What is the main function of red blood cells?

To fight infections
To transport oxygen
To produce clots
To regulate body temperature

The correct answer is: To transport oxygen

The main function of red blood cells is to transport oxygen throughout the body. These specialized cells contain hemoglobin, a protein that binds to oxygen in the lungs and carries it to various tissues and organs. This oxygen transport is crucial for cellular respiration, allowing cells to produce energy effectively. While other components of the blood play roles in fighting infections, producing blood clots, and regulating body temperature, red blood cells are primarily dedicated to ensuring that the body's cells receive the oxygen they need to function optimally. This focus on oxygen transport underscores the unique and vital role red blood cells play in maintaining overall health and supporting metabolic processes.
