The colloidal state is very widespread in biological systems and in many practical situations. Basically a colloid consists of two distinct phases, a continuous phase (the dispersion medium) and a particulate phase, where the particles generally have dimensions ranging between 20 and 2000 Å (2 and 200 nm).
