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.
