Segregan [[glicosaminoglicano]]s para protexer o revestimento interno do bronquiolo e diversas proteínas con propiedades similares a un [[surfactante]]. Cando os bronquios se van ramificando e estreitando orixinando bronquiolos, decrece progresivamente o número de [[célula caliciforme|células caliciformes]], polo que deixa de producirse mucina, que é substituída por estas outras secrecións.
Clara cells are found in the ciliated simple epithelium. These cells may secrete [[Glycosaminoglycan|glycosaminoglycans]] to protect the bronchiole lining.Bronchiolar cells gradually increase in number as the number of goblet cells decrease.
 
They are also known as "bronchiolar exocrine cells".<ref name="PapadakosLachmann2007">{{cite book|author1=Peter J.
