Q

What vessels carry oxygenated blood to the brain

Study These Flashcards
A
  • R/L Vertebral A
  • R/L Carotid A
25
Why do we have the circle of Willis
To protect brain from injury and allow constant blood flow
26
Subclavian Artery supplies what in the body
- Supplies blood to head, upper extremity and thorax
27
What does subclavian artery become
- Axillary artery - **AT 1ST RIB**
28
2 Major Branches of Axillary Artery
- internal thoracic artery - vertebral artery
29
What is internal thoracic artery used for
CABG
30
Axillary Artery Becomes... and where ?
Brachial artery - after it passes through teres major
31
Axillary Artery supplies...
scapula, humerus, shoulder, thoracic muscles
32
Brachial Artery Branches at.... into....
- antecubital fossa - radial artery - ulnar artery
33
Thoracic/Descending Aorta is at what vertebral level
T4/5 - T12 - *aortic hiatus in diaphragm
34
6 Arteries that branch off abdominal aorta (Visceral)
1. Celiac Trunk 2. Superior Mesenteric A 3. Renal A's 4. Gonadal A's 5. Inferior Mesenteric A 6. Lumbar A's
35
Abdominal Aorta Arteries that project anteriorly
Celiac Trunk Superior Mesenteric A Injerior Mesenteric A
36
Abdominal Aorta A's that project L/R
- renal A - Gonadal A - Lumbar A
37
Celiac Trunk Branches into
1. Left Gastric A 2. Splenic A 3. Common Hepatic A
38
Splenic Artery Divides into
1. Pancreatic A
39
Common Hepatic A divides into
1. Hepatic Artery Proper (30% of blood to the liver) 2. Right Gastric A 3. Gastroduodenal A (supplies sup part of duodenum)
40
Describe All paths from Celiac Trunk
41
Superior mesenteric artery supplies...
Ascending and Transverse Colon terminal ileum cecum appendix
42
Inferior Mesenteric Artery
Supplies descending, sigmoid, colon, rectum
43
Abdominal Aorta Terminates at ... and branches into ...
- L4 - R/L common iliac arteries
44
Common Iliac Artery branches into 6 things...
1. Internal Iliac Artery 2. External Iliac Artery - femoral - popliteal - anterior tibial - posterior tibial - fibular artery
45
Functions of Veins
Return blood to the heart
46
Deep Veins Function
- travel alongside the artery and have the same name
47
Superficial Veins Function
- located beneath the skin - clinically important for giving injections and withdrawing blood
48
Deoxygenated Blood returns to which chamber of the heart from systemic veins (which 3)
right atrium 1. coronary sinus 2. SVC 3. IVC
49
What does the SVC do
receives blood from all veins above the diaphragm
50
3 major veins of the head and neck
1. Internal Jugular Veins 2. External Jugular Veins 3. Vertebral Veins
51
What does the IVC do
- larges vein - receives blood from all veins below the diaphragm
52
Label the Sinuses 1. 2. 5. 6. 10. 11.
53
Pathway of Vertebral/Jugular veins to SVC
- Subclavian + Internal Jugular Vein = Braciocephalic Vein - Rt/Lt Brachiocephalic Vein = SVC
54
Label
A: Right vertebral vein B: Right external Jugular Vein C: Subclavian Vein D: Right internal Jugular Vein E: Right Axillary Vein F: Right brachiocephalic Vein
55
Do deep or superficial veins have more valves
Deep (skeletal muscle pump)
56
Label
57
Deep Veins of the Upper Limb
- Radial and Ulnar Veins join at elbow - Brachial Vein Joins Basilic - Basilic becomes axillary - axillary connects to subclavian at lateral border of the first rib
58
Superficial Veins of the Upper Limb
- Cephalic Joins Axillary Vein (Lateral Side) - Basilic joins brachial vein (Medial Side) Median Antebrachial joins basilic or median cubital
59
What is the preffered site fir vein puncture
Antecubital Vein
