Slide 2 - Tekstslide

Goals 
can describe how gas exchange occurs in various different groups of animals.

Slide 3 - Tekstslide

Fish
Gills = breathing organs of fish
  • Gill arch
  • Gill filament
  • Lamellae = thin filaments containing capillaries 

Oxygen goes to the blood in the gill lamellae.
Carbon dioxide goes to the water that flows along the gill lamellae.

Slide 4 - Tekstslide

Countercurrent exchange system

exchange of substances between two flowing liquids or gases, such as oxygen and carbon dioxide, flowing in opposite directions to each other

Slide 5 - Tekstslide

Slide 6 - Video

Insects
Tracheae= breathing tubes within an insect. 
  • Spiracles = holes on the sides of an insect’s body where air enters and leaves
Oxygen enters the trachea and carbon dioxide leaves the trachea as the abdomen becomes larger and smaller.


Slide 7 - Tekstslide

Unicellulars
Unicellulars don't have a particular respiratory system, as they are just one cell that is directly in touch with the environment.  

Slide 8 - Tekstslide

most worm species breath through their skin.

Slide 9 - Tekstslide

Slide 10 - Video

Birds
Birds have different lungs than humans, as they can't directly move. Instead they have air sacs that can store air, and move air pass the lungs. That way gas exchange can still take place.
