What is the main function of the red blood cells

To carry oxygen from the lungs to the body tissue to be used in cellular respiration.

Explanation:

When oxygen is brought to the cells, they perform cellular respiration, which changes toe oxygen into carbon dioxide and produces energy for the cells in the mitochondria.

The main job of red blood cells, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs. Hemoglobin (Hgb) is an important protein in the red blood cells that carries oxygen from the lungs to all parts of our body.
