Study Notes
2.3 Highways and Byways
- Blood travels in one direction, unlike cars on a two-way street
- Arteries and veins are one-way streets in the body
- Blood travels from arteries to capillaries, then to veins, and back to the heart
- Blood moves due to the heart's pumping action
Veins
- Blood pressure in veins is lower than in arteries
- Veins have one-way valves to prevent backflow
- Valves close when blood tries to flow backwards
- Skeletal muscle contractions squeeze veins, aiding blood flow towards the heart
Arteries
- Blood in arteries flows away from the heart
- High blood pressure requires thick, elastic artery walls
- Artery walls are made of muscle tissue
Capillaries
- Tiny blood vessels connecting arteries and veins
- They facilitate the exchange of oxygen and carbon dioxide
