This card presents alternative methods for enhancing gas exchange in insects with high oxygen demands, such as mechanical ventilation of the tracheal system and the use of air sacs.
Tato karta uvádí alternativní metody pro zvýšení výměny plynů u hmyzu s vysokými nároky na kyslík, jako je mechanická ventilace tracheálního systému a používání vzdušných vaků.
| Front | Alternative methods to inc gaseous exchange for insects with high O2 demands 3.1.1(f) |
|---|---|
| Back | - mechanical ventilation of tracheal system (air actively pumped into system by thorax’s pumping movements, changing vol of body, changing pressure in tracheae/tracheoles (drawing in or forcing out air) - collapsible enlarged trachea /air sacs (acts as air reservoirs to inc amount of air moved through system, inflated/deflated by movements of thorax |
