An arteriole transports oxygenated blood from the arteries to the capillary beds and a venule transports de-oxygenated blood from the capillary beds to the veins.
Artery -> Arteriole -> Capillary -> Venule -> Vein

Blood leaves a capillary through a venule, a small vein. At that point, the blood is making its journey back towards the heart.
Microcirculation
A venule is a very small blood vessel. It drains a capillary bed and meets up with other venules which drain blood into larger vessels called veins.
Either a arteriole on the artery side or a venule on the vein side of the bed.
It's called blood vessel. it can be of following type viz Artery, Vein, Arteriole, Venule, Capillary.
Capillaries send blood to both arteries and veins.
artery- vein- capillary
