1. A(n)__________ (increase/decrease) in thoracic volume leads to an increase in intrapulmonary pressure.

Solution

.A decrease in thoracic volume leads to an increase in intrapulmonary pressure.

During inspiration, their is an increase in the volume of the thoracic cavity. Air moves from high pressure to low pressure so during inhalation intrapulmonary pressure should be low so that there is the proper exchange of gases during inspiration and vice verse during exhalation.
