Intestines and bowel are two different words for the same organs.
The digestive tract starts at the mouth, descends via the esophagus to the stomach and from the stomach across the body to the beginning of the small intestine from thence to the colon, the rectum and the anus.
The first part of the small intestine (bowel) is referred to as the duodenum, the second part is called the jejunem which then proceeds to the third part of the small bowel (intestine) called the ileum which is the longest part of the small intestine (bowel).
The distal (far) end 3 feet of the small intestine (bowel) is referred to as the terminal ileum.
The terminal ileum passes thru the ileocecal valve into the cecum which is the beginning of the large intestine (bowel) which is called the colon. The appendix drops off the cecum. The cecum runs into the ascending colon which runs up the right side of our body then turns across the body in what is often referred to as the transverse colon to the left side of our body where it turns downard and is then referred to as the descending colon which then turns back towards the center of our body in a section referred to as the sigmoid colon which then turns downward in the center of our body as the rectum which runs into the anus or anal opening where our feces are expelled.
So - in via the mouth, esophagus, stomach, duodenum, jejunem, ileum, ileocecal valve, cecum, ascending colon, transcending colon, descending colon, sigmoid colon, rectum, anus and out.
Ulcerative colitis is found only in the colon and can be cured by surgery. UC affects only the inner linings of the colon and spreads evenly.
Crohn's disease can strike anywhere in the digestive tract from mouth to anus. It can work its way thru the entire wall of the intestine (bowel) and perforate. Crohn's disease usually spreads unevenly, skips and jumps, leaving healthy intestine between areas of disease activity. The most common area for Crohn's disease to strike is the terminal ileum near the ileocecal valve.
I can think of "funner" things to have than Ulcerative colitis or Crohn's disease. *sigh*
