Study Notes
Veins
- Function to return blood to the heart.
- Include major vessels such as the superior and inferior vena cava.
- Characterized by low blood pressure within these vessels.
- Have thinner walls compared to arteries and primarily transport oxygen-poor blood.
- Some larger veins contain valves that prevent backflow of blood.
Arteries
- Responsible for carrying blood away from the heart.
- The aorta is the largest and a key example of an artery.
- Feature thicker walls and a more substantial tunica media, accommodating higher blood pressure.
Capillaries
- Serve as the sites for nutrient and gas exchange between blood and tissues.
- Venules, small veins, drain blood from these tiny capillary networks.
