Alveolar pressure has the following characteristics (select all that apply): O It is always a negative pressure relative to atmospheric pressure. As the volume of the lungs decreases, the alveolar pressure within the lungs decreases. OAs the volume of the lungs increases, the alveolar pressure within the lungs decreases. OIt can be a negative pressure or a positive pressure relative to atmospheric pressure. O It is the pressure within the space between the parietal and visceral pleura.

Match the sequence of statements with the correct structures as you trace air through the respiratory system. Group of answer choices Air first enters our body through the __________, better known as the nostrils. It then proceeds into the __________, a small, rounded entry-region of the nasal cavity. While in the nasal cavity, the air is humidified, warmed, and filtered because turbulence is created by the _________…
