Alveolar cells constantly transport Na + ions from the apical to the basolateral side. Na + enters the cells through epithelial Na + channels (ENaC) in the apical membrane and is extruded by ...

This ultrastructural study of the dorsal ciliated organ of Nereis virens shows that the highly folded ciliated epithelium of the organ has characteristics of a transporting epithelium. Microvilli, ...

Background and aims: Sodium transport plays a crucial role in alveolar fluid clearance (AFC), where sodium enters the alveolar epithelial cells through apical sodium channels (ENaC) and is extruded by ...

The epithelium is a type of tissue that covers many different surfaces on the inside and the outside of your body. Epithelial cells are packed tightly together and serve as a barrier between the ...

In general, ionic regulation will depend on active transport by epithelia and also on the permeability properties of these tissues. Passive permeability has recently been studied in the hindgut of the ...
