Q

Label these two regions and identify the structure and its function that separates the them

A

Thoracic cavity and Abdominal cavity are separated by the Diaphragm. The diaphragm is a muscle that not only separates these two regions but as it contracts it increases the volume of the thoracic cavity and draws air into the lungs.

Q

What groups make up the amniotes

A

Reptilia

Mammalia

Aves

125
Q

How do amphibians and reptilians differ

A

Amphibians are tied to the water by reproduction because they do not produce dry resistant eggs (amniotic eggs).
