Choose the item in column 2 that best matches each item in column 1. Match the following: 11) No exchange of gases occurs here. 12) Secrete a fluid containing surfactant. 13) Where the respiratory zone of the lungs begins. 14) Composed of simple squamous epithelium.

16) Composed of cuboidal cells. 17) The respiratory membrane is composed of fused basement membrane of the capillary walls and ________. A) Type I cells B) Alveolar duct C) Type II cells 15) 16) 17) TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false. 18) Ventilation perfusion coupling means that more blood flows past functional alveoli than past nonfunctional alveoli. 18) 19) The olfactory mucosal lining of the nasal cavity contains the receptors for the sense of smell. 19) 20) The functions of the nasal conchae are to enhance the air turbulence in the cavity and to increase the mucosal surface area exposed to the air. 20) 21) The lungs are perfused by two circulations: the pulmonary and the bronchial. The pulmonary circulation is for oxygenation of blood. The bronchial circulation supplies blood to the lung structures (tissue). 21) 22) Changes in arterial pH can modify respiration rate and rhythm even when carbon dioxide and oxygen levels are normal. 22) 23) Intrapleural pressure is normally about 4 mm Hg less than the pressure in the alveoli. 23) 24) During normal quiet breathing, approximately 750 ml of air moves into and out of the lungs with each breath. 24) 25) The alveolar ventilation rate is the best index of effective ventilation. 25) 26) In chronic bronchitis, mucus production is decreased and this leads to the inflammation and fibrosis of the mucosal lining of the bronchial tree. 26) 27) Labored breathing is termed dyspnea. 27) 28) The largest amount of carbon dioxide is transported in the bloodstream in the form of carbonic anhydrase. 28) 29) Increased temperature results in decreased O 2 unloading from hemoglobin. 29) 30) The epiglottis is a smooth muscle that covers the glottis during swallowing. 30) 31) Valsalva's maneuver involves closing off the glottis (preventing expiration) while contracting the muscles of expiration, causing an increase in intra - abdominal pressure. 31)
