NU 545 Ch2 EXAM QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS GRADED A++ LATEST UPDATE Metaplasia the reversible replacement of one mature cell by another ex: replacement of normal columnar ciliated epithelial cells of the bronchial (airway) lining by stratified squamous epithelial cells The loss of ATP leads to Swell because of the influx of sodium chloride (NaCl). leads to an intracellular accumulation of sodium and calcium and diffusion of potassium out of the cell. Sodium and water can then freely enter the cell, and cellular swelling results. Hormonal hyperplasia occurs chiefly in estrogen-dependent organs, such as the uterus and breast Free radicals play a major role in the initiation and progression of which diseases? Cardiovascular diseases such as hypertension and ischemic heart disease Free radicals cause cell damage by Giving up an electron, which causes injury to the chemical bonds of the cell membrane consequence of plasma membrane damage to the mitochondria? Influx of calcium ions halts ATP production. What is a consequence of leakage of lysosomal enzymes during chemical injury? Enzymatic digestion of the nucleus and nucleolus occurs, halting DNA synthesis. Lead causes damage within the cell by interfering with the action of Calcium apoptosis process of programmed cell death Lead poisoning Interfering with the function of neurotransmitters Carbon monoxide causes tissue damage by: Binding to hemoglobin so that it cannot carry oxygen Acute alcoholism mainly affects which body system Acute alcoholism mainly affects the central nervous system but may induce reversible hepatic and gastric changes. Other systems may evidentially be affected by chronic alcoholism. During cell injury caused by hypoxia, an increase in the osmotic pressure occurs within the cell because: Sodium chloride enters the cell subdural hematoma and epidural hematoma A subdural hematoma is often the result of shaken baby syndrome, whereas an epidural hematoma rapidly forms as a result of a skull fracture.
