OSMOSIS
the movement of water from a dilute solution to a more concentrated solution, through a partially permeable membrane.
1 of 6
DIFFUSION
the moment of particles from high concentration to low concentration, with the concentration gradient.
2 of 6
ACTIVE TRANSPORT
the movement of particles from an area of low concentration to high concentration, with energy required from respiration, against the concentration gradient.
3 of 6
EXCHANGE SURFACES
-large surface area -thin (short diffusion path) -have a good/efficient blood supply -are ventilated.
4 of 6
ALVEOLUS
oxygen to carbon dioxide
5 of 6
VILLI
mitochondria to supply energy for respiration.
