Download right and left brachiocephalic veins

Lab 8: Blood Vessels
Identify the great arteries and veins of the upper part of the body: right and left
internal jugular and subclavian veins; right and left brachiocephalic veins; superior
vena cava (SC ); the azygos vein; arch of the aorta and the descending thoracic
aorta; pulmonary trunk, right and left pulmonary arteries and ligamentum arteriosum
connecting the aortic arch and left pulmonary artery noting the course of the left
recurrent laryngeal nerve hooking below the ligamentum and the aortic arch;
brachiocephalic trunk, common carotid (right and left), and subclavian (right and left)
arteries; external and internal carotid arteries; axillary, brachial, radial and ulnar
arteries and corresponding veins and venae comitantes; internal thoracic arteries
and veins, both sides; posterior intercostal arteries and veins, right side; cephalic
vein; basilic vein; median cubital vein.
Identify the following great arteries and veins of the lower part of the body:
abdominal aorta, right and left common iliac arteries and veins, inferior vena cava
(IVC), origins of the celiac trunk, superior and inferior mesenteric arteries, right and
left renal arteries and veins, right and left testicular/ovarian arteries and veins,
inferior phrenic arteries, median sacral artery, origin of right and left internal iliac
artery and the corresponding veins, external iliac arteries and veins, femoral arteries
and veins, popliteal, anterior and posterior tibal arteries and corresponding veins,
great saphenous vein and small saphenous vein.

Asymmetrical paired visceral
(organ) veins that drain to the
IVC include:
Suprarenal Veins
Renal Veins
Gonadal veins
Note: IVC, esophagus, and aorta
pierce the diaphragm at vertebral
levels T8, T10, and T12,
respectively
IVC formed by union of common
iliac veins at ~L5
Common iliac veins formed by
union of ext./int. iliac veins

formed by
junction of Splenic

behind pancreas)
