What is the location of the heart? - Correct answer- Cavity between
the lungs, 2/3 left of midsagittal
What is the size of the heart? - Correct answer- Roughly the size of
a fist
Pericardium - Correct answer- Outer membrane of the heart
Parietal pericardium - Correct answer- External (outer) layer of the
heart
Visceral pericardium (epicardium) - Correct answer- Part of the
heart wall
Functions of the pericardium and its 2 layers. - Correct answer-
Protection (physical barrier), anchors heart to other structures, and
provides lubrication to reduce friction.

2nd layer of the heart (middle layer that consists of twisted cardiac
muscle) - Correct answer- Myocardium (layer that actually
contracts)
3rd layer of the heart (inner layer made of epithelial tissue) -
Correct answer- Endocardium
What is the Atrium divided by? - Correct answer- Interatrial Septum
