Animal Gas Exchange Systems
Animal Group /
Insect- locust
example
What are the habitats Air – land, flight, on
of the animal?
water (air breathing)
What is the gas
exchange surface?
Thin membrane at
end of tube in direct
contact with cell
Tracheal system
What is the gas
exchange organ
called?
What habitats are the Air
organs restricted to?
Fish- kahawai
Mammal- sheep
Under water (water
breathing)
Air – on land, in the sea
(air breathing)
Surface of lamella –
thin membrane in
water
Gill
Wet moist membrane in
alveolus
Lung (and alveolus)
water
Air
What is exchanged?
Oxygen, carbon
dioxide
Oxygen, carbon
dioxide
Food, O2, CO2,
hormones, heat
What is the method
of exchange?
Diffusion
Counter current
exchange
Diffusion with moving
blood supply
Is the GE system
separated from food
transport?
Name the parts of
the GE system.
yes
no
No
Spiracle, trachea,
tracheole, air sac,
thin membrane
Gill, buccal cavity,
lamella, mouth,
opercular
Spiracle - trachea,
tracheole - thin
membrane
Is there an O2 carrier No
and what is it called?
Mouth - buccal cavity
– Gill – lamella opercula
Yes - haemoglobin
Nasal cavity, trachea,
bronchus, bronchiole,
alveoli, diaphragm,
epiglottis, intercostals
Nasal cavity – trachea –
bronchus – bronchiole alveoli,
Yes - haemoglobin
What size of animal
does the GE system
suit?
How is O2 delivered
to the cells?
Small and simple
Small to medium complex
Small to very large very
complex
Tracheal system –
diffusion directly
through membrane
Abdominal muscles
By capillaries
By capillaries
Jaw muscles, Heart
pumping blood
Are there any special
GE modifications?
Air sacs
Are there any aids to
GE?
Abdominal muscles
Counter current
exchange –
gills/blood
Water keeps
membrane moist
Intercostals muscles,
diaphragm, heart, all
involuntary
Large surface area in
lungs
List the sequence of
the GE system
What muscles are
involved in GE?
What controls the GE Brain
system?
Respiratory centre in
the brain
Animal Group /
example
Fish- kahawai
Insect- locust
Mucous covered
membrane
Respiratory centre in
the brain – detects CO2
levels
Mammal- sheep
