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.

Detailed explanation-3: -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. It’s the hemoglobin that gives red blood cells their color, too.

Detailed explanation-4: -RBCs contain hemoglobin (pronounced: HEE-muh-glow-bin), a protein that carries oxygen. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs.

Detailed explanation-5: -Red blood cells contain hemoglobin and are covered with a membrane composed of proteins and lipids. Hemoglobin-an iron-rich protein that gives blood its red color-enables red blood cells to transport oxygen and carbon dioxide.
