Anatomy Q3

Veins

DefinitionTerm
brain drainage dural sinuses
digestive system drainage hepatic portal system
returns blood from body regions superior to the diaphragm superior vena cava
returns blood from body regions inferior to the diaphragm inferior vena cava
empty into the right atrium superior & inferior vena cava
superior & inferior sagittal sinuses, straight sinus, transverse sinuses, sigmoid sinus dural sinuses
drain most of the blood of the brain dural sinuses
empty into the internal jugular veins dural sinuses
s-shaped sigmoid sinuses become the ____ ____ veins internal jugular
located between the layers of cranial dura mater dural sinuses
veins of the head & neck internal jugular veins, external jugular veins, vertebral veins
superiorly, lies lateral to the internal carotids, and inferiorly, lies lateral to the common carotids internal jugular veins
at the base of the neck, the internal jugular veins joins with the ____ vein to from the ____ vein subclavian; brachiocephalic
descends through the neck on the surface of the SCM external jugular veins
superiorly, its tributaries drain the posterior scalp, lateral scalp, and some of the face external jugular veins
are not accompanied by any corresponding artery external jugular veins
empty into the subclavian vein external jugular veins
unlike the ___ arteries, the ____ veins do not serve much of the brain vertebral
draining the cervical vertebrae, cervical spinal cord, and muscle in the superior neck region vertebral veins
originating inferior to the occipital condyle, each vertebral vein descends through the transverse foramina of vertebrae C1-C6 in the form of s venous plexus vertebral veins
exit from C6 as a single vein, continue inferiorly to join the brachiocephalic vein in the root of the neck vertebral veins
follow the paths of companion arteries; have the same names as the companion arteries deep veins of the upper limbs
superficial veins are larger than the deep veins upper limbs
visible beneath skin, frequent anastomoses superficial veins of the upper limbs
superficial veins of the upper limbs cephalic, basilic, median cubital, median vein of the forearm
starts at lateral side of the dorsal venous network, bends around the distal radius to enter the anterior forearm. then, this vein ascends through the anterolateral side of the entire limb & ends inferior to the clavicle, where it joins the axillary vein cephalic vein
arises from the medial aspect of the hand's dorsal venous network, then ascends along the posteromedial forearm and the anteromedial surface of the arm. in the axillary region, this vein joins the brachial vein to become the axillary vein basilic vein
on the anterior aspect of the elbow joint, in the region called the antecubital fossa, this vein connects the basilic & cephalic veins median cubital vein
often used for a blood draw or IV line median cubital vein
ascends in the center of the forearm; its termination point at the elbow is highly variable median vein of the forearm
blood draining from the first few intercostal spaces empties into the ___ veins brachiocephalic
blood draining from the other intercostal spaces drains into a group of veins called the ____ ____ azygos system
drains intercostal spaces; empties into the superior vena cava; comprised of azygos vein, hemiazygos vein, & accessory hemiazygos vein azygos sytem
name means unpaired azygos vein
ascends along the right or the center of the thoracic vertebral bodies azygos vein
receives all of the right posterior intercostal veins, plus the subcostal vein azygos vein
at about the level of T4, the ____ arches over the great vessels that run into the root of the right lung and joins the superior vena cava azygos vein
ascends on the left side of the vertebral column, corresponds to the inferior half of the azygos on the right hemiazygos vein
at about midthorax, the ___ runs horizontally across the vertebrae and joins the azygos vein hemiazygos vein
superior continuation of the hemiazygos; course along the right to join the azygos vein accessory hemiazygos vein
blood returning from the _____ _____ and the ____ wall reaches the heart via the inferior vena cava abdominopelvic viscera; abdominal
most venous tributaries of this great vein share the names of the corresponding arteries inferior vena cava
the right & left ___ veins exit the liver superiorly and empty into the most superior part of the inferior vena cava hepatic
these veins carry all the blood that originated in the digestive organs in the abdominopelvic caivty and arrived via the ____ portal system hepatic
a specialized part of the vascular circuit hepatic portal system
picks up digested nutrients from the stomach and intestines and delivers these nutrients to the liver for processing and storage (ditto for toxins) hepatic portal system
series of vessels in which two separate capillary beds lie between the arterial supply and the final venous drainage hepatic portal system
share the same name of the accompanying artery deep veins of the pelvis & lower limbs
empties into the femoral vein great saphenous vein
superficial veins of the pelvis & lower limbs great saphenous vein & small saphenous vein
longest vein in the body great saphenous vein
ascends along the medial side to empty into the femoral vein just distal to the inguinal ligament great saphenous vein
empties into the popliteal vein small saphenous vein
runs along the lateral side of the foot and then along the posterior calf small saphenous vein
posterior to the knee, it empties into the popliteal vein small saphenous vein
multivein bundles venous plexuses
