Red Blood Cells vs White Blood Cells — Comparison Table
| Basis | Red Blood Cells | White Blood Cells |
|---|---|---|
| Main Function | Carry oxygen to tissues | Defend against infections |
| Nucleus | No nucleus (in mammals) | Contains nucleus |
| Lifespan | About 120 days | From few days to years |
| Number | Most abundant (4.5-5.5 million per microliter) | Less abundant (4000-11000 per microliter) |
| Color | Red due to hemoglobin | Colorless or white |
| Movement | Passive movement with blood flow | Can move independently (amoeboid) |
| Size | Smaller (7-8 micrometers) | Larger (10-20 micrometers) |
Key Points
- RBCs contain hemoglobin which binds oxygen; WBCs contain enzymes to fight bacteria
- RBCs lack nucleus so more space for oxygen; WBCs have nucleus for cell division
- RBCs are produced in bone marrow continuously; WBCs increase during infections
- RBCs have fixed shape (biconcave disc); WBCs have irregular shape and move freely
