- Includes diagrams
- Contains 16 questions
Section 2: Physiology
- Includes 11 questions
- Covers cell physiology, heart function, urinary system, gastrointestinal tract, liver or pancreas, and nervous system physiology
Section 3: Pathophysiology
- Contains 15 questions

Section 4: Application Scenarios
- Contains 3 questions
- Assesses the ability to apply learned material and select the most appropriate answer in a scenario format
- Tests true understanding of the material, without providing additional information

Test 1 Questions

Question 1: Impairment of passive transport processes likely results in accumulation of substances outside the cell, rather than enhanced cellular energy production or facilitated movement against their concentration gradient. Reduced reliance on active transport mechanisms might occur but is not the primary consequence.
Question 2: The ST segment is LEAST likely to be directly affected during a heart attack among the listed ECG components (P, Q, R, T, and ST).
Question 3: The heart receives deoxygenated blood from the body primarily through the superior and inferior vena cava.

Additional Questions from Term One and Two Tests (Example)

Question: Which condition is characterized by restricted blood flow to tissues due to artery blockage?
- Answer: Schemia
