Gas exchange in insects Flashcards
whats is the system called
tracheal system
what three things does an insect have in its tracheal system
spiracles
tracheae
tracheoles
spiracles function
pores open and close for diffusion
tracheae function
tubes are full with O2 so allow diffusion
tracheoles are branched from and function
branches from tracheae’s
PERMEABLE to allow gas exchange
diffusion
how is a tracheae adapted
the tubes are full of air so quicker diffusion
walls
how is the tracheae adapted
it has thin walls so shorter diffusion distance
amount of them
how is the tracheoles adapted
they are many of them soa short diffusion distance
it also has a large surface area
fluids (during exersize)
how are the tracheoles adapted
in exerzise osmosis occurs
so diffusion happens more quickly through air than on the surface
