Correct Answers & Detailed Rationales
(Cardiovascular • Respiratory • Digestive • Urinary • Reproductive •
Endocrine Systems)
1. Which chamber of the heart has the thickest wall?
A. Right atrium
B. Left atrium
C. Right ventricle
D. Left ventricle
Correct Answer: D. Left ventricle
Rationale:👀*** It pumps blood to the entire body and requires the most force.
2. The mitral valve is located between the:
A. Right atrium and right ventricle
B. Left atrium and left ventricle
C. Left ventricle and aorta
D. Right ventricle and pulmonary trunk
Correct Answer: B. Left atrium and left ventricle
Rationale:👀*** The mitral (bicuspid) valve prevents backflow into the left
atrium.
3. Which blood vessel carries oxygenated blood away from the heart?
A. Vein
B. Capillary
,C. Artery
D. Venule
Correct Answer: C. Artery
Rationale:👀*** Arteries carry blood away from the heart (usually oxygenated).
4. The pulmonary circulation carries blood between the:
A. Heart and body tissues
B. Heart and kidneys
C. Heart and lungs
D. Lungs and brain
Correct Answer: C. Heart and lungs
Rationale:👀*** Pulmonary circulation allows gas exchange in the lungs.
5. Which part of an ECG represents ventricular depolarization?
A. P wave
B. QRS complex
C. T wave
D. PR interval
Correct Answer: B. QRS complex
Rationale:👀*** Ventricular depolarization triggers ventricular contraction.
6. Which blood pressure reading represents systolic pressure?
A. Bottom number
B. Mean arterial pressure
,C. Pressure during ventricular relaxation
D. Pressure during ventricular contraction
Correct Answer: D. Pressure during ventricular contraction
Rationale:👀*** Systolic pressure occurs when ventricles contract.
7. Which hormone increases heart rate and blood pressure during stress?
A. Insulin
B. Aldosterone
C. Epinephrine
D. ADH
Correct Answer: C. Epinephrine
Rationale:👀*** Epinephrine activates the sympathetic nervous system.
8. Which plasma protein is most abundant?
A. Fibrinogen
B. Globulin
C. Albumin
D. Hemoglobin
Correct Answer: C. Albumin
Rationale:👀*** Albumin maintains osmotic pressure and transports
substances.
9. Hemoglobin’s primary function is to:
A. Transport nutrients
B. Fight infection
, C. Carry oxygen
D. Regulate pH
Correct Answer: C. Carry oxygen
Rationale:👀*** Hemoglobin binds oxygen in red blood cells.
10. Which white blood cell is most abundant?
A. Lymphocyte
B. Monocyte
C. Eosinophil
D. Neutrophil
Correct Answer: D. Neutrophil
Rationale:👀*** Neutrophils are the body’s first responders to infection.
11. Which vitamin is required for clotting factor synthesis?
A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin K
Correct Answer: D. Vitamin K
Rationale:👀*** Vitamin K is necessary for production of clotting factors.
12. The process of forming blood cells is called:
A. Hemolysis
B. Hematopoiesis
