Fish and Insect Gas Exchange

Question 1 of 6

1

Select from the dropdown lists to complete the text.

As their main gas exchange organ, fish use ( gills, lungs, spiracles, capillaries ). Their structure consists of ( an arch, a loop, a spiral, filaments ) from which ( filaments, arches, alveoli, spiracles ) project. Each filament contains many ( lamellae, grana, stomata ), through which capillaries run. This is the site at which gas exchange takes place. The blood flows through the capillaries in the ( opposite, same ) direction as/to the water that flows through the gills, creating a ( countercurrent, current, anti-current, monocurrent ) exchange. This ensures there is a favourable gradient in ( water potential, osmotic pressure, oncotic pressure, water flow ) between the water and the blood.

Which of the following correctly explain how gas moves dynamically throughout the insect's gas exchange system? Check all that apply.

Select one or more of the following:

Gases move down a concentration gradient towards respiring tissue.
Muscle movements squeeze and 'pump' air throughout the tracheoles and tracheae.
Lactate in respiring tissues draws in water, which is followed by gas.
Insects have rib-like cartilage structures that rotate, acting like a spiral that pumps air.
