2. Blood vessels Blood goes through arteries to arterioles to capillaries to venules to veins into either inferior vena cava or superior vena cava at the heart

3. Arteries Carry blood away from the heart toward the capillaries Will carry bright red oxygenated blood with one exception, the pulmonary artery Largest artery is the aorta

4. Arteries Made of an outer layer of connective tissue (tunica externa) and middle layer of smooth muscle (tunica media) Smooth muscle will contract to help move blood along & maintain blood pressure Much thicker in arteries than in veins Most of the force is supplied by the heart

5. Arterioles Small arteries that help maintain bp

6. Capillaries Exchange substances with the cells Fluid, sugar, oxygen, wastes, carbon dioxide Smallest of blood vessels (microscopic) One cell thick membrane

7. Capillaries Carry blood from tiny arterioles into tiny venules There is an exchange between blood & tissue fluid around the cells

8. Veins Collect blood from capillaries & take it back to the heart Will carry “blue” unoxygenated blood with one exception, the pulmonary veins Also made of connective tissue and smooth muscle but not as thick or as strong as arteries

9. Veins Veins do not have the force of the heart behind the blood (the pressure is lost in the capillaries) Gravity, skeletal muscle contractions around the veins, and the veins contracting some themselves help push blood back to the heart

10. Veins Veins have one-way valves to prevent blood from backing up & making sure it keeps moving toward the heart

11. Some major arteries and veins See figures 14-2 and 14-3, pages 438 & 439, and tables 14-1 and 14-2, pages 437 & 440 Know location Some major arteries and veins previously mentioned in Chapter 13 have been left out here.
