Histologically the rectum is similar to the rest of the large intestine with its usual structure: mucosa, submucosa, muscularis and serosa/adventitia. You can easily remember these layers using the mnemonic 'M.S.M.S'. Simple columnar epithelium (with microvillous border) Epithelium simplex col...
large intestine- beginning with the cecum and ending with the rectum; includes the cecum and the colon and the rectum; extracts moisture from food residues which are later excreted as feces anus- the excretory opening at the end of the alimentary canal ...
The cells in the rectal pads have a complicated array of intercellular junctions associated with the active sites of ion secretion and resorption. The evolution of a rectal structure permitting the formation of a urine hyperosmotic to the hemolymph was, along with the evolution of a waxy cuticle,...
