Also called antibody. inflammation Redness, heat, pain, and swelling from injury or infection. intestine The organ that food passes through after leaving the stomach. intravenous Given by a needle or tube inserted into a vein. karyotyping A process that examines a map, or karyotype, of a cell’s chromosomes—long strands of bundles of coded instructions for controlling cells.
