Detailed explanation-1: -Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body.

Detailed explanation-2: -Haemoglobin molecules inside red blood cells pick up and carry the oxygen. These oxygen-rich cells travel in the blood vessels from the lungs to the left side of the heart. The blood is then pumped around the body. Red blood cells are adapted for the transport of oxygen.

Detailed explanation-3: -Hemoglobin (Heme + Globin) The protein hemoglobin is a molecule which is responsible for carrying almost all of the oxygen in the blood. It is composed of four subunits, each with a heme group plus a globin chain. The heme group is composed of a porphyrin ring which contains an iron (Fe) atom in its center.

Detailed explanation-4: -Red blood cells contain a protein called haemoglobin, which carries oxygen from your lungs to all parts of your body. Haemoglobin is what makes your blood red. Red blood cells also help remove waste products from your body, such as carbon dioxide.

Detailed explanation-5: -Red blood cells pick up oxygen in the lungs. Blood travels away from the heart and lungs through the arteries (ar-tuh-reez). Red blood cells drop off oxygen to the cells through tiny tubes called capillaries (cap-ill-air-ies). Blood then returns to the heart through the veins (vayns) and the cycle begins again.
