Study Notes
Blood Vessels
- Arteries carry blood away from the heart.
- The central blood-containing space surrounded by tunics is called the lumen.
- Capillaries contact tissue cells and directly serve cellular needs.
Types of Blood Vessels
- The three major types of blood vessels are arteries, veins, and capillaries.
- Arteries and veins have three main components: tunica interna, tunica media, and tunica externa.
Regulation of Blood Vessels
- The tunica media layer regulates vasoconstriction and vasodilation.
Capillaries
- Continuous, fenestrated, and sinusoidal capillaries are found in specific types of blood vessels.
- The largest blood pressure fluctuations are smoothed out in arterioles.
Capillary Structure
- Fenestrated capillaries have a thin tunica interna and allow only a single red blood cell to pass at a time.
- The cuff of smooth muscle that surrounds each true capillary and regulates blood flow into the capillary is called a precapillary sphincter.
