inflammation-the response of the tissues of the body to irritation or injury. The signs of inflammation are redness, heat, swelling, and pain.
inflammatory bowel diseases (IBD)-diseases that cause irritation and ulcers in the intestinal tract. Crohn's disease and ulcerative colitis are the most common inflammatory bowel diseases.
influenza (Also called the flu.)-a viral respiratory tract infection. The influenza viruses are divided into three types: A, B, and C.
informed consent-a legal document that explains a course of treatment, the risks, benefits, and possible alternatives; the process by which patients agree to treatment.
infusion therapy (Also called intravenous therapy.)-the introduction of fluid other than blood into a vein.
inguinal hernia-part of the small intestine that pushes through an opening in the abdominal muscle, causing a bulge underneath the skin in the groin area.
