The word respiration describes several processes: Internal respiration is the exchange of respiratory gases between blood and the tissues. Cellular respiration is the process by which glucose or other small molecules are oxidised to produce energy: this requires oxygen and generates carbon dioxide. External respiration (breathing) involves simply the stage of taking oxygen from the air and returning carbon dioxide to it. Identify and give functions for each of the following: - larynx - To conduct air and, through the vocal cords, to produce sound. The entry of food and drink into the larynx is prevented by the structure of the larynx (epiglottis) and by the complicated act of swallowing. The larynx is protected by three pairs of folds which close off the airway. - trachea- The trachea (windpipe) extends from the neck into the thorax, where it divides into

[Below the larynx the trachea is usually open, and kept so by rings of cartilage in its walls. However it may be necessary to ensure that this condition is maintained by passing a tube (endotracheal intubation) to maintain the airway, especially post operatively if the patient has been given a muscle relaxant. Another common surgical procedure, tracheotomy, involves a small transverse cut in the neck. If this is done with anatomical knowledge no major structure is disturbed and the opening may be used for a suction tube, a ventilator, or in cases of tracheal obstruction as a permanent airway.]...
