Explain why pure liquids and solids can be ignored while writing the equilibrium constant expression

Explain why pure liquids and solids can ignored while writing the equilibrium constant expression?

Assertion: No term in the concentration of a pure solid or a pure liquid apperas in an equilibrium constant expression. Reason: Each pure solid or pure liquid is in a phase by itself and has a constant concentration at constant temperature.
