the process of absorbing or the state of being absorbed

physiol

1. normal assimilation by the tissues of the products of digestion

2. the passage of a gas, fluid, drug, etc, through the mucous membranes or skin

physics a reduction of the intensity of any form of radiated energy as a result of energy conversion in a medium, such as the conversion of sound energy into heat

immunol the process of removing superfluous antibodies or antigens from a mixture using a reagent

Biology��The movement of a substance, such as a liquid or solute, across a cell membrane by means of diffusion or osmosis.

Chemistry��The process by which one substance, such as a solid or liquid, takes up another substance, such as a liquid or gas, through minute pores or spaces between its molecules. A paper towel takes up water, and water takes up carbon dioxide, by absorption.

Chemistry��Compare adsorption

Physics��The taking up and storing of energy, such as radiation, light, or sound, without it being reflected or transmitted. During absorption, the energy may change from one form into another. When radiation strikes the electrons in an atom, the electrons move to a higher orbit or state of excitement by absorption of the radiation's energy.
