What respiration for fish and why?

• Countercurrent exchange.

  Aquatic enviroment.

• Crosscurrent exchange. Aquatic environment.

• Clockwisecurrent exchange. Courtship.

What respiration does the amphibian have and why?

• Positive pressure breathing and countercurrent exchange. They have ribs.

• Positive pressure breathing and cutaneous respiration. Lungs but no ribs & courtship is in a moist environment.

• Cutaneous respiration. They have ribs.

What are the respiration of reptiles and mammals and WHY?

• Negative Pressure breathing. Gained ribs because they are large terrestrial animals with dry skin (no cutaneous resp) and amniotic egg (offspring on land).

• Negative pressure breathing. They are at a higher altitude.

• Positive pressure breathing. Gained ribs because they are large terrestrial animals with dry skin (no cutaneous resp) and amniotic egg (offspring on land).

• Positive pressure breathing. They are at a higher altitude.

Gas exchange occurs on the ____ of the fish.

• gill arch and filaments, lamellae

• operculum

• scales

• swim bladder

Where does gas exchange occur in reptiles and mammals

• alveloi

• heart

• sternum

• amniotic egg

Why does the bird have a more efficient respiratory system than the mammals?

• flying at a lower altitude makes air more available

• flying at a high altitude where there is less air available

• they are endoderms

Why do gills not function in a terrestrial environment?

• Dessication, need to be wet

• Structural support, gills will collaspe

• The do function in a terrestrial environment

• The operculum is exposed

Ways to maximize gas exchange through diffusion.

• Increase SA

• Reduce distance, be thin

• maintain concentration gradient

• body movements
