anatomy of the cardiovascular system Flashcards
what does the cardiovascular system
heart which is pump
blood vessels
arteries
capillaries where there is exchange of nutrients
veins collect and return blood to heart
lymphatics which drains excess extracellular fluid from tissues
what are the types of circulation
pulmonary circulation
systemic circulation
portal circulation
portal circulation
heart to lungs to heart
systemic circulation
heart to body to heart
location of the heart
superior mediastinum
inferior mediastinum
posterior mediastinum
anterior mediastinum
level of superior mediastinum
fourth thoracic vertebrae
location of inferior mediastinum
top region of the diaphragm
apex beat
5th intercostal space
parts of anterior mediastinum
sternum and costal cartilages 4 to 7
parts of posterior mediastinum
oesophagus and descending aorta and vertebrae T5-T8 in recumbent position
parts of lateral mediastinum
pleura and phrenic nerve
parts of inferior mediastinum
central tendon of the diaphragm
right border
right atrium
left border
left ventricle
posterior border
left atrium
superior border
: R auricle + L auricle + base of the great vessels
inferior border of the heart
RV + LV
anterior surface of the heart (sternocostal surface )
RA + RV + LV
inferior surface
RV +LV
POSTERIOR SURFACE
LA
right surface
right atrium
left surface of the heart
left ventricle
apex of the heart
5th left intercostal space in the midclavicular line
layers of the pericardium
fibrous
serous
serous pericardium
outer parietal layer
inner visceral layer that is the epicardium
blood supply of the heart
coronary artery
coronary arterial supply of the heart
Right coronary artery
left coronary artery
branches of right coronary artery
right marginal artery
posterior interventricular artery
branches of the left coronary artery
circumflex artery
anterior descending interventricular artery
point of anastomosis of the coronal arteries
anterior and posterior descending artery
supply by the right coronary artery
supply of the right atrium and the right ventricle
supply by the right marginal artery
supplies the right ventricle and apex
supply by left marginal artery
left ventricle
supply by anterior interventricular artery
right ventricle
left ventricle
interventricular sptum
venous drainage of the heart
great cardiac vein
middle cardiac vein
small cardiac vein
final drainage of the veins
coronary sinus which lies alongside the circumflex artery in the coronary sulcus or coronary groove
drainage of the of the coronary sinus
right atrium
extrinsic innervation of the heart
vagus nerve
sympathetic nerve
phrenic nerve
innervation of the fibrous pericardium and parietal layer of the serous pericardium
phrenic nerve
vagus nerves
innervate the myocardium and the visceral layer
sympathetic nerves origin
T1 -T4
sympathetic nerve innervation
myocardium and visceral layer of the serous pericardium
parts of right atrium
superior vena cava opening
inferior vena cava opening
coronary sinus opening
pectinate muscle
pectinate muscle
muscle on the right atrium
muscles of the right ventricle
trabeculae carneae
parts of a right ventricle
trabeculae carneae
papillary muscle
cordae tendineae
moderator band
parts of the left atrium
opening for the 4 pulmonary veins
pectinate muscle
