Physicochemical fluid balance

Physicochemical fluid balance" refers to the integrated physiological mechanisms by which the body regulates the amount, distribution, and composition of its water and solutes to maintain homeostasis. This process involves behavior (e.g., thirst), hormones (such as vasopressin/antidiuretic hormone, aldosterone, and atrial natriuretic peptide), the action of various cellular and molecular components (like aquaporin channels, sodium-potassium pumps, and osmoreceptors), and organ-level control (primarily by the kidneys, but also involving the brain and cardiovascular system). Disturbances in physicochemical fluid balance contribute to a variety of clinical conditions, but the term is not a molecular entity or a valid therapeutic "target" in itself.
