Blood vessels like arteries, capillaries, and veins are essential for maintaining blood pressure and delivering oxygen and nutrients to cells. Arteries carry oxygenated blood away from the heart, veins transport deoxygenated blood back to the heart, and capillaries facilitate the exchange of essential substances between blood and cells efficiently.
Insights
- Arteries carry oxygenated blood away from the heart with thick walls to handle high pressure, while veins return deoxygenated blood to the heart using valves to prevent backflow.
- Capillaries, being one cell thick, serve as exchange points for oxygen, carbon dioxide, nutrients, and waste products between blood and cells, connecting arteries and veins in the body's circulatory system.
