Oxygen first is inhaled through the nasal cavity and then passes through the trachea, through the bronchi and into the lungs.

The heart pumps this oxygenated blood throughout the body, primarily to organs and muscle cells, where it is consumed in respiration and is converted to carbon dioxide and excreted.
