Arteries

The aorta

Arcus aortae and its branching

Circle of Willis

Ascending aorta – Aorta ascendens

• Right and left coronary arteries – Arteria coronaria dextra et sinistra

Aortic arch – Arcus aortae

• Brachiocephalic trunk – truncus brachiocephalicus

Right common carotid artery – arteria carotis communis dextra

Right subclavian artery – arteria subclavia dextra

Left common carotid artery – arteria carotis communis sinistra

Left subclavian artery– arteria subclavia sinistra

• • Common carotid artery – arteria carotis communis

Internal carotid artery – arteria carotis interna

External carotid artery – arteria carotis externa

– Supply the head and neck with oxygenated blood

• • Subclavian artery – arteria subclavia

Axillary artery – arteria axillaris

Brachial artery – arteria brachialis

Radial artery – arteria radialis

Ulnar artery – arteria ulnaris

– Blood supply to the upper extremity

Descending aorta – Aorta descendens

• Thoracic aorta – aorta thoracica

Splenic artery – arteria splenica/lienalis

Gastric artery – arteria gastrica

Hepatic artery – arteria hepatica

• Abdominal aorta – Aorta abdominialis
  • Paired visceral branches:

Suprarenal arteries – arteriae suprarenales

Renal arteries – arteriae renales

Testicular arteries – arteriae testiculares

Ovarian arteries – arteriae ovaricae

• Unpaired visceral arteries:

Superior mesenteric artery – arteria mesenterica superior

Inferior mesenteric artery – arteria mesenterica inferior

– Blood supply to the guts

Right common iliac artery – arteria iliaca communis dextra

Left common iliac artery – arteria iliaca communis sinistra

• • Common iliac artery – arteria iliaca communis

Internal iliac artery – arteria iliaca interna

External iliac artery – arteria iliaca externa

Femoral artery – arteria femoralis

Anterior tibial artery – arteria tibialis anterior

Posterior tibial artery – arteria tibialis posterior

– Blood supply to the lower extremity

Blood supply of the brain

The blood goes to the brain by:

2 internal carotid arteries – arteria carotis interna dextra et sinistra

2 vertebral arteries – arteriae vertebrales

At the brain stem level the vertebral arteries join together, forming the basilary artery – arteria basilaris. The basilar artery together with internal carotid arteries create the circle of Willis.
