Pathology MCQs
Pathology MCQs assess knowledge of disease mechanisms, histopathology, and systemic conditions. Covering organs like liver, lungs, heart, and kidneys, they help MDCAT, USMLE, NTS, and FCPS aspirants strengthen concepts and clinical understanding.
Q: Increased capillary permeability during inflammation leads to
A) Hemorrhage
B) Vasoconstriction

Q: The process of opsonization enhances
A) Cell division
B) Inflammation resolution
C) Phagocytosis
D) Blood clotting
