1.General Description
2.Blood Vessels of Pulmonary Circulation
3. Arteries of Systemic Circulation
Guo Ling, MD,PhD Department of Anatiomy
ARTERY
1) A main A-trunk lies in a certain part of body
2) Part: marking the start and the end of an artery
3) Branches (1st ,2nd, 3rd… in grade, from a large D
to a small D)
Parietal and visceral branches exist in the trunk.
4) Symmetrical or bilateral arrangements
5) Accompanied with V and N
The purpose is to better understand the name, main
branches and specific supply targets of an artery.
General Description 1.Organ-Extrinsic Distribution Patterns of Artery
2. Organ-Intrinsic Distribution Patterns of the Artery
Radiated distribution
Transversal distribution
Longitudinaldistribution
HilumEntry
Point entry
3. Patterns of Anastomoses of Arteries
Communicating branches
Arterial arch Network Arteriovenous anastomoses
Some parts of the body build up arterial anastomoses to ensure constant blood supply to the specific areas or organs because these regions or organs often change their shape or are pressed & their blood flow is affected.
Trunk of artery
Collateral branches
4. Collateral Circulation
Composition of Pulmonary Circulation
3) Arterial ligament ( ductus arteriosus) (position ,clinic significance,CHD)
2) Pulmonary veins (4 in number)
contain venous blood.
1) Pulmonary trunk ,left and right pulmonary arteries
contain arterial blood.
Arteries of Systemic Circulation
Division
branches of the aorta
Aorta
Aortic arch
Ascending aorta
Descending aorta
Thoracic aorta
Abdominal aorta
Left \ Right coronary arteries
1. Branches of Ascending Aorta
3) Left subclavian artery
2) Left common carotid
1) Brachiocephalic trunk
2. Branches of Aortic Arch (three branches, R→L )
R. subclavian artery
R. common
carotid
Brachocephalic trunk
( brain ,visual organ.no branches outside the skull)
External carotid
Internal carotid
⑥Superficial temporal A
⑤Maxillary A Middle meningeal A
④Occipital A
③ Facial A
②Lingual A
①Superior thyroid A
Common Carotid Branches
Carotid Sinus
situated in the proximal
part of internal carotid
pressure-receptor
chemoreceptor
Carotid Body
situated behind the ramification of common carotid
Branches of Subclavian Artery
Axillary A
②Internal thoracic A
①Vertebral A
③Thyrocervical trunk
④Costocervical trunk
Superficial and Deep palmar arches
Axillary A
Brachial A
Radial A , Ulnar A
Subclavian A is the main trunk of the upper limb.

The use of brachial A in measuring blood pressure
● Brachiocephalic trunk gives off branches behind the right sternoclavicular joint.
● Left common carotid originates from aortic arch. Right common carotid arises from brachiocephalic trunk.
Summary
● Common carotid
gives off its branches
opposite the upper
border of
thyroid cartilage.
