Verified step by step guidance

Red blood cells, also known as erythrocytes, are primarily responsible for transporting gases within the body.

The main function of red blood cells is to carry oxygen from the lungs to the tissues throughout the body. This is facilitated by the protein hemoglobin, which binds oxygen molecules.

Once oxygen is delivered to the tissues, red blood cells then collect carbon dioxide, a waste product of cellular metabolism, and transport it back to the lungs for exhalation.

This gas exchange process is crucial for maintaining cellular respiration and energy production in body tissues.

While red blood cells are involved in gas transport, other functions like antibody production, blood clotting, and temperature regulation are performed by different components of the blood or body systems.
