उत्तर
Arteries are responsible to carry oxygenated blood from the heart to the tissues. The blood
flows in the artery under high pressure and in spurts. If arteries are located superficially then
there is a high possibility of their damage which could lead to a lot of blood loss. To prevent
this damage and blood loss, the arteries are deep seated in the body.
