Red Blood Cells vs. White Blood Cells: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 21, 2023
Red blood cells transport oxygen; white blood cells fight infections.

Key Differences

Red blood cells, often abbreviated as RBCs, are primarily responsible for transporting oxygen from the lungs to the rest of the body. These cells contain a protein called hemoglobin, which binds to oxygen and gives blood its red color. White blood cells, on the other hand, serve as the body's primary defense mechanism against infections. These cells are essential components of the immune system and work diligently to detect and destroy pathogens.

In the bone marrow, both red blood cells and white blood cells are produced. While red blood cells are more numerous, making up about 40-45% of blood's volume, white blood cells are fewer but extremely vital. Different types of white blood cells are designed to combat various kinds of infections and diseases. Both types of cells have limited lifespans and need to be constantly replenished.

A drop in red blood cell count can result in conditions like anemia, which leads to fatigue, shortness of breath, and paleness. Conversely, an abnormal increase or decrease in white blood cell count can be indicative of infections, bone marrow diseases, or other immune system issues. Both red blood cells and white blood cells play crucial roles in maintaining homeostasis within the body.

Examining both red blood cells and white blood cells under a microscope reveals distinct differences. Red blood cells are typically biconcave discs without a nucleus, while white blood cells are larger, have a nucleus, and can change shape. Both cell types have unique movements, with red blood cells flowing smoothly in blood vessels and white blood cells exhibiting amoeboid movement to reach infection sites.
