Explanation:
Absorption, in general sense, is the act or process of absorbing or assimilating. In biology, absorption pertains particularly to the process of absorbing or assimilating substances into the cell or across the tissues and organs. It is done through diffusion or osmosis. For instance, absorption through the skin is a way through which substances can enter the body. Referred to as dermal absorption, the process of absorbing upon exposure to certain toxic substances is one of the means (others, via inhalation and ingestion) through which they could enter the body. Dermal absorption may also be used as a route of administration for certain medications. Another example of biological absorption is the absorption of digested food specifically through the wall of the intestine (especially, the small intestine). The digested food in the small intestine passes through the walls of the small intestine into the blood vessels by diffusion or by active transport.
