vessels and circulation #2 Flashcards
inferior vena cava
veins inferior to the diaphragm merge to collectively form this vein, which is the largest diameter of any vessel in the body.
where is the inferior vena cava in relation to the descending abdominal aorta.
it lies to the right of the descending aorta
left and right brachiocephalic veins
the veins that drain the head, neck, and upper limbs merge together to form these veins.
superior vena cava
the left and right brachiocephalic veins merge to form this vein
internal jugular vein
lies deep to the sternocleidomastoid muscles and eventually merges with the subclavian vein to form the brachiocephalic vein
external jugular vein
travels superficial to the sternocleidomastoid muscle
vertebral veins
extend through the transverse foramina of the cervical vertebrae and drain into the brachiocephalic veins
dural venous sinuses
most of the venous blood of the cranium drains through these
cavernous sinus
receives input from the superior ophthalmic veins and the inferior ophthalmic veins that drain the skin in the region of the nose
Where does most of the blood from the dural venous sinuses collect
the internal jugular veins
azygous vein
receives venous drainage from the veins of the lumbar region, the sacral region, the intercostal muscles, the bronchi, esophagus, and pericardium. it then merges with the superior vena cava
bronchail veins
drain into the azygous system of veins
esophageal veins
drain the esophageal wall and travel to the azygous vein or the left gastric vein
superior phrenic veins
merge with the inferior vena cava
inferior phrenic veins
merge with the inferior vena cava
musculophrenic veins
travel through the branches that eventually lead to the brachiocephalic veins
hepatic portal system
inferior mesenteric vein, splenic vein, and the superior mesenteric vein all merge in this system
portal system
the veins that drain one group of capillaries dilver blood to another group of capillaries, which then are drained by the usual venules and veins that lead to the vena cava and the right atrium of the heart
hepatic portal vein
receives oxygen poor, but nutrient rich, blood from the gastrointestinal organs. intestines, pancreas, spleen, stomach, gallbladder
sinusoids
liver capillaries
where do veins of the organs and structures of the pelvis and perineum merge
the internal iliac veins
dorsal venous arch (on hand)
drains into both the basilic vein and the cephalic vein
basilic vein
runs adjacent to the medial surface of the upper limb and eventually help form the axillary vein
cephalic vein
runs alongside the lateral aspect of the upper limb and eventually drains into the axillary vein
medial cubital vein
connects the cephalic and basilic vein
venipuncture
vein is punctured to draw blood or inject medication
where do the digital and palmar venous arches drain
pairs of radial veins and ulnar veins
brachial veins
at the cubital fossa the radial and ulnar veins merge
axillary vein
the brachial and basilic veins merge
subclavian vein
superior to the lateral border of the first rib the axillary vein is renamed to the subclavian vein
where does the dorsal venous arch of the foot drain
the great saphenous and the small saphenous veins
great saphenous vein
is the longest vein the in the body. originates in the medial side of the ankle and extend adjacent to the medial side of the entire lower limb before it drains into the femoral vein
small saphenous vein
extends adjacent to the lateral side of the ankle and then travels along the posterior calf before draining into the popliteal vein
where do the digital veins and posterior tibial v eins drain
into pairs of anterior tibial veins and posterior veins
pulmonary trunk
artery immediately after the right ventricle
left and right pulmonary arteries
branches of the pulmonary trunk that lead to the lungs
pulmonary veins
leave lungs and take newly oxygenated blood to the left side of the heart
Golden hour
trauma to pulmonary veins requires surgery within an hour
what does the umbilical vein turn into
ligamentum teres
what do the umbilical arteries turn into
medial umbilical ligaments
what does the ductus venosus turn into
ligamentum venosum
septum primum
flap that closes off the fossa ovale at birth
what does the ductus arteriosus turn into
ligamentum arteriosum
