygen from the lungs to the tissues and CO2 from the tissues to the lungs. This is due to the presence of haemoglobin. RBC also participates in the transport of carbon dioxide as bicarbonates.

White Blood Cells (WBC) or Corpuscles are also known as leucocytes. Their number is much less than RBC (the ratio of WBC and RBC 1: 600). WBC provides defence mechanism to the body against infection.
Based on the presence or absence of cytoplasmic granules, WBC are classified as granulocytes (Neutrophils, eosinophils and basophils) and agranulocytes (Lymphocytes and Monocytes) .

Answer 2

Red Blood Cells or RBC and White Blood cells are two of three cellular portions of blood.

♡ The RBC carry oxygen from the lungs to tissues or it is responsible for transport of respiratory gases ( O2 and CO2 ).

☆ They posses haemoglobin and so they are red.

☆ Life span : 120 days

♡ Their nucleus is not at maturity.

☆Formation process is called aserythropoises.

WBC provides defence power to body against infection. When a virus or bacteria enters into our body, WBC resists it and make us immune.

☆ Their nucleus is large and characterized.

♡ They havw no pigment and so they are colourless .

☆ Life span : Few months to years , according to the body needs.

♡ It is formed at red bone marrow.
Formation process is called leucopoeises.
