The nasopharynx is the superior region of the pharynx found in the posterior of the nasal cavity. G) epiglottis The information we provide is grounded on academic literature and peer-reviewed research. b. pharynx d. trachea Each mucous membrane-covered vocal fold contains a vocal ligament that extends from the inner surface of the thyroid cartilage to the vocal process of the corresponding arytenoid cartilage. pg. (Assume that her running direction is the positive direction.) Air inhaled through the oral cavity enters the pharynx at the oropharynx. (c) NaNO3\mathrm{NaNO}_3NaNO3 H) main (primary) bronchus 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. Glottis is medical terminology for the opening of larynx into the airway. 448, Even after a forceful expiration, air still remains in the lungs for gas exchange to continue. a. atelectasis The opening of the larynx is called the glottis. A. epiglottis B. glottis C. trachea D. thyroid cartilage A. epiglottis Which part of the larynx produces sounds when air passes by? a . She slides for 1.1 s, just reaching the plate as she stops (safe, of course). E) residual volume When the diaphragm contracts, it moves inferiorly a few inches into the abdominal cavity, expanding the space within the thoracic cavity and pulling air into the lungs. A) resorbin pg. The large shield-shaped thryoid cartilage that protrudes anteriorly is commonly called the ____. Moore, K., Dalley, A. The cricoid cartilage is a much smaller signet ring-shaped hyaline cartilage located directly below the thyroid cartilage. However, newborns and infants can do this while swallowing milk. C) expiratory reserve volume The larynx is drained by corresponding veins, namely the superior and inferior laryngeal veins. a. true The pharynx is divided into 3 regions: the nasopharynx, oropharynx, and laryngopharynx. d. hiccup pg. The difference in partial pressures causes the gases to diffuse passively along their pressure gradients from high to low pressure through the simple squamous epithelium lining of the alveoli. pg. E) residual volume New York: McGraw-Hill. pg. 445, Inspiration results when the diaphragm and external intercostal muscles relax. 445, Expiration occurs when the thoracic and intrapulmonary volumes decrease and the intrapulmonary pressure increases. pg. The negative pressure system of the respiratory system involves the establishment of a negative pressure gradient between the alveoli and the external atmosphere. The epiglottis, which is located just superior to the larynx is a flap-like structure that covers the opening of the larynx during swallowing. a. cellular respiration It is attached by its stalk to the inner aspect of the angle formed by the laminae of the thyroid cartilage via the thyroepiglottic ligament in the midline. A) bronchioles The last unpaired cartilage, the epiglottis, is a large leaf-shaped elastic cartilage that is covered by mucous membrane. pg. d. mucus b. it slows the down the movement of cilia 445-447, b. relaxation of the external intercostal muscles helps increase the size of the thoracic cavity, The presence of air in the intrapleural space is known as ________. A) vital capacity a. pleurisy D) inspiratory reserve volume a. contraction of the diaphragm muscle helps increase the size of the thoracic cavity b. nose, larynx, pharynx, trachea, main (primary) bronchi pg. B) SIDS b. air is not moistened, warmed, or filtered before reaching the lungs pg. a. true 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. D) the right lung has three lobes protects the superior opening of the larynx. c. methane e. buildup of carbon dioxide in the blood b. Solved What are functions of the larynx?
