Absorption: the process of taking substances from the gastrointestinal tract into the interior of the body. Active transport: transport of substances across a cell membrane with the aid of a carrier molecule and the expenditure of energy. Adenosine triphosphate: high-energy molecule that the body uses to power activities that require energy. Antigen: foreign substance that, when introduced into the body, stimulates an immune response. Antibody: protein, released by a type of lymphocyte that interacts with and deactivates specific antigens. Atom: the smallest unit of an element that retains the properties of the element. Arteries: transport blood and dissolved substances away from heart. Bile: digestive fluid made in the liver and stored in the gallbladder that is released into the small intestine, where it aids in fat digestion and absorption. Neutralizes the acid in the chyme, making the environment in the small intestine neutral or slightly basic rather than acidic, as in the stomach.
