Lungs/heart Flashcards
Label arteries 1-7
ausculation point for murmur of patent ductus arteriosus
just lateral to pulmonary semilunar valve sound point
(just lateral to left of sternum over 2nd intercostal space)
What empties into coronary sinus and what is each vein paired with?
- great cardiac vein (w/ anterior interventricular artery)
- middle cardiac vein (w/ posterior interventricular artery)
- small cardiac vein (w/ right marginal artery)
where is opening of coronary sinus
right atrium
right atrium receives blood from what cardiac veins?
anterior cardiac veins
bronchial arteries carry what kind of blood where?
bronchial arteries carry oxygenated blood from thoracic aorta to supporting tissues of lungs and visceral pleura
3 layers of pericardium
- inner serous layer
- visceral
- parietal
- outer fibrous layer
where is the oblique pericardial sinus?
cul-de-sac in the pericardial cavity posterior to the heart
chordae tendinae (where and function)
in right ventricle
stabilize valve cusps
papillary muscles (where and function)
in right ventricle
contract to tighten chordae tendinae
Ausculation area for mitral valve sound
apex of the heart at the 5th intercostal space below left nipple
At what level does the trachea bifurcate/ what does it bifurcate into?
bifuracates at level of transverse thoracic plane into
2 main (primary) bronchi
pulmonary trunk divides into?
right and left pulmonary arteries
where is the transverse pericardial sinus?
posterior to the intrapericardial parts of the pulmonary trunk and ascending aorta and anterior to the SVC and superior to the atria of the heart
name the 4 valves
where are pectinate muscles found?
wall of right atrium
where is fossa ovales
in right atrium towards left atrium
name the 4 chambers
moderator band (where and function)
part of conduction system in right ventricle
Label the following
A) arch of aorta
B) SVC
C) right atrium
D) auricle of right atrium
E) right ventricle
F) left ventricle
G) apex of heart
H) auricle of left atrium
crista terminalis
between smooth and muscular portions of atrium
pulmonary arteries divide into?
lobar and segmental arteries within the lungs
carina
midline cartilaginous ridge separating the lumens of the two primary bronchi (@last tracheal ring)
Ausculation area for tricuspid valve sound
midline and to the left side of sternum at 5th intercostal space
describe difference between right and left main bronchus
right is wider, shorter and runs more vertically
left runs inferior to arch of aorta and anterior to esophagus and thoracic aorta
pulmonary embolism
- occurs when blood clot, fat globule, air bubble travels to lungs (usually originates from leg vein)
- then may block pulmonary artery
- causes acute respiratory distress becuase of decrease in blood oxygenation
CABF
coronary artery bypass graft
vein taken from leg and used to bypass narrowed coronary arteries (used as collaterols)
Ausculation area for aortic semilunar valve sound
right of sternum over 2nd intercostal space
also in the neck over carotid artery
function of auricle
can increase capacity of atrium
Ausculation area for pulmonary semilunar valve sound
left of sternum over 2nd intercostal space
describe general flow of coronary circulation
- aorta
- right coronary artery
- sinoatrial nodal artery
- right marginal artery
- posterior interventricular artery
- left coronary artery
- anterior interventricular (LAD)
- circumflex artery
- right coronary artery
trabeculae carnae (where and function)
muscular ridges in right ventricle
