2. Compare and contrast the various types of cellular adaptation.
3. Describe the various mechanisms of necrosis.
4. Mention some of the causes of each of the various types of
necrosis.
5. Compare and contrast necrosis and apoptosis.
6. Contrast metastatic and dystrophic calcification.

Answer 1

Studying cell injury helps us understand tissue response and repair. Cellular adaptation includes hypertrophy, hyperplasia, atrophy, and metaplasia. Mechanisms of necrosis include coagulative, liquefactive, caseous, and gangrenous. Metastatic calcification occurs in normal tissues due to hypercalcemia, while dystrophic calcification occurs in damaged tissues.

Step-by-step explanation:

Studying cell injury is important because it helps us understand how tissues respond to damage and guides strategies for repair. Different types of cellular adaptation include hypertrophy, hyperplasia, atrophy, and metaplasia. Mechanisms of necrosis include coagulative necrosis, liquefactive necrosis, caseous necrosis, and gangrenous necrosis. Causes of these types of necrosis can include ischemia, infections, toxins, and trauma. Necrosis is different from apoptosis in terms of the cause, mechanism, and outcome. Metastatic calcification occurs when calcium deposits in normal tissues due to hypercalcemia, while dystrophic calcification occurs in damaged or dead tissues.
