Pericardium:!
-Outermost layer is the superficial fibrous pericardium, helps
to protect the heart and the cavity. Also anchors it in place!
-Prevents overfilling of the heart with blood, gives a limit of
how much blood can get into the heart – important function.
Without it there would be stretching of the tissue and then
dysfunction!
-Serous fluid and visceral pericardium allow for the heart to
work in a relatively friction free environment!
-Beneath that is a deep two-layer serious pericardium:
parietal and visceral layers, visceral layer is directly on top of
the heart muscle -Serous fluid separates them
Myocardium – beneath the pericardium!
-Muscle layer forming the bulk of the mass of the heart,
comprised of cardiac muscle cells, striated!
-Provides support for big vessels and valves!
-Branching muscle cells arranged in bundles!
-Specialized structures within the cardiomyocytes allow for
the conduction of action potentials
Then Endocardium – endothelial layer of the inner
myocardial surface; continuous vessels leaving and entering
the heart

Vessels returning blood to the heart include the superior and
inferior venae cavae; left and right pulmonary veins.
Arteries take blood away from the heart such as, pulmonary
trunk, which splits into right and left pulmonary arteries;
ascending aorta (three branches taking blood to arms and
head)
Arteries – right and left coronary arteries (in atrioventricular
groove), marginal, circumflex and anterior interventricular
arteries.
Veins – Small Vardiac, anterior cardiac and great cardiac
veins

Fossa Ovalis – developmental remnant that developed as a
fetus when the atriums are joined.!
Left atrium and left ventricle separated by a bicuspid valve,
right atrium and right ventricle separated by a tricuspid
valve.
Interventricular septum separates ventricles.
Atria of the Heart – receiving chamber of the heart, take the
blood in and take it to the ventricles.!
-Both left and right atriums have pectinate muscles along the
walls -Both have a protruding auricle

Document Summary

Outermost layer is the super cial brous pericardium, helps to protect the heart and the cavity. Prevents over lling of the heart with blood, gives a limit of how much blood can get into the heart important function. Without it there would be stretching of the tissue and then dysfunction. Serous uid and visceral pericardium allow for the heart to work in a relatively friction free environment. Beneath that is a deep two-layer serious pericardium: parietal and visceral layers, visceral layer is directly on top of the heart muscle -serous uid separates them. Muscle layer forming the bulk of the mass of the heart, comprised of cardiac muscle cells, striated. Specialized structures within the cardiomyocytes allow for the conduction of action potentials. Then endocardium endothelial layer of the inner myocardial surface; continuous vessels leaving and entering the heart. Vessels returning blood to the heart include the superior and inferior venae cavae; left and right pulmonary veins.
