Study Notes

Blood Vessel Layers

The tunica interna is the innermost layer, thin and provides elasticity.
The tunica media is the middle layer, responsible for vasoconstriction (narrowing of the blood vessel).
The tunica externa is the outermost layer, providing structural support.

Arteries Supplying Specific Structures

Upper Limb: Subclavian Artery
Head & Brain: Common Carotid Artery
Lower Limb/Pelvis: Common Iliac Artery
Intestines: Superior Mesenteric Artery
Spine: Vertebral Artery
Anterior/Lateral Arm: Cephalic Vein (Note: veins are not the primary vessels supplying blood. Veins primarily drain blood from regions.)
Liver, Spleen, Stomach: Celiac Artery

Abdominal Aorta Branches

The celiac trunk supplies the liver, gallbladder, stomach, and spleen.
The superior mesenteric artery supplies the small intestine and portions of the large intestine.
The inferior mesenteric artery supplies portions of the large intestine.
