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 ...

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 ...

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 ...
