Expert Solution
Step 1: Explanation of concept

Necrosis:

  • Type of unregulated cell death.
  • Often caused by injury, infection, or pathological conditions.
  • Different forms include coagulative, liquefactive, caseous, and gangrenous necrosis.
  • Can lead to inflammation and tissue damage.

Inflammation:

Acute inflammation:

  • Rapid, short-term response to injury or infection.
  • Characterized by redness, swelling,heat, pain, and loss of function.
  • Involves white blood cell recruitment, especially neutrophils.
  • Aims to eliminate harmful agents and promote tissue repair.

Chronic inflammation:

  • Prolonged, low-level immune response.
  • Can result from unresolved acute inflammation or chronic exposure to irritants.
  • Involves lymphocytes and macrophages.
  • Associated with chronic diseases, such as rheumatoid arthritis and atherosclerosis.
