1. Blood vessels of the head and face

2. Arteries
Carry oxygenated blood away from the heart to cells and tissue
Can detect a pulse
‘spurt’ w/ cut or severed
Aorta = largest artery of the body

3. Veins Carry deoxygenated blood from cells and tissues to the heart.
More superficial than arteries
Closer to the skin
‘bluish’ in color
Do not ‘spurt’ when cut

4. Carotid artery aka Common carotid artery
Main blood supply for the
Head
Neck
Face
Mouth

5. Divisions of the carotid artery
Internal
Delivers blood to the
Brain
Eyes
External
Face
Oral cavity

6. External division
Arteries are named after the area of the body they supply blood to. (just like the nerves.)
Posterior Superior artery
Delivers blood to Max. molars
Middle Superior artery
Delivers blood to Max. premolars
Anterior Superior artery
Deliver blood to Max. anterior teeth
All are branches off of the Maxillary artery

7. External division Lingual artery Inferior Alveolar artery
Delivers blood to the tongue
Inferior Alveolar artery
Delivers blood to the mandibular teeth
Mental artery
Delivers blood to the chin
All are branches off of the mandibular artery

8. Jugular vein 2 main divisions Internal External Drains blood from
Brain
Eyes
External
all other tissues of the head and face

Superficial veins
Facial vein
Deep facial vein
Retromandibular vein
Lingual vein
Deep veins
Maxillary vein
Pterygoid plexus of veins.
All veins lead to the
Superior vena cava
Which drains blood into the R. atrium of the heart.
