The Capillary Endothelium in the Rete Mirabile of the Swimbladder of the Eel (Anguilla anguilla): Functional and Ultrastructural Aspects
The rete mirabile of the swimbladder of the eel is a network of straight capillaries, one against the other, in which an arterial capillary alternates with a venous capillary. The function of these capillaries is to allow the swimbladder to concentrate oxygen by a hairpin countercurrent multiplicati...
