superior and inferior vena cava
They drain into small veins.
The blood in venules of the systemic circulation is deoxygenated. The blood in pulmonary venules is oxygenated.
The venules are tiny blood vessels that return blood to the veins. Only 25 percent of a humans blood are contained in the venules.
The frogÃ?s foot is compromised of thin skin making it ideal to view blood flow. The movement of blood into the capillary bed is monitored by the arterioles and the venules drain it away.
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.
Capillaries
Function- a venuole does the same job as a vein but is smaller than a vein. They are vessels that drain the deoxygenated blood from the capillaries and takes them to the veins which returns it to the heart. Structure- a venuole branches off the vein and is also linked to the capillries.
venules
A venule is a small vein. A vein always carries blood to the heart and usually carries oxygen poor blood. Since the circulatory system is circular, all of the vessels connect at some point. That happens in capillary beds, which are where venules (small veins) and arterioles (small arteries) meet. Arteries carry blood away from the heart and are usually oxygen rich. Venules fuse to form veins that bring the blood back to the heart where it can get oxygenated and deliver it to body tissues where the whole cycle starts again.

Venules
Renal vein It is not renal vein. It is venules. renal vein is only at one point of the body, were talking capillaries; which are all over the body.
Arteries feed into capillaries, the capillaries give oxygen and nutrients to every cell in the body and take toxins and CO2 from every cell in the body, from there the blood in the capillaries go into your veins (the blue blood vessels) which go to your heart.
