Question

which of the following increases the rate of gas exchange across the respiratory membrane? multiple choice decreased surface area of the respiratory membrane increased fluid in the alveoli increased surface area of the respiratory membrane increased connective tissue in the alveolar wall increased thickness of the respiratory membrane

Explanation:

The rate of gas exchange across the respiratory membrane is directly proportional to its surface area. A larger surface area provides more space for gas - oxygen and carbon dioxide - to diffuse across. Decreased surface area, increased fluid in the alveoli, increased connective tissue in the alveolar wall, and increased thickness of the respiratory membrane all impede gas exchange.

Answer:

C. Increased surface area of the respiratory membrane
