What is breathing?
The process of intake of oxygen and exhale of carbon dioxide. The organs involved in breathing are called lungs.
According to the question, the passage of oxygen in the lungs will be:- larynx, trachea, bronchi, and capillaries.
In the second question, increased surfaces are for the gas exchange with the capillaries.
In the third, question, the correct answer is option A which is A decrease in air pressure within the lungs that allows air to flow in.
Hence, the correct answer is mentioned above.

B. warm and clean the air before it moves to the alveoli
C. increase surface area for gas exchange with the capillaries
D. decrease pathogens in the air before it moves to the alveoli
3. How does air pressure control expiration?
A. A decrease in air pressure within the lungs allows air to flow in.
B. An increase in air pressure within the lungs allows air to flow out.
C. A decrease in air pressure within the lungs causes them to contract.
D. An increase in air pressure within the lungs causes them to expand.
