An average healthy dog drinks about 1/2 to 1 ounce of water per pound of body weight per day. The amount of water your dog is drinking is an important piece of information to share with your veterinarian and can help avoid unnecessary testing. Keep in mind that dogs are very sloppy, inefficient drinkers.
Barrett's esophagus overview. Barrett's esophagus is a condition in which the esophagus, the muscular tube that carries food and saliva from the mouth to the stomach, changes so that some of its lining is replaced by a type of tissue similar to that normally found in the intestine. This process is called intestinal metaplasia.
Metaplasia from squamous to columnar type may also occur, as in Barrett esophagus, in which the esophageal squamous epithelium is replaced by intestinal-like columnar cells under the influence of refluxed gastric acid.he most common epithelial metaplasia is columnar to squamous (squamous metaplasia), as occurs in the respiratory tract in response to chronic irritation.
