Ulcerative colitis
Painful condition in which ulcers form in the colon and rectum
Volvulus
Twisting of the intestine that can cause obstruction
Colon
Portion of the large intestine extending from the cecum to the rectum
Ascending colon

Transverse colon
Area of large intestine between the ascending colon and descending colon
Descending colon
Section of the large intestine that follows the transverse colon
Sigmoid colon
