Exam Study Guide
Explain the location of the Heart in the body - Answer located in the mediastinum, sitting
on the left side more, the apex points down towards the Left hip.
What is the structure of the pericardium? - Answer Fibrous Pericardium (outermost
layer made of tough dense CT)
Serous pericardium (2 Layers)
Parietal is the outer layer
Visceral is the inner layer
Serous fluid is between these two layers
What is the function of the pericardium - Answer Anchors heart to diaphragm
does not stretch to prevent heart from overfilling
What is the function of serous fluid in the pericardium? - Answer Lubricates and allows
for smooth, friction-less movement of the heart.
What are the three layers of the heart wall (deep to superficial) - Answer Endocardium
(endothelium)
Myocardium (cardiac muscle)
Epicardium (is the visceral layer of serous pericardium)
What is the systemic circulation? - Answer carries oxygenated blood away from the
heart to the body, and returns deoxygenated blood back to the heart
What is the pulmonary circulation? - Answer circulation between heart and lungs
What is the flow of blood through the heart? - Answer Superior and inferior vena cava,
right atrium, tricuspid valve, right ventricle, pulmonary semilunar valve, pulmonary
artery, lungs (picks up oxygen), pulmonary veins, left atrium, mitral valve (bicuspid), left
ventricle, aortic semilunar valve, aorta, to the body
What is coronary circulation? - Answer Blood vessels that deliver blood to, and take
blood from, the heart tissue itself.
What are the key vessels of coronary circulation? - Answer Coronary Arteries
