Gce Model Questions Vol1 2024 Biology Question 10
Practice objective / multiple choice question 10 from the 2024 Gce Model Questions Vol1 Biology examination.
Refer to the labelled diagram of the human respiratory system. During quiet inhalation the diaphragm contracts, moving downwards and increasing the thoracic cavity volume by 0.5 L, while the rib cage expands, adding a further 0.3 L. Assuming the initial lung volume at the end of a normal exhalation is 2.5 L and atmospheric pressure is 760 mm Hg, use Boyle's law to calculate the average intrathoracic pressure at the midpoint of the inhalation (i.e., when the total volume increase is half of 0.8 L). Give your answer in mm Hg to the nearest whole number.
