What is the primary function of hemoglobin?

• A. To regulate body temperature
• B. To produce immune responses
• C. To carry oxygen and carbon dioxide in the bloodstream
• D. To break down glucose

Answer: (C)

The primary function of hemoglobin in the body is to transport oxygen from the lungs to the tissues and facilitate the return of carbon dioxide from the tissues back to the lungs for exhalation. Hemoglobin is a protein found in red blood cells and is critically important for maintaining the body's oxygen levels, which are necessary for cellular respiration and energy production. By binding to oxygen when blood passes through the lungs and releasing it in tissues where it's needed, hemoglobin plays a vital role in sustaining life. Additionally, it helps in the transport of carbon dioxide, a metabolic waste product, back to the lungs, thus participating in the respiratory process. This function is essential for overall metabolic health and well-being.
