Detailed explanation-1: -In tiny blood vessels in the lung, the red blood cells pick up oxygen from inhaled (breathed in) air and carry it through the bloodstream to all parts of the body. When they reach their goal, they release it again. The cells need oxygen for metabolism, which creates carbon dioxide as a waste product.
Detailed explanation-2: -It carries oxygen. Red blood cells also remove carbon dioxide from your body, bringing it to the lungs for you to exhale.
Detailed explanation-3: -Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.
Detailed explanation-4: -Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body.
