Would the trachea collapse when you were exhaling if there were no rings of cartilage in its walls

The answer is YES. The trachea would collapse during exhaling due to the negative pressure developed as a result of evacuating air from the lungs. Physics dictates that the area with high pressure (outside environment) pressure on the region with low air pressure (in the lungs during exhalation).

the answer is trees if i'm not mistaken

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
