Hallet C.E., Austin L., Caress A., Luker K.A. The bronchi and bronchioles also use the mucus and cilia of their epithelial lining to trap and move dust and other contaminants away from the lungs. Notice whether the larynx stays in the same place when you say "ah.". To exhale air, the diaphragm and external intercostal muscles relax while the internal intercostal muscles contract to reduce the volume of the thorax and increase the pressure within the thoracic cavity.

E) thalamus and corpus callosum, Hyperventilation leads to all of the following except: It is situated just below where the tract of the pharynx splits into the trachea and the esophagus. Air entering the lungs from the atmosphere has a higher partial pressure of oxygen and a lower partial pressure of carbon dioxide than does the blood in the capillaries. The epiglottis is also attached to the hyoid bone by the hyoepiglottic ligament which extends from the anterosuperior surface of the epiglottis to the body of the hyoid bone. The pharynx is opened or closed by two mechanisms: (1) Contractions of the cricothyroid and of the intrinsic muscles of the larynx open and close the vocal cords.
