Hypertrophy occurs when cells increase in size, typically in response to increased workload, such as in skeletal or cardiac muscles.
Coagulative necrosis results from ischemic injury, where protein denaturation preserves the basic cell structure.
Type III hypersensitivity involves immune complexes deposited in tissues, leading to inflammation, as seen in rheumatoid arthritis.
Neutrophils are the first responders in acute inflammation, migrating to the site of injury or infection.
Lipofuscin is an "age pigment" that accumulates in atrophic tissues due to oxidative stress and lipid peroxidation.
