Vasopressin Secretion

Meaning

Vasopressin secretion is the highly regulated release of the peptide hormone vasopressin, also known as antidiuretic hormone or ADH, from the posterior lobe of the pituitary gland into the systemic circulation. This crucial release is primarily stimulated by increases in the osmolality of the plasma or significant decreases in overall blood volume. The hormone plays an indispensable role in maintaining the body’s fluid balance, regulating plasma tonicity, and contributing to blood pressure homeostasis.
