Arteries receive blood pumped out from the heart and the blood they receive is under a lot of pressure. This pressure helps the pure blood move quickly through the arteries to far away locations in the body and even when the arteries are running in opposition to gravity. Eg- the common carotid artery running toward the head.
The veins only receive the blood after it has travelled quite far from the heart. Hence the blood pressure in the veins is lesser.
