iliac colon

The iliac colon is a section of the large intestine, specifically the part of the sigmoid colon that extends from the iliac crest (the upper border of the hipbone) to the inner border of the psoas muscle. It is located in the left iliac fossa of the abdomen. This section, like the rest of the colon, is primarily involved in absorbing water and electrolytes from digestive residues and storing fecal material before defecation. The colon itself is the posterior section of the intestine, following the small intestine, and plays a crucial role in the digestive process by absorbing water and electrolytes and producing certain vitamins.123
