Answer 1

- ® General cause of cell atrophy: Ans: (c) ischemia Explanation: causes of cell atrophy include supposcia ischemia, chemical agents & drugs, microbial agents, immunogenic agents, aging, lakogenic factors, diopathis disease. Rernervation, endocrine stimulation we under general conse of cell atrophy ③ Decrease in work demands most cells will Ams(b) decease in size % organelles Explanation: ere is increase in world demand, there will be increase in oxygen consumption. increased mitochondrial growth. when there is decrease in work demands, there will be decrease in size of organelles. Decreased programmed cellular death interno means growth of a tumor. ③ Diabetic foot. Ans: Most gangrene (d) Explockan In moist gangrene (or wet gangrene there wont be line of demaxcation, spreads rapidly of has foul odour. In wet dry gangrene there will be line of demarcation. Gas gangrene - affected area ematous, painful, crepitant due to Gangrene of internal organs is called gangeene. internal accumulation of gas bubbles within the kinos. 4 study of abnormal functioning of Ans: las pathology Explanahon diseased organ.

Pathology is the study of nature of an infection or disease, which produce stouchnal changes & functional changes. Pathophysiology means physiological proces which is not functioning properly or dis ordered that produce disease or Injury. Ehology means factors or causes that are responsible for the occuence of disease or Condition. ③ Apophosis differs from ne crosis: Ans: (a) is highly selective in eliminating injured or Explanations aged cells. In necrosis, there is uncontrolled release of product of cell death, it initiates an inflammatory response, & it is highly unregulated by enzymatic digestion of cell components, where as appphosh I just the opposite
