The sac that surrounds and protects the heart is called the: 1. pericardium. 2. myocardium. 3. endocardium. 4. pleural space. - Answer ANS: 1 The pericardium is a tough fibrous double-walled sac that surrounds and protects the heart. It has two layers that contain a few milliliters of serous pericardial fluid. The direction of blood flow through the heart is best described by which of the following? 1. Vena cava—right atrium—right ventricle—lungs—pulmonary artery—left ...

Describe the pericardial friction rub and state the expected assessment findings Correct Answer--High pitched, muffled, grating, and leathery sound heard with each heartbeat. -Caused by the friction of the visceral and parietal layers of the pericardium. -May be indicative of pericardial sac inflammation (pericarditis); fluid may accumulate between the pericardial layers of the heard Trace a drop of blood through the body Correct Answer-Blood enters through the superior vena cava/ inferior...
