Think and answer.
1. Why are arteries thick-walled while veins are thin-walled?​

Answer 1

Explanation:

Blood flows from the capillaries into very small veins called venules, then into the veins that lead back to the heart. Veins have much thinner walls than do arteries, largely because the pressure in veins is so much lower.

Answer 2

Answer:

Arteries are thick walled because they need much pressure to pump the blood throughout the body and thick walls provide that pressure. ... The pressure in our arteries is more than in veins as the blood has to reach throughout our body.
