Verified step by step guidance

Understand the role of hemoglobin: Hemoglobin is a protein found in red blood cells that is primarily responsible for transporting gases in the blood.

Identify the main gases involved in respiratory transport: The primary gases transported by hemoglobin are oxygen (O₂) and carbon dioxide (CO₂).

Focus on oxygen transport: Hemoglobin binds to oxygen in the lungs, where oxygen concentration is high, forming oxyhemoglobin.

Consider the transport process: As blood circulates to tissues, hemoglobin releases oxygen where it is needed, facilitating cellular respiration.

Recognize the primary function: While hemoglobin can also transport carbon dioxide, its main function is to carry oxygen from the lungs to the body's tissues.
