## UNIT 1 – CARDIAC ANATOMY & PHYSIOLOGY (20 Questions)
**Q1. Which chamber of the heart receives unoxygenated blood returning from the
body?**
A) Left atrium
B) Left ventricle
C) Right atrium
D) Right ventricle
**Answer: C**
*Rationale:* The right atrium receives deoxygenated blood from the superior and
inferior vena cava. Blood then passes through the tricuspid valve to the right
ventricle.
**Q2. Which valve controls blood flow between the left atrium and left
ventricle?**
A) Tricuspid valve
B) Mitral valve (bicuspid)
,2|Page
C) Aortic valve
D) Pulmonic valve
**Answer: B**
*Rationale:* The mitral (bicuspid) valve separates the left atrium from the left
ventricle. The tricuspid valve is on the right side.
**Q3. What is the muscular middle layer of the heart responsible for
contraction?**
A) Epicardium
B) Endocardium
C) Myocardium
D) Pericardium
**Answer: C**
*Rationale:* The myocardium is the muscular middle layer that contracts to pump
blood. The pericardium is the outer sac.
**Q4. The heart's blood supply is provided by which vessels?**
A) Pulmonary arteries
B) Coronary arteries
C) Carotid arteries
D) Femoral arteries
**Answer: B**
,3|Page
*Rationale:* The coronary arteries branch from the aorta and supply oxygenated
blood to the heart muscle (myocardium).
**Q5. Which vessels regulate regional blood flow to capillary beds?**
A) Arteries
B) Veins
C) Arterioles
D) Venules
**Answer: C**
*Rationale:* Arterioles are the primary resistance vessels that regulate blood flow
into capillary beds through vasoconstriction and vasodilation.
**Q6. What is the largest artery in the body?**
A) Pulmonary artery
B) Carotid artery
C) Aorta
D) Femoral artery
**Answer: C**
*Rationale:* The aorta is the largest artery, carrying oxygenated blood from the left
ventricle to the systemic circulation.
**Q7. Which veins bring deoxygenated blood back to the right atrium?**
A) Coronary veins
, 4|Page
B) Pulmonary veins
C) Venae cavae (superior and inferior)
D) Jugular veins
**Answer: C**
*Rationale:* The superior and inferior vena cava return deoxygenated systemic
blood to the right atrium.
**Q8. The pulmonary artery carries:**
A) Oxygenated blood away from the heart
B) Deoxygenated blood away from the heart (to the lungs)
C) Oxygenated blood toward the heart
D) Deoxygenated blood toward the heart
**Answer: B**
*Rationale:* The pulmonary artery is unique—it carries deoxygenated blood from
the right ventricle to the lungs for oxygenation.
**Q9. After blood has been oxygenated in the lungs, it returns to the heart by
entering the:**
A) Right atrium
B) Right ventricle
C) Left atrium
D) Left ventricle
