In a medical context, 'distribution' refers to the pattern of branching and anatomical structures, which encompasses how substances, such as medications, move throughout the body after they enter the bloodstream. This concept is essential for understanding how drugs reach various tissues and organs, influencing their efficacy and metabolism.

Distribution considers factors like blood flow to specific organs, the ability of a drug to cross cell membranes, and the binding of drugs to proteins in the bloodstream. A thorough understanding of distribution helps healthcare providers predict how well a medication will work, its therapeutic effects, and potential side effects based on its anatomical pathways.

Other options describe different pharmacological processes: absorption focuses on how drugs enter the bloodstream, administration pertains to the methods used to deliver medications, and elimination deals with how substances are removed from the body. Each of these processes is important, but they do not fully capture the concept of distribution in the same anatomical and physiological context.
