Chapter 10: The Respiratory System: Exchange of Gases • The respiratory system functions to __________ with the environment. • Air spaces in the skull called the __________ drain into the nasal cavity. • The lower pharynx serves as a passageway for both the __________ and __________ systems. • It is impossible to talk while swallowing because the __________ blocks the opening to the lower respiratory tract, routing food to the esophagus instead of the __________. • The structure nicknamed the "Adam's apple" is associated with the __________, part of the respiratory passageway. • Intrapulmonary __________ must be reduced prior to the process of inhalation. • Sound results from the __________ of the vocal cords as air passes through the larynx. • During the cough reflex, the trachea __________ slightly to increase the velocity of air movement • The anatomical design of the paired lungs makes them easy to distinguish; the right lung has __________ lobes, whereas the left side has __________ lobes. • The pleural cavity, which is located between the pleural membranes, contains small amounts of __________. • The exchange of gases in the lungs occurs between the alveoli and the __________. • The muscles involved in respiration include the __________ muscles located between the ribs and the __________ located between the thoracic cavity and the abdominal cavity. • The amount of air that enters and leaves the lungs with each breath is the __________. • The basic pattern of inhalation and exhalation is controlled by a region at the base of the brain called the __________. • Receptor cells in the aortic and carotid bodies respond to changes in blood __________ levels. • The concentration of __________ in the blood is monitored indirectly by monitoring the pH of the cerebrospinal fluid.
