Flashcards in vessels and circulation #2 Deck (43):
1

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.

2

where is the inferior vena cava in relation to the descending abdominal aorta.

it lies to the right of the descending aorta

3

left and right brachiocephalic veins

the veins that drain the head, neck, and upper limbs merge together to form these veins.

4

superior vena cava

the left and right brachiocephalic veins merge to form this vein

5

internal jugular vein

lies deep to the sternocleidomastoid muscles and eventually merges with the subclavian vein to form the brachiocephalic vein

6

external jugular vein

travels superficial to the sternocleidomastoid muscle

7

vertebral veins

extend through the transverse foramina of the cervical vertebrae and drain into the brachiocephalic veins

8

dural venous sinuses

most of the venous blood of the cranium drains through these

9

cavernous sinus

receives input from the superior ophthalmic veins and the inferior ophthalmic veins that drain the skin in the region of the nose

10

Where does most of the blood from the dural venous sinuses collect

the internal jugular veins

11

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

12

bronchail veins

drain into the azygous system of veins

13

esophageal veins

drain the esophageal wall and travel to the azygous vein or the left gastric vein

14

superior phrenic veins

merge with the inferior vena cava

15

inferior phrenic veins

merge with the inferior vena cava

16

musculophrenic veins

travel through the branches that eventually lead to the brachiocephalic veins

17

hepatic portal system

inferior mesenteric vein, splenic vein, and the superior mesenteric vein all merge in this system

18

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

19

hepatic portal vein

receives oxygen poor, but nutrient rich, blood from the gastrointestinal organs. intestines, pancreas, spleen, stomach, gallbladder

20

sinusoids

liver capillaries

21

where do veins of the organs and structures of the pelvis and perineum merge

the internal iliac veins

22

dorsal venous arch (on hand)

drains into both the basilic vein and the cephalic vein

23

basilic vein

runs adjacent to the medial surface of the upper limb and eventually help form the axillary vein

24

cephalic vein

runs alongside the lateral aspect of the upper limb and eventually drains into the axillary vein

25

medial cubital vein

connects the cephalic and basilic vein

26

venipuncture

vein is punctured to draw blood or inject medication

27

where do the digital and palmar venous arches drain

pairs of radial veins and ulnar veins

28

brachial veins

at the cubital fossa the radial and ulnar veins merge

29

axillary vein

the brachial and basilic veins merge

30

subclavian vein

superior to the lateral border of the first rib the axillary vein is renamed to the subclavian vein

31

where does the dorsal venous arch of the foot drain

the great saphenous and the small saphenous veins

32

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

33

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

34

where do the digital veins and posterior tibial v eins drain

into pairs of anterior tibial veins and posterior veins

35

pulmonary trunk

artery immediately after the right ventricle

36

left and right pulmonary arteries

branches of the pulmonary trunk that lead to the lungs

37

pulmonary veins

leave lungs and take newly oxygenated blood to the left side of the heart

38

Golden hour

trauma to pulmonary veins requires surgery within an hour

39

what does the umbilical vein turn into

ligamentum teres

40

what do the umbilical arteries turn into

medial umbilical ligaments

41

what does the ductus venosus turn into

ligamentum venosum

42

septum primum

flap that closes off the fossa ovale at birth

43

what does the ductus arteriosus turn into

ligamentum arteriosum
