Overview
Welcome to the Module 5 Exam Review for BIOL251 – Human Anatomy & Physiology I w/
Lab (2025 edition). This comprehensive guide is designed to provide a high-yield, applied
review of the endocrine, cardiovascular, and lymphatic/immune systems, specifically
tailored for exams on LockDown Browser and Portage Learning.
Module 5 focuses on:
Endocrine System:
o Structure and function of major endocrine glands, including hypothalamus,
pituitary, thyroid, parathyroid, adrenal, pancreas, pineal, thymus, and gonads
o Hormone classes, target organs, feedback loops, and regulatory mechanisms
o Applied lab identification of glands and hormone-related physiological scenarios
Cardiovascular System:
o Heart anatomy, cardiac conduction system, coronary circulation, and cardiac
cycle
o Blood vessels: arteries, veins, capillaries, and systemic/pulmonary pathways
o Cardiac output, blood pressure, stroke volume, and ECG interpretation
o High-yield lab scenarios for understanding cardiac and vascular physiology
Lymphatic & Immune System:
o Structure and function of lymph nodes, spleen, thymus, tonsils, and lymphatic
vessels
o Innate and adaptive immunity, immune cells, antibodies, and antigen presentation
o Applied clinical scenarios including vaccination, infection, and immune responses
Features of this Review Guide:
90 carefully curated multiple-choice questions, divided into three sections:
o Section 1: Endocrine System (Q1–30)
o Section 2: Cardiovascular System (Q31–60)
o Section 3: Lymphatic & Immune System (Q61–90)
