Review of Section 2 : Self-test

This page is best viewed with Internet Explorer. Position your mouse over the answer button and the answer to the question will appear.

 1. Which organ is formed first in the human embryo? The heart and blood vessels are formed before any other organ.

 2. The fetal heart is a miniature version of the adult heart by what age in development? By the eight week of fetal development, the heart possesses four chambers.

 3. What changes occur shortly after birth in the human heart? The foramen ovale should be closed completely. The ductus arteriosus shrinks, closing in about a week.

 4. What disease processes interfere with heart development? Rubella and rubeola (measles) viruses may interfere with heart development.

 5. What condition does Dextrocardia and Dextroversion describe? Dextrocardia and Dextroversion describe a congenital condition whereby the heart is positioned in the right half of the torso.

 6. The coronaries supply blood to the muscle tissue and what other system? The coronary arteries supply blood, oxygen, and nutrients to the heart muscle and the conduction system.

 7. What percentage of blood flows into resting myocardium ?  Resting myocardium receives less than 5% of the cardiac output.

 8. Coronary disease mainly affects the function of which chamber?  Because the muscle mass of the left ventricle exceeds that of the right ventricle, the coronary arteries need to supply more blood and oxygen to the left ventricle than to the right.

 9. Where do the right and left coronary arteries originate?  They originate at the base of the aorta, commonly known as the aortic root.

10. Name the branches of the LEFT coronary artery.  The Left Anterior Descending and the Left Circumflex Arteries.

11. Name the branches of the RIGHT coronary artery.  The Marginal Branch and the Posterior Descending Artery.

12. Into what vessel does waste-laden blood from the myocardium drain after the nutrient exchange has occurred?  The Coronary Sinus.

13. Arterial blood flow is dependent on what two factors?  Arterial flow in the coronary arteries is dependent on the blood pressure and vascular resistance.

14. What happens to normal coronaries when an increased workload is put on the heart? In the healthy heart, the coronary arteries can meet increased demand by dilating and increasing coronary blood flow, delivering more oxygen.

15. What happens to anastomoses in the myocardium when the blood supply becomes compromised? When a large area of the heart is deprived of blood, these anastomoses enlarge and then provide a collateral blood supply to the affected muscle.
