Transcript of Chrons Disease
Overview The digestive system is made up of the digestive tracta series of hollow organs joined in a long, twisting tube from the mouth to the anusand other organs that help the body break down and absorb food (see figure).
Organs that make up the digestive tract are the mouth, esophagus, stomach, small intestine, large intestinealso called the colonrectum, and anus. Inside these hollow organs is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food. The digestive tract also contains a layer of smooth muscle that helps break down food and move it along the tract.
Two “solid” digestive organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes called ducts. The gallbladder stores the liver’s digestive juices until they are needed in the intestine. Parts of the nervous and circulatory systems also play major roles in the digestive system.
What is the Digestive System? Crohn’s disease is an ongoing disorder that causes inflammation of the digestive tract, also referred to as the gastrointestinal (GI) tract. Crohn’s disease can affect any area of the GI tract, from the mouth to the anus, but it most commonly affects the lower part of the small intestine, called the ileum. The swelling extends deep into the lining of the affected organ. The swelling can cause pain and can make the intestines empty frequently, resulting in diarrhea. How does Crohn's
Disease effect the
Digestive System?? The Immune system The immune system is the body's defense against infectious organisms and other invaders. Through a series of steps called the immune response, the immune system attacks organisms and substances that invade body systems and cause disease.
The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. The cells involved are white blood cells, or leukocytes, which come in two basic types that combine to seek out and destroy disease-causing organisms or substances.
The immune system is composed of various cells and proteins. Normally, these protect the body from infection. In people with Crohn's disease, however, the immune system reacts inappropriately. Researchers believe that the immune system mistakes microbes, such as bacteria that is normally found in the intestines, for foreign or invading substances, and launches an attack. In the process, the body sends white blood cells into the lining of the intestines, where they produce chronic inflammation. These cells then generate harmful products that ultimately lead to ulcerations and bowel injury. When this happens, the patient experiences the symptoms of IBD. Chrohns Disease and how it
effects the Immune System. excretory system The excretory system involves a process which removes unwanted products from the body's chemistry. In general, excretion is the process of separating wastes from the body fluids and eliminating them. Examples include the removal of carbon dioxide in the air we exhale, and unwanted nitrogen in sweat, nails and hair. (Don't confuse excretion with defecation. Defecation is getting rid of undigested foods from the body... via the colon.) What is the Excretory System? Kidney stones, usually composed of either calcium oxalate or uric acid, are much more common in people with IBD than they are in the general population. Kidney stones are especially a problem in patients who do not absorb fat in their small intestine due to symptomatic Crohn’s disease and those who have had multiple surgeries due to Crohn’s disease with removal of bowel.
