Vessels

HideShow resource information
Arteries
Narrow lumen, thicker walls, more collagen, elastic fibres and smooth muscle, no valves.
1 of 5
Veins
Wide lumen, thinner walls, less collagen, elastic fibres and smooth muscle, valves present.
2 of 5
Walls of arteries and veins
Collagen, a tough fibrous protein; strong and durable, elastic fibres; stretch and recoil, smooth muscle; constrict and dilate.
3 of 5
Blood through Vessels
Systole(contracts) blood forced into arteries, elastic walls stretch. Diastole(relaxation) walls recoil to push blood forward. Blood reaches arteries and capillaries> steady flow.
4 of 5
Capillaries
Join arteries and veins, very narrow, walls on
