| Video Discription | Learn more about the respiratory system: https://www.merckmanuals.com/home/lung-and-airway-disorders/biology-of-the-lungs-and-airways/respiratory-system To sustain life, the body must produce sufficient energy. Energy is produced by burning molecules in food, which is done by the process of oxidation (whereby food molecules are combined with oxygen). Oxidation involves carbon and hydrogen being combined with oxygen to form carbon dioxide and water. The consumption of oxygen and the production of carbon dioxide are thus indispensable to life. It follows that the human body must have an organ system designed to eliminate carbon dioxide from the circulating blood and absorb oxygen from the atmosphere at a rate rapid enough for the body’s needs, even during peak exercise. The respiratory system enables oxygen to enter the body and carbon dioxide to leave the body. The respiratory system starts at the nose and mouth and continues through the airways 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 entrance to the larynx is covered by a small flap of tissue, the epiglottis, that automatically closes during swallowing, thus preventing food or drink from entering the airways. #respiratoryphysiology #respiratorysystem #lungs #breathing About Merck Manuals: Access to MerckManuals.com, an online medical reference, is unlimited and always free.
