Exchange Surfaces Substances Animals Blood Adapted Maximise Effectiveness

Exchange surfaces are adapted for maximum effectiveness through a thin membrane, a large surface area, abundant blood vessels, and ventilation systems.

Exchange surfaces are adapted with a thin membrane, large surface area, blood vessels, and ventilation to maximize diffusion effectiveness.

Front How are exchange surfaces adapted to maximise effectiveness?
Back
  • Thin membrane so substances have a short diffusion pathway
  • Large surface area so many substances diffuse at one
  • Exchange surfaces in animals have lots of blood vessels to get stuff into and out of the blood quickly
  • Gas exchange surfaces in animals are ventilated so air moves in and out
