Suggest why arteries close to the heart have more elastic fibres in their walls than arteries further away from the heart?

Text Solution

Verified by Experts

1. Elastic fibres allow the artery to stretch and recoil as blood passes through it.
2. Arteries closer to the heart experience more pressure than arteries further away from the heart.
3. Therefore arteries close to the heart have more elastic fibres in their walls to cope with high pressure of blood coming from the heart.
