Difference between arteriole and venule

Arteriole	Venule
Arterioles distribute blood to capillary beds, the sites of exchange with the body tissues.	Blood of capillaries lead back to small vessels known as venules that flow into the larger veins and eventually back to the heart.
·         The lumina of arteriole are much smaller than corresponding venule	·         The lumina of venules are much larger  than corresponding arterioles.
·         It is also known as resistance vessel	It is also known as capacitance vessel
·         The walls of the arteriole are much thicker  than venule	·         The walls of the veins are much thinner than arterioles
Arteriole provides 50% peripheral resistance	·         Veins and venules can withstand a much lower pressure from the blood flowing through them. Their lumens are correspondingly larger in diameter to allow more blood to flow with less vessel resistance.
