blood oxygenation

Blood oxygenation refers to the process of oxygen molecules attaching to red blood cells as they pass through the lungs. Hemoglobin, a protein in red blood cells, captures oxygen from inhaled air, allowing oxygen to be transported through the bloodstream to tissues and organs. This process is vital for cellular function and energy production. When blood is well oxygenated, tissues receive the oxygen they need to operate properly. Measuring blood oxygenation levels, often with a pulse oximeter, helps assess respiratory and circulatory health, ensuring the body's organs function optimally.
