Answer:

Physical (Physiological) differences between veins and arteries:

Arteries	Vein
Arteries carry pure (oxygenated ) blood to the different parts of the body and organs	Veins carry impure (deoxygenated) blood to the heart.
Arteries walls are thick, rigid and muscular	Venous walls are thin and easily collapsible
Thick walled arteries consists of three layers of tunica	Veins have thin walled and comparatively wider lumen
Arteries are red in colour	Veins are blue in colour
Arterial wall "Tinica intima" have simple squamous epithelium	Venous wall "Tunica externa" consists of elastic connective tissue and less elongated endothelial cells
Tunica media of arteries are muscular	Tunica media of veins are less muscular
Arteries are flexible	Veins are comparatively less flexible
There are no valves in arteries	Valves are present in veins for unidirectional movement of blood
Arteries are deeply positioned within body	Veins are positioned closer to the surface of skin
