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 free-floating spherical cell lying in the pseudocoelomic cavity of larvae and adult C. elegans which can endocytose many compounds, possibly for immune surveillance. There are six coelomocytes in adult hermaphrodites, and they display prominent cytoplasmic inclusions and vacuoles. |

A fluid-filled space enclosed on the outside by the basal laminae of the bodywall tissues, principally those of the bodywall muscles and the hypodermis. Within this space the digestive tract and reproductive tract lie separately, each enclosed by its own basal lamina. Intercellular signals, nutrients and waste products can travel between all tissues bordering this space. |
