The respiratory tract must be open to the environment to allow exchange of gas between air and blood. This renders lhe lungs susceptible to colonization and infection by foreign organisms. It is necessary for lhe lower respiratory tract to have mechanisms to contain and control such foreign material. The gas exchange surface of lhe lung must be thin, delicate and permeable, rhus the mechanisms ...

The gastroduodenal mucosa is a dynamic barrier restricting entry of gastric acid and other potentially hostile luminal contents. Mucosal HCO3(-) is a key element in preventing epithelial damage, and knowledge about HCO3(-) transport processes, including the role of the cystic fibrosis transmembrane conductance regulator channel, and their neurohumoral control are in rapid progress.
