| Question | Answer |
| A fluid filled sac, double layer, that provides protection against infection and trauma | Pericardium |
| The outer layer of the pericardium | Fibrous pericardium |
| The inner layer of the pericardium which is made up of two layers | Serous pericardium |
| What two layers make up the serous pericardium? | Parietal and visceral layer |
| Lines the fibrous pericardium | Parietal layer |
| Adheres to the outside of the heart | Visceral layer |
| Aka the visceral layer, the outermost layer of the heart. | Epicardium |
| Center layer of the heart that consists of muscular tissue. | Myocardium |
| Striated muscle _____cause the heart to contract and relax. | Myofibrils |
| Consists of a thin layer of endothelium and underlying connective tissue. | Endocardium |
| The endocardium consists of? | Heart wall, valves, chordate tendinae, papillary muscles |
| Receives unoxygenated blood from the ventricles. | Right atrium |
| What is located to the right of the sternum and anterior in the chest cavity. | Right atrium |
| What 3 vessels empty into the RA? | SVC, IVC, coronary sinus |
| What is the normal RA pressure? | 0-8 mmhg |
| The most anterior chamber of the heart, and it lies directly beneath the sternum. | Right ventricle |
| This is where electrical conduction occurs, and this structure extends from the RV inferior free wall to the anterior septum and separates the inflow and outflow portions. | Moderator band |
| What is the normal RV pressure? | 16-30 mmhg peak systole, 0-8 mmhg end diastole |
| Aka infundibulum | Outflow tract |
| Contains pectin ate muscle that extend to the anterior LA wall. | Left atrial appendage |
| What are the left atrium pressures? | 0-12 mmhg |
| What are two distinct papillary muscles? | Anterior lateral, posteriormedial |
| What are the normal pressures for the LV? | 100-140 mmhg peak systole, 3-12 mmhg end diastole |
| ASD | Atrial septal defects |
| What are the atrioventricular valves? | Tricuspid, mitral |
| What are the three leaflets of the tricuspid valve? | Anterior, posterior, septal |
| What are the names of the leaflets of the mitral valves? | Anterior, posterior |
| What are two semilunar valves? | Pulmonic, aortic valve |
| What are the names of the three cusps of the pulmonic valves? | Anterior, right, left |
| What are the names of the valves of the aortic valve? | Right, left, non coronary |
| Aka in nominate | Bracheocephalic artery |
| What are the branches of the aortic arch? | Bracheocephalic, left common carotid, left subclavian |
