,CORE DOMAINS
Homeostasis and feedback mechanisms*
Cells, tissues, and membranes*
Endocrine system*
Cardiovascular system and blood*
Respiratory system*
Digestive system*
Urinary system*
Lymphatic and immune function*
, Reproductive anatomy and physiology*
Professional practice, ethics, and safety*
INTRODUCTION
This exam review assesses core anatomy and physiology knowledge with emphasis on how body systems
maintain homeostasis and respond to change. It measures understanding of foundational structures,
physiological processes, and clinically relevant relationships across major organ systems. The questions
combine multiple-choice knowledge checks with scenario-based application to reflect real exam expectations.
Strong performance requires accurate recall, sound reasoning, and the ability to apply theory to patient-
centered decision-making, professional standards, and real-world clinical situations. The test format is
designed to strengthen both content mastery and practical judgment for academic and professional success.
