inflammatory response occurs in the small airway. This inflammation causes the release of mediators such as proteases which in turn damage the large airway causing bronchial dilation. This further causes impaired mucus secretion which obstructs the airway due to retention of secretions. Inflammatory scarring replaces the lung functioning and causes bronchiectasis. The inflammation may spread beyond the airways and may cause interstitial pneumonia. The cells which cause inflammation in bronchiectasis

V. Anatomy and Physiology The Urinary Tract The Urinary System rids the body of nitrogenous wastes while regulating water‚ electrolyte‚ and acid-base balance of the blood. Kidneys Kidneys are small‚ dark red organs with a kidney-bean shape lie against the dorsal body wall in a retroperineal position (beneath the parietal peritoneum) in the superior lumbar region. The kidneys extend from T12 to the L3 vertebra; thus they receive some protection from the lower part of the rib cage. Because

breaks down the bolus with highly acidic stomach secretion and is turned into a semi liquid mass called chyme. This process could take 2 to 6 hours depending on the amount of food and type of food. The chyme then moves to the small intestine. The small intestine is 20 feet long and takes 3 to 5 hours for chyme to move through the small intestine. This is where most of the nutrients are absorbed. While moving through the small intestine additional secretions are produced from the liver‚ gallbladder and

defect in the body’s ability to maintain a homeostatic glucose level. The defect may be in insulin secretion‚ insulin action or both. Diabetes can be classified as Juvenile‚ Type 1‚ Type 2‚ or Gestational. Distinction between the different classifications is based on the circumstances present at time of the diagnosis. Defect in insulin secretion Type 1 diabetes is an absolute deficiency in insulin secretion in the pancreatic islets. Type 1 diabetes can be confirmed by serological evidence of an autoimmune
