The function of Hemoglobin

The correct answer is Transportation of oxygen.

Key Points

• Haemoglobin is a protein found in red blood cells.
• It is responsible for transporting oxygen from the lungs to tissues and organs throughout the body.
• Haemoglobin binds oxygen molecules in the lungs and releases them in tissues where oxygen is needed.
• The iron in Haemoglobin gives red blood cells their colour and is essential for oxygen binding.

Important Points

• Haemoglobin also plays a role in transporting carbon dioxide, a waste product, from tissues back to the lungs for exhalation.
• Proper levels of Haemoglobin are crucial for maintaining oxygen supply to the body and overall health.
