Cellular Injury and Death

Cellular injury and death form the core of pathological processes, explaining how cells respond to harmful stimuli such as hypoxia, toxins, infections, and physical trauma. This tertiary-level topic covers reversible and irreversible injury, necrosis, apoptosis, and the morphological patterns of tissue necrosis—coagulative, liquefactive, caseous, gangrenous, fat, and fibrinoid. For Zambian college and university students in health sciences, laboratory programs, or medical degrees, this knowledge is essential for diagnosing diseases, understanding tissue damage, and interpreting autopsy findings. The material is aligned with diploma and degree syllabi, emphasizing clinical relevance and examination readiness. Mastery of cell injury mechanisms supports success in professional assessments and enhances diagnostic competence in real-world healthcare settings.
