Question

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 has no effect on the exchange of oxygen and carbon dioxide decreases the amount of oxygen and carbon dioxide that can be exchanged. increases the likelihood of infection in the respiratory system

Explanation:

The respiratory membrane is where gas exchange (oxygen and carbon dioxide) occurs. A larger surface area provides more space for this exchange. Mucus production is related to other parts of the respiratory system's functions like trapping particles. A larger surface area doesn't decrease gas exchange (it's the opposite - more area means more exchange can happen), and it doesn't directly increase infection likelihood. The key is that surface area affects the amount of gas that can be exchanged.

Answer:

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