  1. Which one of the following statements is incorrect?
    1. The presence of non-respiratory air sacs, increases the efficiency of respiration in birds
    2. In insects, circulating body fluids serve to distribute oxygen to tissues
    3. The principle of countercurrent flow facilitates efficient respiration in gills of fishes
    4. The residual area in lungs slightly decreases the efficiency of respiration in mammals
Correct Option: B

In insects circulating body fluid called hameolymph does not help in the circulation of respiratory gases for the body. It only circulates the food and nutrients to the different body parts. Distribution of oxygen (respiration) takes place through small air chambers called spiracles.
