Study Notes
Blood Vessel Structure and Function
- Capillaries: Tiny vessels connecting arteries and veins.
- Arteries: Blood vessels carrying blood away from the heart.
- Veins: Blood vessels carrying blood toward the heart.
- Arterioles: Smallest branches of arteries.
- Venules: Smallest branches of veins.
Vessel Wall Layers (Tunics)
- Tunica Intima (Inner): Endothelial layer, connective tissue, elastic layer.
- Tunica Media (Middle): Smooth muscle, elastic tissue, collagenous tissue.
- Tunica Adventitia (Outer): Loose connective tissue, smooth muscle bundles, elastic tissue.
Arteries vs. Veins
- Thicker Tunica Media: Arteries
- Larger Diameter: Veins
- More Pulsatile: Arteries
- Collapsible Tubes: Veins
- Valves prevent backflow: Veins (not heart valves)
- Faster Blood Flow: Arteries
- Thinner Tunica Media: Veins
- Aided by skeletal muscle contractions: Veins
Major Abdominal Aorta Branches
- Celiac Axis: Anterior branch of the abdominal aorta.
- SMA: Superior mesenteric artery, anterior branch.
- Renal Arteries: Lateral branches of the abdominal aorta.
- IMA: Inferior mesenteric artery, anterior branch.
Major Aortic Arch Branches
- Innominate (Rt Brachiocephalic Artery): First branch from the aortic arch.
- LT CCA: Left common carotid artery, second aortic arch branch.
- LT Subclavian Artery: Third branch from the aortic arch.
