left brachicephalic
|
from in root of neck from internal jugular vein and subclavian vein
posterior to posterior end of clavicle has to get past the midline |
|
right brachiocephalic vein
|
from in root of neck from internal jugular vein and subclavian vein
posterior to posterior end of clavicle |
|
superior vena cavae
|
formed by two brachiocephalic veins
posterior to costal cartilage of first rib...goe sto superior aspect of right atrium. enters posterior to costal cartilage of right 3rd rib |
|
inferior vena cavae
|
travels through caval foramen
|
|
azygous vein
|
unites with posterior side of SVC
|
|
thoracic aorta
|
divided into:
ascedning aorta aortic arch descending thoracic aorta |
|
aortic arch path
|
ascends and moves to the right. the arch then moves posteriorly and to the left
crosses the sternal angle - marks where arch turns to thoracic aorta limited to superior mediastinum |
|
branches of arch of aorta
|
ascending aorta
L common carotid artery L subclavian artery |
|
branches of ascending arch
|
L and R coronary arteries
|
|
brachiochephalic
|
divides to R common carotid and right subclavian artery
supplies blood to R side of head, neck, upper limb |
|
L common carotid artery
|
left side of head and neck
|
|
left subclavian artery
|
left upper limb...to axillary artery
|
|
descending thoracic aorta
|
turns to abdominal aorta posterior to diaphragm
|
|
descending thoracic aorta
|
posterior intercostal artery branches...bulk of supply to intercostal space!
esophageal branches usually bronchial arteries supply to fibrous pericardium |
|
pulmonary trunk
|
divides to L and R pulmonary arteries to respective lungs.
begins at apex of R ventricle. |
|
cardiovascular shadow/silhouette
|
can see L margin of pulmonary trunk in xray
|
|
ligamentum arteriosum
|
b/w root of L pulmonary artery and arch of aorta
|
|
ductus arteriosus
|
in fetus, it shuts blood from pulmonary trunk into the underside of arch of aorta. to bypass lungs.
|
|
posterior side of heart
|
formed by pulmonary veins. L, R, each of which have superior and inferior sections
|
|
pericardium
|
has two pericardia: fibrous and serous
|
|
serous pericardium
|
parietal layer (behind fibrous pericardium), visceral layer (on heart)...and pericardial cavity
|
|
fibrous pericardium
|
outer layer that covers the heart
continuous of adventitial layer of great vessels fuses with central tendon and tethers to sternum |
