To help life, the body ought to make satisfactory energy. Energy is made by devouring molecules in food, which is done by the course of oxidation (by which food particles are gotten together with oxygen). Oxidation incorporates carbon and hydrogen being gotten together with oxygen to approach carbon dioxide and water. The use of oxygen and the making of carbon dioxide are consequently key to life. It follows that the human body ought to have an organ structure planned to shed carbon dioxide from the orbiting blood and hold oxygen from the air at a rate fast enough for the body's necessities, regardless, during top movement. The respiratory structure enables oxygen to enter the body and carbon dioxide to leave the body.The respiratory system starts at the nose and mouth and happen through the flying courses and the lungs. Air enters the respiratory system through the nose and mouth and passes down the throat (pharynx) and through the voice box, or larynx. The section to the larynx is covered by a little overlay of tissue (epiglottis) that thus closes during swallowing, consequently holding food or drink back from entering the flight courses.
