Anatomy QIII:QVI

Veins and Fetal Circulatory Structures

returns blood from body regions superior to the diaphragm superior vena cava
returns blood from body regions inferior to the diaphragm inferior vena cava
the inferior and superior vena cava empty into right atrium
drain most of the blood of the brain dural sinuses
the dural sinuses empty into the internal jugular veins
the most inferior portion of the dural sinuses sigmoid sinus
these dural sinuses become the internal jugular veins sigmoid sinuses
where are the dural sinuses located? between the layers of the dura mater
two layers of the dura mater periosteal layer, meningeal layer
three veins of the head and neck internal jugular, external jugular, vertebral
superiorly, lies lateral to the internal carotids and inferiorly, lies lateral to the common carotids internal jugular veins
the internal jugular vein joins the subclavian vein at the base of the neck to form the BLANK vein 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
do the external jugular veins have a corresponding artery? no
where do the external jugular veins empty into? subclavian vein
drain the cervical vertebrae, cervical spinal cord, and muscles in the superior neck region vertebral veins
a multivein bundle venous plexus
the vertebral veins descend through C1-C6 through the transverse foramina as a single vein, true or false? false
the vertebral veins exit which vertebra to form a single vein C6
the singular vertebral vein continues inferiorly to join which vein at the root of the neck? brachiocephalic
deep veins of the upper limbs have the same names as their companion arteries, true or false? true
superficial veins are BLANK than deep veins larger
starts at the lateral side of the hand's dorsal venous network, bends around the distal radius to enter the anterior forearm, ends inferiorly at the clavicle cephalic vein
starts at the medial aspect of the hand's dorsal venous network, ascends along the posteromedial forearm and the anteromedial surface of the arm basilic vein
the basilic vein joins the BLANK vein to become the BLANK vein brachial vein, axillary vein
the cephalic vein joins the BLANK vein axillary
on the anterior aspect of the elbow joint in the antecubital fossa, connects the basilic and the cephalic veins median cubital veins
ascends in the center of the forearm, its termination point at the elbow is highly variable median vein of the forearm
this system drains oxygen-poor blood from the intercostal spaces azygos system
blood from the first few intercostal spaces empties into the BLANK veins brachiocephalic
the azygos system empties into the superior vena cava
three veins in the azygos system azygos vein, hemiazygos vein, accessory hemiazygos 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 the level of this vertebra, the azygos vein arches over the vessels of the right lung to join the superior vena cava T4
ascends on the left side of the vertebral column, corresponds to the inferior half of the azygos on the right, about midthorax it runs horizontally across the vertebrae to join the azygos vein hemiazygos
the superior continuation of the hemiazygos accessory hemiazygos vein
these veins exit the liver superiorly and empty into the most superior part of the inferior vena cava hepatic veins
these veins carry all the blood that originated in the digestive organs in the abdominopelvic cavity hepatic veins
a specialized part of the vascular circuit which picks up digested nutrients from the stomach and intestines and delivers them to the liver for processing and storage hepatic portal system
a series of vessels in which two separate capillary beds lie between the arterial supply and the final venous drainage hepatic portal system
what is the vessel that interconnects the capillary bed networks of the hepatic portal system? hepatic portal vein
what vessels drain the entire hepatic portal system? hepatic veins
where do the hepatic veins empty into? the most superior region of the inferior vena cava
what are the tributaries of the hepatic portal vein? superior and inferior mesenteric veins, splenic vein
the superficial veins of the pelvis and lower limbs are called saphenous veins
longest vein in the body, empties into the femoral vein great saphenous vein
runs along the lateral side of the foot and then along the back of the leg, empties into the popliteal vein small saphenous vein
these vessels run in the umbilical cord carrying blood to and from the placenta umbilical vessels
FCS: branch from the internal iliac arteries and carry blood to the placenta to pick up oxygen and nutrients paired umbilical arteries
after birth, the paired umbilical arteries become medial umbilical ligaments
FCS: returns blood from the placenta to the fetus umbilical vein
after birth, the umbilical vein becomes ligamentum teres (round ligament)
FCS: shunts some blood away from the fetal liver ductus venosus
after birth, the ductus venosus becomes the ligamentum venosum
FCS: a hole in the interatrial septum foramen ovale
after birth, the foramen ovale becomes the fossa ovalis
FCS: a shunt from the pulmonary trunk to the aortic arch ductus arteriosus
after birth, the ductus arteriosus becomes the ligamentum arteriosum
