Pre-Lab – The Heart
Heart anatomy
1. Label the following features of the heart on Figure 4.1 below.
1. Superior vena cava 9. Chordae tendineae
2. Aorta 10. Apex
3. Right atrium 11. Right ventricle
4. Left atrium 12. Left ventricle
5. Right atrioventricular valve 13. Pulmonary arteries
6. Left atrioventricular valve 14. Pulmonary veins
7. Rt Coronary artery 15. Pulmonary trunk
8. Interventricular septum 16. Inferior vena cava

2. On Figure 4.1, use arrows to show the direction of blood flow through the heart. See numbers
on diagram 4.1
The heart has its own circulation that supplies and drains the heart wall with blood, the coronary
circulation. The major vessels of coronary circulation lie in grooves (sulci) on the surface of the heart.
In a fully intact heart the grooves are covered in adipose tissue – once this is removed the individual
vessels can be seen. The heart beats day in day out, and cardiac muscle cells require a lot of oxygen
and ATP to function – therefore coronary circulation is vital for our survival. A person suffering from
coronary heart disease may require a coronary stent - a tube- shaped device placed in a coronary
artery - to keep the coronary artery open and thus the heart functioning as required.
