Detailed explanation-1: -All red blood cells contain a red pigment known as hemoglobin. Oxygen binds to hemoglobin, and is transported around the body in that way. 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.
Detailed explanation-2: -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.
Detailed explanation-3: -It carries oxygen. Red blood cells also remove carbon dioxide from your body, bringing it to the lungs for you to exhale. Red blood cells are made in the bone marrow.
Detailed explanation-4: -The main job of red blood cells, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs.
