Oxygen is inhaled into the lungs where it is delivered to red blood cells and carried through the bloodstream to all tissues and cells in the body. Inside the cells, oxygen is used in a process called cellular respiration to produce energy in the form of ATP, which is essential for various physiological functions and activities. Carbon dioxide, a waste product of this process, is then carried back to the lungs to be exhaled from the body.
