Notes

1

parietal pleura (location)

2

visceral pleura (location)

3

pleural cavity (location)

A

fibrous pericardium & parietal pericardium (location)

B

visceral pericardium or epicardium (location)

C

pericardial cavity (location)

7

interventricular septum

8

papillary muscle

9

right ventricle

Personal note: One way to memorize this is specifically the right ventricle is that it’s closest the sternum, meaning it will be compressed first when doing CPR.

10

left ventricle

11

right atrium

12

tricuspid valve

Notes

The fibrous pericardium is the most superficial (outermost) layer of the pericardium; The parietal pericardium touches the inside of the fibrous pericardium

Personal note, not in slideshow: It’s hard to tell which side is left or right, but knowing that the heart sticks out on the left(?) side of the chest, you can know which side it is.
