Answer |
| location of heart (8) facts to remember |
posterior to sternum; medial to lungs; anterior to veterbal column base; lies beneath 2nd ribapex at 5th intercostallies upon diaphragmbase: medialapex: lateral |
| the wall of the heart of composed of these 3 layers |
epicardium; myocardium; endocardium |
| the epicardium is also called the _________ |
visceral periocardium: which is the outter layer of the heart and the inner layer of the pericardium |
| the visceral pericardium or epicardium depending on nomenclature function is to |
form a protective outer covering; secretes serous fluid to protect from friction with outside organs and tissue |
| the myocardium: |
is cardiac muscle tissue seperated by connective tissue and blood and lymph capillaries and nerve fibers |
| the function of the mycardium is to |
contracts to pump blood from the heart chambers |
| the endocardium is a membrane made of |
epithelium and underlying connective tissue, including blood vessels and specialized muscle fibers |
| the function of the endocardium is |
to form a protective inner lining of the chambers and valves |
| the periocardial cavity is what the pericardium sits in, it is also a common site for |
infections |
| the pericardium (or pericardio sac) |
surrounds the heart and is made of connective tissue |
| the pericardium is made to 2 layers and each layer is respectily made of a different tissue each, which are |
parietal pericardium; fibrous pericardium-- |
| fibrous pericardium is... |
is a tough, protective sac of dense connective tissue: most superficial layer |
| parietal pericardium... |
surrounds the epicardium, and connects at the base of the heart the visceral (epicardium) pericardium. |
| pericardial cavity is... |
In between the parietal and visceral pericardial layers there is a potential space called the pericardial cavity. It is lubricated by a film of serous fluid. |
| visceral pericaridium is... |
epicardium |
| serous pericardium |
The serous pericardium consists of two layers: a parietal pericardium and a visceral pericardium |
