In the present study, we examined the ultrastructure of the hindgut of <jats:italic>Drosophila<\/jats:italic> larvae, with special reference to the domains, in order to determine whether or not the domains are morphologically distinct functional units. Each domain showed specific ultrastructural features that suggested specific corresponding functions. According to the morphological features, terms are proposed for each domain: the imaginal ring; the \u201cpylorus,\u201d which has a thick cuticular layer and well\u2010developed sphincter muscles; the \u201clarge intestine,\u201d which occupies a major middle portion of the hindgut and has a unique dorsal and ventral subdivision; \u201cborder cells,\u201d which delineate the anterior and posterior borders of the large intestine and the border between the dorsal and ventral domains of the large intestine; and the \u201crectum,\u201d which is situated at the posterior end of the hindgut and has a thick cuticular layer and sphincter muscles. The morphological features indicate that the large intestine has active absorptive activities. The domains, which have been distinguished by gene expressions, were demonstrated to be functional tissue units of the gut. J.
