The document discusses how different types of animals breathe. Land animals like mammals, birds, and insects breathe in oxygen through nostrils or breathing holes into their lungs. Fish breathe through gills that extract oxygen from water flowing over them. Amphibians can breathe through their skin in water and lungs on land. Aquatic mammals like dolphins surface and breathe through blowholes.

2. LAND ANIMALS
MOST MAMMALS
Breathing in oxygen from the air through their nostrils into
their lungs

3. LAND ANIMALS
BIRDS
Breathing in oxygen from the air through their nostrils into
their lungs

4. LAND ANIMALS
INSECTS
Breathing in oxygen from the air through their breathing
holes

5. FISH
● Using gills which are under the gill
covers to help breath in underwater
● The gills have large surface with a rich
supply of blood
● Fish take in water through their mouth.
As water flows past the gills, dissolved
oxygen in the water enter the blood in
the gills and is transported to other
parts of the body.
AQUATIC ANIMALS

6. AMPHIBIANS (frogs)
● Breathing in oxygen from the air through their nostrils into
their lungs WHEN ON LAND
● Breathing in oxygen through their moist skin WHEN IN
WATER
AQUATIC ANIMALS

7. MAMMALS (dolphins/whales)
● Coming up to the water surface to take in air and
breathing in oxygen from the air through blowholes.
