पर्याय
Ethanol
Carbon dioxide
Acetic acid
Lactic acid

The two organisms which breath only through their moist skin are:
When a person breathes in the air, the air enters into his body through an organ A having two holes B in it. The air then passes through the pharynx and larynx and enters into tube C. The tube C divides into two smaller tubes D at its lower end. The two smaller tubes are attached to two respiratory organs E. Each smaller tube divides inside the organs E to form a large number of still smaller tubes called F. The smallest tubes F have air-sacs G at their ends in which gaseous exchange takes place in the body of the person. What are A, B, C, D, E, F, and G?
