Lab 03: Heart Anatomy (10 points)
Lab Report 3: Exercise 30 (all) + Review Sheet 30 (Questions 1-16) in Marieb & Mitchell +
Supplemental Sheets 1-3.
Pierce College Student Outcomes:
Lab Outcome 4: Identify superficial and deep structures of the heart, including the conduction
system, on various heart models, diagrams, and by sheep heart dissection.
Lab Outcome 5: Describe and demonstrate patterns of blood circulation throughout the human
body, including systemic, pulmonary, cerebral, coronary, hepatic portal, and fetal circulations on
models, diagrams and dissected cat specimens. (in part)
Successfully completing and understanding the following Study Guide Objectives should prepare
you to be tested over this material, demonstrating your mastery of the above student outcome(s).
1. On models, cadaver preparations, photographs or diagrams of the human heart, identify the
following structures:
superior vena cava
bicuspid valve (mitral valve, L
inferior vena cava
atrioventricular valve)
R atrium
L ventricle
fossa ovalis
interventricular septum
tricuspid valve (R atrioventricular valve)
aortic semilunar valve (aortic valve)
chordae tendenae
ascending aorta
papillary muscles
aortic arch
trabeculae carnae
brachiocephalic artery
pulmonary semilunar valve (pulmonary valv) L common carotid artery
pulmonary trunk
L subclavian artery
R pulmonary artery
endocardium
L pulmonary artery
myocardium
R pulmonary veins
pericardium (visceral pericardium)
L pulmonary veins
apex of the heart
L atrium
2. Be able to write out the path a blood cell would take through the heart in pulmonary and
systemic circulation, beginning with the superior OR inferior vena cava and ending with the
ascending aorta, identifying and naming all of the structures in Objective 1 above.
Pulmonary and Systematic Circulation Tracing:
From upper body to superior vena cava OR from the lower body to the inferior vena cava>R
atrium>through tricuspid (R atrioventricular) valve>R ventricle>through pulmonary semilunar
valve>pulmonary trunk>R or L pulmonary artery into lungs>pulmonary
arterioles>capillaries>pulmonary venules>R or L pulmonary veins>L atrium>through bicuspid
(mitral, L atrioventricular) valve>L ventricle>through aortic semilunar valve>ascending aorta>to
the body.

3. On models, cadaver preparations, photographs or diagrams of the human heart, identify the
following structures:
ascending aorta
posterior interventricular artery
aortic arch
anterior interventricular artery
R and L auricle
small cardiac vein
superior vena cava
middle cardiac vein
R and L ventricle
great cardiac vein
R and L coronary artery
coronary sinus
marginal artery
R atrium
circumflex artery
4.
Be able to write out paths a blood cell would take through the heart in coronary circulation,
beginning with the ascending aorta and ending with the R atrium, and naming all of the
major coronary arteries and veins (listed in Objective 2).
Sample Coronary Circulation Tracings:
1) Ascending aorta>R coronary artery>marginal artery>arterioles>capillaries of R
ventricle>venules>small cardiac vein>coronary sinus>R atrium.
2) Ascending aorta>R coronary artery>posterior interventricular artery>arterioles>capillaries of
L ventricle>venules>middle cardiac vein>coronary sinus>R atrium.
3) Ascending aorta>L coronary artery>circumflex artery>arterioles>capillaries of L
atrium>venules>great cardiac vein>coronary sinus>R atrium.
4) Ascending aorta>L coronary artery>anterior interventricular
artery>arterioles>capillaries>venules>middle cardiac vein>coronary sinus>R atrium.
5.
From photographs, sketches or under the microscope, identify cardiac muscle and identify
intercalated discs and nuclei.
6.
Identify the following external structures on a sheep heart:
base of the heart
R and L ventricles
apex of the heart
fat
aorta
pulmonary artery
ligamentum arteriosum
opening of superior vena cava
R and L auricles
opening of inferior vena cava
R and L atria
pulmonary veins
7. Identify the following internal structures in a dissected sheep heart:
R and L atria
trabeculae carneae
entrance of superior vena cava
R and L ventricle
entrance of inferior vena cava
tricuspid (R atrioventricular) valve
fossa ovalis
bicuspid (mitral, L atrioventricular) valve
chordae tendineae
pulmonary semilunar valve
papillary muscle
aortic semilunar valve
pectinate muscles
