lo 4.2. what is the importance of the respiratory membranes surface area?
allows a greater amount of oxygen and carbon dioxide to be exchanged.
reduces the amount of mucus production in the respiratory system
decreases the amount of oxygen and carbon dioxide that can be exchanged.
increases the likelihood of infection in the respiratory system
has no effect on the exchange of oxygen and carbon dioxide

Explanation:

The respiratory membrane is where gas exchange (oxygen and carbon dioxide) occurs. A larger surface area provides more space for this exchange to happen. Mucus production, infection likelihood, and statements about no effect or decreased exchange are not related to the role of surface area in gas exchange.

Answer:

Allows a greater amount of oxygen and carbon dioxide to be exchanged.
