Worked Solution & Example Answer:Explain the difference between an artery and a vein Artery - carries oxygen rich blood away from the heart, thick walls, no valves, elastic - Junior Cycle Home Economics - Question 15 - 2009
Step 1
Artery - carries oxygen rich blood away from the heart
Answer
Arteries are blood vessels that transport oxygenated blood away from the heart. They are characterized by thick, muscular walls that provide elasticity, allowing them to withstand the high pressure of blood being pumped from the heart.
Step 2
Vein - carries deoxygenated blood to the heart
Answer
Veins, in contrast, carry deoxygenated blood back to the heart. They have thinner walls compared to arteries and contain valves to prevent the backflow of blood, ensuring it flows in one direction. Blood in veins moves more slowly due to lower pressure.
