Final answer:
Bowel inflammation, diverticulitis, and hemorrhoids, which affect the large intestine and rectum, are common causes of bleeding in the lower GI tract.
Step-by-step explanation:
Bowel inflammation, diverticulitis, and hemorrhoids are common causes of bleeding in the C. lower GI tract. These conditions typically affect the large intestine and rectum. Diverticulitis involves the inflammation of pouches in the large intestine's wall, while inflammatory bowel disease includes conditions like Crohn's disease and ulcerative colitis that often cause inflammation of the colon and rectum. Hemorrhoids, which are swollen veins in the lower rectum and anus, can also lead to bleeding.
