No, white blood cells (WBCs), also known as leukocytes, do not carry oxygen.
While red blood cells (RBCs) are responsible for oxygen transport via hemoglobin, white blood cells are a crucial part of the immune system, defending the body against infection and disease. Their primary function is to identify and neutralize pathogens, produce antibodies, and remove damaged or dead cells.
| Blood Cell Type | Primary Function | Oxygen Transport |
|---|---|---|
| Red Blood Cells | Oxygen transport | Yes |
| White Blood Cells | Immune system defense | No |
| Platelets | Blood clotting | No |
In summary, the task of carrying oxygen is handled by red blood cells, not white blood cells. White blood cells are dedicated to immune defense.
