large intestine n. The portion of the intestine that extends from the ileum to the anus, forming an arch around the convolutions of the small intestine and including the cecum, colon, rectum, and anal canal. Also calledlarge bowel.
The large intestine extends from the ileocaecal (ileocolic) junction, where it begins as the caecum, via the ascending, transverse, descending and sigmoid parts of the colon, rectum and anal canal, to the anal verge (the junction of perineal skin and anal mucosa at the anus). Understanding...

Arterial supply to the large intestine arises from the branches of the superior mesenteric artery (the ileocolic, right colic, and middle colic arteries) which supply the cecum, ascending colon, and proximal two thirds of the transverse colon. The inferior mesenteric artery supplies the remainder of...
Emma Marchionatti, in Comparative Veterinary Anatomy, 2022 Introduction The large intestine (LI) is aboral to the small intestine and consists of the cecum, colon, and rectum. The entire intestinal tract is confined to the right abdominal cavity due to the presence of the large rumen. The LI...
Unlike the small intestine, the large intestine mucosa lacks villi. The glands (or crypts of Lieberkühn) contain large amounts of mucin-secreting goblet cells (Standring, 2016). Complete AnatomyThe world's most advanced 3D anatomy platform See these models in 3D with C...
Function The large intestine has 3 primary functions: absorbing water and electrolytes, producing and absorbing vitamins, and forming and propelling feces toward the rectum for elimination. By the time indigestible materials have reached the colon, most nutrients and up to 90% of the water has been...
