Pregunta 1
Pregunta
As their main gas exchange organ, fish use [blank_start]gills[blank_end]. Their structure consists of [blank_start]an arch[blank_end] from which [blank_start]filaments[blank_end] project. Each filament contains many [blank_start]lamellae[blank_end], through which capillaries run. This is the site at which gas exchange takes place. The blood flows through the capillaries in the [blank_start]opposite[blank_end] direction as/to the water that flows through the gills, creating a [blank_start]countercurrent[blank_end] exchange. This ensures there is a favourable gradient in [blank_start]water potential[blank_end] between the water and the blood.

Pregunta 4
Pregunta
Which of the following correctly explain how gas moves dynamically throughout the insect's gas exchange system? Check all that apply.
Respuesta
-
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.
