THE HUMAN HEART LAB
PART A: ANATOMY OF THE HUMAN HEART
Obtain a model of the human heart. Using your PowerPoint and Visible Body Atlas for
reference, identify each of the BOLDED structures and place a labeled flag on the
structure. Submit pictures of your labeled models with the lab. (10 points)
Once you have labeled each structure on the models, label them on the pictures in this
lab. (1 point each)
As you identify them, answer the questions that follow them. (1 point each)
VESSELS
Superior Vena Cava
1. Into what chamber of the heart does this vessel drain?
Inferior Vena Cava
2. Into what chamber of the heart does this vessel drain?
Pulmonary Trunk
3. From what chamber does this vessel leave?
Pulmonary Arteries (L&R)
4. Where are these arteries leading?
5. What type of blood are they carrying?
Pulmonary Veins (L&R)
6. From where are these veins coming?
7. What type of blood are they carrying?
Coronary Arteries
8. Specifically, what structures are these vessels supplying?
9. What type of blood are they carrying?
Coronary Veins
10. Specifically, from where has the blood in these veins come?
11. To what large vessel along the *base* of the heart are they leading?
, Coronary Sinus
12. Into which chamber does the blood in this vessel drain?
Aorta (3 parts: Ascending, Arch, and Descending)
13. What do you observe about the diameter of the aorta, compared with other vessels?
CHAMBERS
Right Atrium
14. From what three vessels does this chamber receive blood?
a)
b)
c)
Right Ventricle
15. What structure found in the right ventricle helps distribute the electrical impulse to
the myocardium of the right ventricle and keep the right ventricle from over-extending?
Left Atrium
16. From what vessel does the left atrium receive its blood?
Left Ventricle
17. What do you observe about the myocardium of the left ventricle, when comparing it
to the other three chambers?
VALVES
Tricuspid (Right AV) Valve
18. What two chambers does this valve separate?
Pulmonary Semilunar Valve
19. To what vessel is this valve leading?
Bicuspid (Left AV) Valve
20. What is the clinical name for this valve?
21. What two chambers does it separate?
