Red Blood Cell Function: Oxygen Transport & Respiration

Respiration

The red blood cell's primary function is to transport oxygen from the lungs to the tissues and carbon dioxide from the tissues back to the lungs.

The red blood cells are involved in the process of respiration, which is the process of converting food into energy. Respiration occurs in the mitochondria of the cells, and it is where oxygen is used to break down glucose and produce carbon dioxide and energy-rich molecules.
