Finally, the millions of tiny terminal bronchioles conduct air to the alveoli of the lungs. They also tightly close during swallowing. E) plasma, The bluish cast that results from inadequate oxygenation of the skin and mucosa is called: a. pulmonary ventilation When the partial pressure of carbon dioxide is low in the lungs, the reactions reverse and carbon dioxide is liberated into the lungs to be exhaled. Anatomy of the larynx and trachea | Osmosis C) melanosis The opening of larynx into pharynx known as the laryngeal inlet is about 4-5 centimeters in diameter. It plays a vital role in the respiratory tract by allowing air to pass through it while keeping food and drink from blocking the airway. Philadelphia: Wolters Kluwer Health/Lippincott Williams & Wilkins. It branches off from the vagus nerve and then divides into two major branches, one sensory (detects sensations) and one motor (involved in movement).
