What is the high concentration in deoxygenated blood?

Deoxygenated blood has a high concentration of carbon dioxide (CO2) and metabolic waste products, as it carries carbon dioxide from the body's tissues back to the lungs for exhalation. It also contains lower levels of oxygen (O2) compared to oxygenated blood. This composition is critical for maintaining the body's acid-base balance and facilitating the removal of waste products.
