A contraction of the smooth muscle in the walls of the bronchi and bronchioles that tighten and squeeze the airway shut is known as a/an ______________
Oxygen in air must diffuse across______ to enter the blood. a. pleural sacs b. alveolar sacs c. a moist respiratory surface d. both b and c
During inhalation, ________. a. the thoracic cavity expands d. the diaphragm relaxes c. atmospheric pressure declines d. the lungs deflate
Gas exchange occurs at the _______. a. two bronchi b. pleural sacs c. alveoli d. both b and c
How would paralysis of the diaphragm alter inspiration? It would prevent contraction of the intercostal muscles It would prevent inhalation because the intrapleural pressure would not change It would decrease the intrapleural pressure and allow more air to enter the lungs It would slow expiration because the lung would not relax.
