[{'content': 'Which of the following is an example of Labile tissue? \nSelect and explain. \nA. Transitional epithelium of the urinary tract, B. Parenchyma of most solid organs, C. Neurons, D. Skeletal muscles', 'role': 'user'}, {'content': 'Answer: A \nExplanation: The ability of tissues to repair themselves is determined, in\xa0part, by their intrinsic\xa0proliferative capacity.\xa0In some tissues called labile tissues, cells are constantly being lost and must be continually replaced by new cells\xa0that are derived from tissue stem cells and rapidly proliferating immature progenitors. These types of tissues include hematopoietic cells in the bone marrow and many surface epithelia, such as the basal layers of the squamous epithelia of the skin, oral cavity, vagina, and cervix; the cuboidal epithelia of the ducts draining exocrine organs (e.g., salivary glands,\xa0pancreas,\xa0 biliary\xa0tract);\xa0the\xa0columnar\xa0epithelium of the gastrointestinal tract, uterus, and\xa0fallopian\xa0tubes; and the transitional epithelium of the urinary tract. These tissues can readily\xa0regenerate\xa0after\xa0injury\xa0as\xa0long\xa0as\xa0the pool of stem cells is preserved.\nRobin’s Textbook of pathology 10th ed\xa0 Page 88', 'role': 'assistant'}]
