Thoracic Abdominal
Distributes O2 rich blood to entire body except alveoli of lungs
Ascending Aorta
Branches right and left cornary arteries
Supplies muscle wall and septa of heart with blood
Aortic arch
Superior mediastinum
Behind manubrium and ends at T4

T4
Aortic arch branches into

Left common carotid
Left subclavin
Brachiocelphalic artery location
Lies at level of right sternoclavicular joint
Brachiocephalic artery divides into
Right common carotid artery
-supplies blood to head and neck
Right subclavian artery
-supplies blood to right upper limb
Left common carotid artery
Arises at height of aortic arch
Supplies left side of head and neck
Passes upward and obliquely into neck
Left common carotid artery bifucates at
C4/C5 level of thyroid cartilage
External carotid artery
Internal carotid artery
Commom carotid arteries
Both pass upwards on either side of neck
Embedded in a fascia called the carotid sheath at upper thyroid cartilage C4/C5 divides into external and internal carotid arteries
The commom carotid ateries are embedded in a fascia called
Carotid sheath
