Summary Introduction
Introduction:
In animals, the circulatory system helps in the distribution of nutrients and oxygen from the external environment into the body. In return, it expels waste products and carbon dioxide from the body to the external environment. The circulatory system varies from simple animals to complex animals.

How can aquatic arthropods have larger bodies than their terrestrial counterparts?
A.
Terrestrial arthropods lack a circulatory system.
B.
The circulatory system of aquatic arthropods is more efficient.
C.
Gas exchange across the body surface occurs more readily in aquatic environments.
D.
Buoyancy of the water can support heavier exoskeletons.

Amphibians have three-chambered hearts, which have some limitations when compared to the four-chambered hearts of birds and mammals. Describe a disadvantage of a three-chambered heart (in comparison to a four-chambered heart), and one way in which amphibians are able to compensate for it.
