- 1What are the 5 types of blood vessels?Arteries
Arterioles
Capillaries
Venules
Veins - 2What is the structure of arteries?Elastic tissue stretches and recoils to maintain the high pressure
The endothelium is folded to allow the artery to expand - 3What is the function of arteries?Arteries carry blood from the heart to the rest of the body
- 4What is the structure of arterioles?Arteries branch into arterioles, which are smaller than arteries
They have smooth muscle, but less elastic tissue
The smooth muscle allows them to expand/contract, controlling the amount of blood flowing - 5What is the structure of capillaries?Arterioles branch into capillaries
They are one cell thick
- 6What is the function of capillaries?Substances like C₆H₁₂O₆ and O₂ are exchanged between cells and capillaries
- 7What is the structure of venules?Capillaries connect to venules, which have very thin walls that contain some muscle cells
They join to form veins - 8What is the structure of veins?They have a wider lumen and contain valves to prevent backflow
They have little elastic or muscle tissue
- 9What is the function of veins?Veins take blood back under low pressure
Blood flow is helped by contraction of nearby body muscles
