Anatomical and tissue-level structures

Anatomical and tissue-level structures refers to the physical organization of a biological organism, encompassing tissues, organs, and organ systems (NIH NCI Thesaurus). This term does not represent a single molecular target, such as a protein or enzyme, but rather the biological context in which therapeutic targets operate (MeSH). In drug development, understanding these structures is essential for evaluating drug distribution, metabolism, and tissue-specific toxicity (StatPearls). For instance, the structural integrity of the renal tubules or the alveolar-capillary membrane determines the pharmacokinetic profile of many systemic therapies. Because this entry represents a high-level category of biological organization rather than a specific molecule, it is not a direct target for pharmacological intervention. Instead, it serves as a framework for medical indexing and the study of systemic diseases.
