Which of the following describes Boyle's law?
A)An increase in thoracic volume causes an increase in intrapulmonic pressure.
B)There is no relationship between intrapulmonic pressure and thoracic volume.
C)An increase in thoracic volume decreases intrapulmonic pressure.
D)An increase in thoracic volume forces air out of the lungs.

Question

Quizplus · Accepted Answer

Boyle's law describes the relationship between gas pressure and volume. According to the law, an increase in thoracic volume (during inspiration) results in a decrease in intrapulmonic pressure, which draws air into the lungs. This relationship is crucial for normal breathing. Choice A is incorrect because an increase in thoracic volume causes a decrease, not an increase, in intrapulmonic pressure. Choice B is also incorrect because there is indeed a relationship between intrapulmonic pressure and thoracic volume. Choice D is incorrect because an increase in thoracic volume allows air to enter the lungs, not to be forced out.
