When the switch of a flashlight is pushed into the ON position, it makes contact between two contact strips, which begin a flow of electricity, powered from the battery. The batteries are connected in such a way that electricity (flow of electrons) runs between the positive and negative electrodes of the battery.

Inflammatory bowel disease (IBD) refers to two different chronic conditions or diseases that may be related, Crohn's disease and ulcerative colitis. Both diseases consist of inflammation of the wall of the bowel or intestines-hence the name-leading to bowel that is inflamed, swollen and that develops ulcers.reatment of IBD depends on the type of IBD-Crohn's disease or ulcerative colitis-the location and extent of the disease, and the severity of the disease. For mild disease activity, anti-inflammatory drugs (aminosalicylates) that work locally on the bowel may be used either orally or as enemas.
