Answer 1

Arteries, veins and capillaries. There are three main types of blood vessels:arteries take blood away from the heart to the body organs and tissues. The artery wall is thick and muscular so it can withstand the high pressure of the blood being pumped directly from the heart.

the arteries are the vessels which deliver oxygen rich blood from the heart to the tissues present in our body.They have valves in them and are thick walled

Veins are the vessels whic carry blood towards the heart they deliver deoxygenated blood.They are thin walled

Cappilaries deliver oxygenated blood from arteries to the tissues of the body
