Arteries and Veins of Systemic Circulation Flashcards
Where is the descending thoracic aorta found?
Posterior mediastinum
What vertebrae does the descending thoracic aorta run between?
T4 - T12
What is the name of the place where the descending aorta changes?
Aortic hiatus
At the aortic hiatus, what does the descending aorta become?
Abdominal aorta
Name the 5 main branches which come from the descending aorta
- Pericardial branches
- Bronchial arteries
- Oesophageal arteries
- Superior phrenic arteries
- Posterior intercostal arteries
At what vertebral level does the aortic arch begin and end?
T4
Name the 3 branches which come from the arch of the aorta
- Brachiocephalic
- Left Common Carotid
- Left Subclavian
What happens to the brachiocephalic trunk?
Bifurcates into the right common carotid and the right subclavian
What are the main 3 parts of the abdominal aorta?
- 5 paired parietal branches
- 3 paired visceral branches
- 3 unpaired GIT branches
Describe the 5 paired parietal branches of the abdominal aorta
One inferior phrenic artery and four posterior lumbar arteries
Describe the 3 paired visceral branches of the abdominal aorta
Renal arteries, suprarenal arteries and gonadal arteries
Describe the 3 unpaired GIT branches of the abdominal aorta
One celiac trunk, one superior mesenteric artery and one inferior mesenteric artery
At what level does the abdominal aorta bifurcate?
L4
Describe the naming progression of the subclavian artery as the artery descends the upper limb
- Subclavian artery
- Axillary artery
- Brachial artery
- Radial/Ulnar arteries
Where does the subclavian artery become the axillary artery?
Lateral boarder of the first rib
Where does the axillary artery become the brachial artery?
Lower boarder of the teres major
Where does the brachial artery bifurcate?
Cubital fossa
What is the branch which the brachial artery gives rise to immediately distal to the teres major?
Profunda brachii
What are the two major superficial veins of the upper limb?
- Cephalic
2. Basilic
Where do the cephalic and basilic veins originate from?
Dorsal venous network of the hand
On what aspect of the limb does the cephalic vein ascend?
Antero-lateral aspect
Where and how does the cephalic vein terminate?
Within the axilla by joining the axillary vein
What happens the basilic vein at the lower boarder of the teres major?
It moves deep into the arm
What happens after the basilic vein moves deep into the arm?
It combines with venae comitantes of brachial artery to form axillary vein
