Inflammatory bowel disease is condition that involves chronic inflammation in a portion or all parts of the digestive tract. It is often painful and debilitating which can be life-threatening and may lead to risk for colon cancer. With inflammatory bowel disease, the small and large intestines or bowels become inflamed (there is redness or swelling).
Its symptoms include: severe or chronic abdominal pain, diarrhea, sudden weight loss, lack of appetite or rectal bleeding.
It has two major types the ulcerative colitis and Crohn's disease. The primary difference between the two is the parts of the digestive tracts that they affect. Ulcerative colitis causes inflammation and ulcers only the top layer of the large intestine. Whereas, Crohn's disease commonly affects the end of the small intestine (ileum) and the proximal part of the colon. Such inflammation causes swelling and scar tissue that thickens the intestinal wall.

Answer:
All life respires, or breathes. Respiration in mammals is similar to respiration in other air-breathing animals. Respiration extracts oxygen from the air, which is then used by cells. Respiration also carries waste carbon dioxide away from the cells. Although respiration depends on other systems, like the circulatory system, to take oxygen and carbon dioxide to and from cells, the respiratory system has the primary responsibility of bringing oxygen in to a mammal's body and sending carbon dioxide into the atmosphere.
