Question

It is said that arteries are more elastic and contractile than veins comment ​

Answer 1

Answer:

Arteries are more elastic than veins because they are designed to withstand tremendous blood pressures.

Veins, on the other hand, contain blood at relatively low blood pressure. That's why they have evolved valves to prevent the blood from going backwards.

Answer 2

$\huge\underline\mathbb\red{{♡ANSWER♡}}$

$\blue\longmapsto\:$ Arteries are more elastic because they have to cope up with high pressure blood pumped from the heart.The pressure at the major arteries is more than in the minor arteries.

$\blue\longmapsto\:$ In veins the pressure is less.So they have walls with minimum elasticity
