Ultrastructural correlation of water reabsorption in isolated rat cauda epididymidis

Experientia. 1978 Apr 15;34(4):485-7. doi: 10.1007/BF01935943.


Electron microscopic study was made on the water reabsorption of the epithelial cells of the rat cauda epididymidis. It was shown that when the epididymal duct was reabsorbing water at a maximal rate, widely dilated intercellular spaces were seen. It is suggested that the standing gradient model of water reabsorption first proposed for the gall bladder may also operate in the cauda epididymidis.
