,BIO 204 Final Exam Human Body in Health and Disease I Questions
And Answers 2026/2027 Jersey College
Q1. Which chamber receives deoxygenated blood returning from the
systemic circulation?
A) Right atrium
B) Left atrium
C) Right ventricle
D) Left ventricle
Correct Answer: A) Right atrium
Rationale: The superior and inferior venae cavae return systemic venous
blood to the right atrium.
Q2. Which chamber pumps blood into the pulmonary circulation?
A) Left atrium
B) Right ventricle
C) Right atrium
D) Left ventricle
Correct Answer: B) Right ventricle
Rationale: The right ventricle ejects deoxygenated blood through the
pulmonary trunk toward the lungs.
Q3. Oxygenated blood returning from the lungs enters the:
A) Right ventricle
B) Right atrium
C) Left atrium
D) Left ventricle
Correct Answer: C) Left atrium
Rationale: Pulmonary veins carry oxygenated blood from the lungs into the
left atrium.
Q4. Which chamber has the thickest myocardium?
A) Right atrium
B) Left atrium
C) Right ventricle
D) Left ventricle
, Correct Answer: D) Left ventricle
Rationale: The left ventricle must generate enough pressure to propel blood
throughout the systemic circulation.
Q5. Which valve lies between the right atrium and right ventricle?
A) Tricuspid valve
B) Mitral valve
C) Aortic valve
D) Pulmonary valve
Correct Answer: A) Tricuspid valve
Rationale: The tricuspid valve prevents backflow from the right ventricle
into the right atrium during ventricular contraction.
Q6. Which valve separates the left atrium from the left ventricle?
A) Pulmonary semilunar valve
B) Mitral valve
C) Tricuspid valve
D) Aortic semilunar valve
Correct Answer: B) Mitral valve
Rationale: The mitral or bicuspid valve controls blood flow from the left
atrium into the left ventricle.
Q7. What is the primary function of the chordae tendineae and
papillary muscles?
A) Generate the heartbeat
B) Supply oxygen to myocardium
C) Help prevent atrioventricular valve prolapse during ventricular contraction
D) Open the semilunar valves
Correct Answer: C) Help prevent atrioventricular valve prolapse during
ventricular contraction
Rationale: Chordae tendineae anchor atrioventricular valve cusps to
papillary muscles and help prevent valve inversion.
Q8. Which layer of the heart wall is composed primarily of cardiac
muscle?
