Why artries are thick walled and veins are thin walled |
|
Answer» Since the emerges under high pressure in the arteries so, it is thick walled, elastic..veins don\'t need thick walls bcoz\' blood is no longer under high pressure ND so they have thin walls inspite they too have valves to ensure blood flow.. Becouse blood jada pressure se heart se aata he use jhelne ke liye arteries ki wall thick hoti he or veins me blood jada pressure se flow nhi krta he isliye uski walls thin hoti he |
