A chain of very large cuboidal cells forming a wide central lumen in which food arrives from the posterior pharynx, is digested, and from which waste products proceed to the rectum. Intestinal rings form in groups of two and four cells surrounding the common lumen; thus the epithelium is only one cell deep at any point, with neighboring cells firmly secured to their neighbors by apical adherens junctions. These cells have very large nuclei and many large vacuoles, yolk granules, and other inclusions; the latter increase in number and electron density as the animal ages. |

a single, H-shaped cell which lies just above the anus and connects the roof of the anal canal to the dorsal bodywall; its contractions act to increase the size of the anal opening by lifting the roof of the rectum and hence facilitate expulsion of intestinal contents. |

The components of the gonad that are separate from the germline proper. In hermaphrodite, these include five tissues which are all derived from the somatic primordium : the distal tip cells, the gonadal sheath, the spermatheca, the spermatheca-uterine valve (sp-ut) and the uterus. |
