Short Answer
Red blood cells carry oxygen from the lungs to all parts of the body and return carbon dioxide to the lungs to be exhaled.
Detailed Explanation
Red blood cells (RBCs) contain a protein called haemoglobin, which binds with oxygen.
Their main functions include:
- Transporting oxygen throughout the body.
- Carrying carbon dioxide back to the lungs.
- Supporting healthy organ function.
- Helping muscles and tissues produce energy.
Patients with severe blood loss, anemia, surgery, or trauma often require red blood cell transfusions.
