Block 2 - Middle Mediastinum / Heart Flashcards
two layers of pericardium
parietal, visceral
between pericardial layers is the blank
pericardial space
accumulation of fluid from pericarditis is called a cardiac blank
tamponade
blank is needed to remove tamponade
pericardiocentesis
two pericardial sinuses
transverse, oblique
sinus that connects the right and left sides of the pericardial cavity
transverse
sinus that is an inverted u shaped sinus dorsal to left atrium between pulmonary veins and superior vena cava
oblique
fluid in pericardial cavity will flow to this sinus
oblique
id oblique sinus
ok
this separates the atria from ventricles
atrioventricular groove
septum between ventricles
interventricular septum
apex of heart is located at blank intercostal space in the midclavicular line
5th
most anterior chamber of the heart
right ventricle
three branches of RCA
posterior interventricular artery, marginal, nodal
LCA branches
circumflex, anterior interventricular artery
supplies right atrium and sa node
nodal branch
supplies anterior wall of right ventricle
right marginal
posterior wall of right ventricle, posterior part of septum
posterior interventricular
supplies anterior left ventricle, most of iv septum, apex
anterior interventricular
supplies lateral wall of left ventricle
left marginal
supplies posterior wall of left atrium and left ventricle
circumflex
most hearts are blank dominant
right
heart dominance depends on the coronary artery that supplies blank
posterior interventricular artery
drains blood from both ventricles and the left atrium and lies in the anterior interventricular sulcus
great cardiac vein
veins of the av groove that drain directly into right atrium not the coronary sinus like most veins
anterior cardiac veins
coronary sinus empties into blank
right atrium
largest heart valve
tricuspid valve
tiny strands of ct that are attached to papillary muscles
chordae tendineae
aortic valve is heard in the blank
right second intercostal space
pulmonic valvie is heard in the blank
left second intercostal space
mitral valve is heard in the blank
left fifth intercostal space at midclavicular line
ventricular filling
diastole
ventricular emptying
systole
tricuspid valve is heard blank
left of xiphosternal junction
tricuspid and mitral valves close during
systole
bundle of his comes from the blank
av node
bundle of his has blank branches
right/left bundle branches
right bundle branch goes into the blank
moderator band
cardiac plexus is made up of blank
sympathetic/parasympathetic
this encloses the heart, proximal great vessels, and terminal segment of inferior vena cava
pericardium
