Abstract
The adenohypophysis receives its blood supply from two portal venous systems through fenestrated venules which are structurally similar to capillaries (Page 1986). The orthodox view that there is no direct arterial supply has recently been challenged (Gorczyca and Hardy 1987) but it is accepted that any arterial supply only serves a small minority of the gland. This unusual anatomy suggests a fundamental difference in the dynamics of adenohypophysial perfusion when compared to other organs in the body and assumes particular importance because of the dual nutritive and neuroendocrine functions of the pituitary portal blood supply.
