oxygenated blood

Oxygenated blood is blood that carries a high concentration of oxygen from the lungs to the body's tissues. When you breathe in, your lungs absorb oxygen from the air and transfer it to the red blood cells. These cells then travel through the arteries, delivering oxygen to organs and muscles, which need it for energy and function. After releasing oxygen, the blood picks up carbon dioxide waste from the tissues, which is then transported back to the lungs to be exhaled. Essentially, oxygenated blood ensures your body's tissues receive the oxygen necessary for survival and performance.
