Episode notes
Blood Vessel Basics
- Arteries carry oxygenated blood away from the heart, while veins return deoxygenated blood.
- Capillaries, the smallest vessels, facilitate oxygen exchange within tissues.
Artery Aging
- Arteries harden with age, worsened by smoking, diabetes, and environmental factors like smoke exposure.
- This hardening, caused by plaque and calcium deposits, reduces artery flexibility and function.
Vein vs. Artery Structure
- Veins hold 75% of your blood and have valves for blood return, aided by breathing.
- Arteries, fueled by the heart's pumping, are thicker, stronger, and lack valves.
