Detailed explanation-1: -What Is the Function of Red Blood Cells? Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.
Detailed explanation-2: -Red blood cells squeeze through narrow capillaries in single file. 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.
Detailed explanation-3: -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-4: -A type of blood cell that is made in the bone marrow and found in the blood. Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body.
Detailed explanation-5: -Red blood cells, also known as erythrocytes, deliver oxygen to the tissues in your body. Oxygen turns into energy and your tissues release carbon dioxide. Your red blood cells also transport carbon dioxide to your lungs for you to exhale.
