Animal Transport Systems
Group
What is the habitat?
Insect- locust
Fish- kahawai
Air breathing – land and Water breathing - under
air and on water
water
Mammal- sheep
Air breathing – on land,
air and under water
What is transported?
Food, hormones
Food, Oxygen, carbon
dioxide, hormones
Food, Oxygen, carbon
dioxide, hormones, heat
Is circulatory system
open or closed?
Open circulatory system
- Body is fluid filled
Closed circulatory
system
Closed circulatory
system
Is Oxygenated and
deoxygenated blood
separate or mixed?
What is the transport
medium?
Blood is not oxygenated
Oxygenated and
deoxygenated blood is
mixed
Oxygenated and
deoxygenated blood is
kept separate
Haemolymph
blood
blood
How many circuits are
there?
Two circuits – heart to
None
One circuit of the body lungs to heart and heart
to body to heart
What are the pumping Dorsal vessel – tubular Heart has 2 chambers – Heart has 4 chambers –
organs?
heart
atrium and ventricle
left and right atrium and
ventricle
What is the order of
Rhythmic pumping from
Atrium to ventricle to
Right atrium (RA) to R
pumping?
tail to head
gills to body cells to
ventricle to lungs to LA
sinus venosus to atrium
atrium to LV to body
What are the pigments /
Haemoglobin – red
Haemoglobin – red
cells?
There are no pigments
blood cells
blood cells
What are the important
vessels in the system?
Forward to the head out
via the dorsal aorta
Arteries, arterioles,
capillaries, venules,
veins
Through arteries with
thick walls to the gills
Arteries, arterioles,
capillaries, venules,
veins
Through arteries to the
lungs (deoxygenated) or
the body (oxy)
Dorsal vessel
Where does the blood
flow from the pump?
How are nutrients
delivered to the cells?
Cells bathed in fluid
capillaries
capillaries
How does blood get to
the pump?
In through the ostia
In via veins
In via veins
What is the pressure in
the transport system?
Are there any aids to
blood flow?
Group
There is little pressure
Leaves heart under high Leaves heart under high
pressure and returns
pressure – 2 circuits –
sluggish via gills/ body
returns lower pressure
Peristaltic contractions Water pressure and tail Elastic arteries and non
of the muscles in the
movement aid blood
return valves in veins
