Oxygen delivery refers to the process by which oxygen is transported from the lungs to the body's tissues. This occurs primarily through the bloodstream, where oxygen binds to hemoglobin in red blood cells. Once in the tissues, oxygen is released to support cellular functions and energy production. Effective oxygen delivery is crucial for maintaining overall health. Factors such as respiratory rate, heart function, and blood circulation can influence how well oxygen is delivered. Conditions like asthma or anemia can impair this process, leading to insufficient oxygen reaching the body's cells.
