Veins and Fetal Circulatory Structures
Question | Answer |
---|---|
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 |
