| Size varies from 6 – 8 µm in diameter. | Size varies from 12 – 17 µm in diameter. |
| The lifespan of RBC is about 120 days. | The lifespan of WBC is around 12-20 days after which they are destroyed in the lymphatic system |
| Red blood cells do not have a nucleus on maturity. | WBCs are characterized by the presence of a large central nucleus. |
| Due to the presence of haemoglobin, these cells appear red in colour. | These cells are colourless, as they do not have any pigment. |
| Only one type of RBC exists. | Different types of WBCs are found in the blood such as neutrophils, B lymphocytes, T lymphocytes, monocytes, basophils, eosinophils. |
| They help in the transport of respiratory gases to different parts of the human body | They help in producing antibodies to fight against disease-causing microbes. |

| The components of red blood cells are haemoglobin. | The components of white blood cells are antibodies with the presence of MHC (major histocompatibility complex) antigen cell markers. |
| These cells make up around 36-50% of human blood. | They make up around 1% of the human blood. |
| RBC count: 5 million/ mm³ of blood. | WBC count: 7000–8000/mm³ of blood. |
| The process of formation of RBC is known as erythropoiesis. | The process of formation of WBC is known as leukopoiesis. |
| These cells move between the cardiovascular systems. | These cells move between the cardiovascular and lymphatic systems. |
| Low count of RBCs results in Anaemia. | Low count of WBCs results in Leukopenia. |
