Question

Give reasons for the following (a) Arteries have thick and elastic muscular walls (b) Arteries are generally not easily seen​

Answer 1

Answer:

a) Arteries have relatively thick muscular walls because blood pressure in them is high and because they must adjust their diameter to maintain blood pressure and to control blood flow.

b) Arteries are not easily seen because arteries are generally thick , present inside the skin as compared to veins,arteries are yellow in colour.

Answer 2

Answer:

If arteries have thin walls they would burst because of high blood pressure. That is why arteries have thick walls. Because the heart pumps blood at high pressure. They must be able to withstand the tremendous pressure from a beating heart.
