Circumventricular organs an integral part of neuroendocrine function. The highly permeable capillaries allow the CVOs to act as an alternative route for peptides and hormones in the neural tissue to sample from and secrete to circulating blood. CVOs also have roles in body fluid regulation, cardiovascular functions, immune responses, thirst, feeding behavior and reproductive behavior. CVOs can be classified as either sensory or secretory organs serving homeostatic functions and body water balance. The sensory organs include the area postrema (AP), the subfornical organ (SFO) and the vascular organ of lamina terminalis, all having the ability to sense signals in blood, then pass
