|large intestine |
The wide lower section of the intestine that extends from the end of the small intestine to the anus. The large intestine acts mainly to absorb water from digested materials and solidify feces. In most vertebrate animals, it includes the cecum, colon, and rectum.
The lower portion of the intestines, which receives a soupy mixture of digested food from the small intestine, reabsorbs most of the fluids, and then passes the resulting solid substance (feces) out of the body through the anus. The large intestine is divided into the cecum, colon, and rectum.
