Q

What is the difference between deep veins and superficial veins?

A

deep veins accompany arteries, (meaning along with an artery there will be a deep vein)

ex: cephalic vein is not a deep vein, so it doesn’t have an artery alongside

Q

In the calf, we have something called “venae comitantes”, what is that?

A

venae comitantes = corresponding veins (paired deep vein, the 2 veins surround 1 artery)

ex: all calf veins PTV, ATV, PER, and Brachial

Q

What is another name for below the calf, superior to medial malleolus where the perforators veins are most found?

24
Q

What are communicating vein?

Study These Flashcards
A

veins that connect vessels of the same system
ex: superficial to superficial, deep to deep

25
What are venous sinuses (soleal sinuses)?
little pockets or potential reservoirs/channels that will allow the blood to accumulate inside the calf muscle and during calf contraction, it pushes or ejects the blood into the PER and PTV
26
Soleal sinuses (venous sinuses) drains into ...
deep calf veins
27
Perforating veins drain blood from _______ vein to _______ vein.
superficial vein to deep vein
28
SSV drains blood into ...
popliteal vein
29
GSV drains blood into ...
CFV
30
Where does the IVC orginate?
the confluence of Rt CIV and Lt CIV
31
Rt Renal Vein and Lt Renal Vein drain blood into ...
IVC
32
Hepatic veins drain blood from _____ and that blood drain into _____
- drain from liver - drain into IVC
33
The IVC terminates at which point?
Rt atrium
34
What are the venae comitantes in upper extremities?
radial, ulnar, brachial
35
What are the superficial veins in upper extremities?
cephalic, basilic
36
Radial vein and ulnar vein drain into which vein?
brachial vein
37
Which vein is formed at the confluence of brachial vein and basilic vein?
axillary vein
38
Where does the subclavian vein originate?
at the confluence of cephalic and axillary vein
39
Which 2 veins join together to form the innominate vein?
subclavian vein and IJV
40
What is the anatomy difference between arterial and venous?
venous has Lt & Rt innominate veins, while arterial only has Rt innominate artery
41
When does the Lt subclavian vein terminate?
at the Lt innominate vein
42
What are the 3 layers of the vein?
intima, media, adventitia
43
What is the difference between vein layers and artery layers?
the medial layer (media) of the vein is thinner than artery, that's why vein is collapsible and artery is not
44
What type of valve does vein have?
bicuspid valve (extension of intimal layer)
45
What is the purpose of venous valves?
prevent backflow and maintain unidirectional flow (fight against gravity)
46
Since the gravity or the hydrostatic pressure would be greatest closest to the ankle, we have the most ________ in calf veins.
valves
47
The number of valves DECREASE/INCREASE as it gets close to abdomen.
DECREASE
48
How many valves are found in veins in chest and abdomen?
no valves ex: IVC, SVC iliac veins, etc
49
Arms have how many valve per vein?
1 per vein
50
Perforators have how many valve?
at least 1
51
What forms the confluence of the IVC? A. hepatic veins B. renal veins C. common iliac veins D. right atrium
C. common iliac veins
52
In which vessel does blood flow from the cephalic vein? A. axillary vein B. innominate vein C. brachial vein D. jugular vein
B. innominate vein
53
Which vessel contains no valves? A. common femoral vein B. perforating veins C. axillary vein D. superior vena cava
D. superior vena cava - most valves = most distal - chest/abdomen = no valves
54
Where does the popliteal vein originate? A. confluence of the ATV and TP trunk B. Hunter's canal C. confluence of the PTV and peroneal D. distal femoral vein
A. confluence of the ATV and TP trunk
55
Where does the common femoral vein terminate? A. deep femoral vein and femoral vein B. inferior vena cava C. external iliac vein D. saphenofemoral junction
C. external iliac vein
