Abstract

We have been studying the urinary bladder of the toad, Bufo marinus, as a model transporting epithelium which actively moves sodium from urine to body fluids [1, 2]. The results of two recent studies, which relate to the functional structure of this tissue and to how its permeability properties are modified by vasopressin, will be presented.
