Beginner Small Cardiac Vein Quiz

Q1. The small cardiac vein is part of which circulatory system?

• Hepatic portal circulation
• Cerebral arterial circulation
• Pulmonary arterial circulation
• Cardiac venous circulation

Q2. The small cardiac vein primarily drains which side of the heart?

• Left atrium exclusively
• Right side
• Left side exclusively
• Interatrial septum exclusively

Q3. Which artery is commonly associated with the small cardiac vein near the right margin of the heart?

• Right marginal artery
• Circumflex artery
• Anterior interventricular artery
• Left marginal artery

Q4. After reaching the coronary sulcus, which artery does the small cardiac vein commonly accompany?

• Anterior interventricular artery
• Left coronary artery
• Right coronary artery
• Pulmonary artery

Q5. In which groove does the small cardiac vein travel as it passes posteriorly?

• Coronary sulcus
• Posterior interventricular sulcus
• Terminal sulcus
• Anterior interventricular sulcus

Q6. The small cardiac vein usually drains into which major venous structure?

• Left atrium
• Pulmonary vein
• Coronary sinus
• Superior vena cava

Q7. The coronary sinus ultimately empties blood from the small cardiac vein into which chamber?

• Right ventricle
• Right atrium
• Left atrium
• Left ventricle

Q8. What type of blood is carried by the small cardiac vein?

• Oxygenated blood from the aorta
• Portal blood from the intestine
• Oxygenated blood from the lungs
• Deoxygenated blood from the myocardium

Q9. Which cardiac vein travels in the posterior interventricular sulcus rather than the right coronary sulcus?

• Oblique vein of the left atrium
• Anterior cardiac vein
• Small cardiac vein
• Middle cardiac vein

Q10. Which statement best describes the small cardiac vein?

• It carries oxygenated blood from the lungs
• It drains the left ventricle directly into the left atrium
• It supplies arterial blood to the right ventricle
• It drains portions of the right heart and usually terminates in the coronary sinus
