Hemoglobin gives RBC's the ability to?

Hemoglobin gives red blood cells (RBCs) the ability to transport oxygen from the lungs to tissues throughout the body and to carry carbon dioxide from the tissues back to the lungs for exhalation. This protein binds oxygen molecules efficiently due to its iron content, allowing for effective gas exchange. Additionally, hemoglobin plays a crucial role in maintaining the acid-base balance in the blood.
