How is the movement of oxygen in body different from movement of carbon dioxide?

Oxygen is transported in the blood by binding to hemoglobin in red blood cells, while carbon dioxide is carried in the blood as bicarbonate ions dissolved in plasma. Oxygen is transported from the lungs to tissues for cellular respiration, while carbon dioxide is produced during cellular respiration and transported back to the lungs for exhalation. Oxygen is inhaled through the lungs, diffuses into the blood, and is delivered to tissues, whereas carbon dioxide is a waste product produced by cells and transported in the blood to the lungs for exhalation.
