Question
Select all of the options that best complete the following sentence. When we inhale, the diaphragm contracts, causing:air to be forced out of the lungsthe pressure in the lungs to decreasethe lungs to shrinkthe lungs to expand
Solution
The correct options that best complete the sentence are:
- the pressure in the lungs to decrease
- the lungs to expand
When we inhale, the diaphragm contracts and moves downward. This increases the space in the chest cavity, into which the lungs expand. This expansion lowers the pressure in the lungs. As the pressure in the lungs drops, air is drawn in through the nose and mouth and down into the lungs.
