Question
Chapter 42.5, Problem 2CC
Summary Introduction
To explain: How gas exchange requirements of an earthworm are responsible for their coming out on the earth’s surface after heavy rains.
Concept introduction:
The process of gaseous exchange between the circulatory system and the environment is called respiration or respiratory exchange. For earthworms as well as some amphibians, the skin serves as the respiratory organ.

QUESTION 6 Mammalian lungs are very different in structure compared to amphibian lungs. The lungs of mammals have highly complex branching patterns of airways. The lungs of amphibians are simpler and more sac-like. Over all, the lungs of mammals are capable of much greater rates of gas exchange compared to amphibians. Why is this? O The more complex structure provides more surface area across which gas exchange can occur. O A complex structure means that gases have more contact time with gases compared to a simpler structure. O Mammalian lungs are usually much bigger relative to their bodies compared to amphibian lungs.
