MODULE 1: BASIC SCIENCES
Cardiovascular System
• Q1. Which chamber of the heart pumps oxygenated blood into the systemic circulation?
• A) Right atrium
• B) Right ventricle
• C) Left atrium
, • D) Left ventricle
Rationale: The left ventricle pumps oxygenated blood through the aorta into the systemic
circulation. It has the thickest myocardial wall to generate the pressure needed for systemic
perfusion.
• Q2. What is the primary pacemaker of the heart?
• A) Atrioventricular (AV) node
• B) Bundle of His
• C) Sinoatrial (SA) node
• D) Purkinje fibers
Rationale: The sinoatrial (SA) node is the primary pacemaker, generating electrical impulses at
60–100 beats per minute. The AV node (40–60 bpm), Bundle of His, and Purkinje fibers (20–40
bpm) are secondary pacemakers.
• Q3. Which cardiac chamber receives oxygen-depleted blood from the systemic circulation?
• A) Right atrium
• B) Left atrium
• C) Right ventricle
• D) Left ventricle
Rationale: The right atrium receives deoxygenated blood from the superior and inferior vena
cava.
• Q4. According to Starling's law of the heart, an increase in end-diastolic volume will most
directly cause which change?
• A) Decreased heart rate
• B) Increased stroke volume
• C) Decreased contractility
• D) Increased afterload
Rationale: Greater ventricular filling stretches myocardial fibers, producing a stronger
contraction and larger stroke volume.
, • Q5. Which valve prevents backflow from the left ventricle to the left atrium?
• A) Pulmonary valve
• B) Tricuspid valve
• C) Aortic valve
• D) Mitral valve
Rationale: The mitral (bicuspid) valve closes during ventricular systole to prevent regurgitation
into the left atrium.
• Q6. The aortic valve is classified as which type of cardiac valve?
• A) Atrioventricular
• B) Semilunar
• C) Papillary
• D) Muscular
Rationale: The aortic and pulmonary valves are semilunar because of their half-moon shape.
• Q7. Cardiac output is calculated by multiplying stroke volume by heart rate. If a patient's
stroke volume is 70 mL and heart rate is 80 bpm, the cardiac output is:
• A) 5.6 L/min
• B) 3.5 L/min
• C) 7.0 L/min
• D) 4.2 L/min
Rationale: 70 mL × 80 = 5600 mL = 5.6 L/min.
• Q8. What is the normal sequence for the flow of blood through the heart and lungs?
• A) Right ventricle, right atrium, pulmonary artery, lungs, pulmonary vein, left atrium, left
ventricle, aorta
• B) Left atrium, left ventricle, pulmonary artery, lungs, pulmonary vein, right atrium, right
ventricle, aorta
