Detailed explanation-1: -Hemoglobin is the oxygen-carrying protein that is found within all RBCs. It picks up oxygen where it is abundant (the lungs) and drops off oxygen where it is needed around the body. Hemoglobin is also the pigment that gives RBCs their red color.

Detailed explanation-2: -Hemoglobin is an oxygen-carrying protein found in red blood cells. It contains iron, and it gives the blood its red color. Q: What does hemoglobin do? Hemoglobin is vital to the body because it can bind to oxygen, carbon dioxide, and other groups such as sulfide and nitrogen oxide.

Detailed explanation-3: -Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body.

Detailed explanation-4: -Hemoglobin contains iron, which allows it to pick up oxygen from the air we breathe and deliver it everywhere in the body. You can think of hemoglobin as the iron ("heme"), oxygen transport protein, ("globin") found in red blood cells.

Detailed explanation-5: -As the red blood cells in blood travel through the lungs, oxygen molecules from the lungs attach to the hemoglobin, a protein in the blood cells that contains iron. The oxygen is then released to tissues and organs, and the hemoglobin bonds with carbon dioxide and other waste gases.
