Cellular Adaptations: When exposed to physiological or pathological stress, cells undergo adaptive changes to preserve viability.Hypertrophy: Increase in cell size (e.g., left ventricular wall thickening from chronic hypertension).Hyperplasia: Increase in cell number.Metaplasia: Reversible replacement of one mature cell type by another (e.g., squamous metaplasia in the airway from chronic cigarette smoke).Dysplasia: Disordered, pre-cancerous cellular growth.Cell Death:Necrosis: Uncontrolled, accidental cell death resulting from ischemia or toxins, triggering a significant local inflammatory response.Apoptosis: Programmed, highly regulated cell death that occurs cleanly without provoking inflammation.2. Inflammation, Immunity, and HypersensitivityAcute vs. Chronic Inflammation: Acute inflammation is an immediate, short-term host defense characterized by vasudilation and neutrophil recruitment via complement activation. Chronic inflammation involves mononuclear cells (macrophages, lymphocytes) and can lead to tissue fibrosis and granuloma formation.Immunopathology: Breakdowns in immune tolerance result in autoimmune conditions, such as Type 1 Diabetes (autoimmune destruction of pancreatic $beta$-cells) or Systemic Lupus Erythematosus (SLE).3. Principles of Pharmacokinetics (ADME)Pharmacokinetics analyzes how the body processes a drug:Absorption: Movement into the bloodstream from the administration site.Distribution: Reversible transfer of drugs between circulation and body tissues, dependent on protein binding and perfusion.
