venule(veins)
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.
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.
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.

The blood vessels that are involved for supplying and draining blood from the small intestine are called the superior mesenteric. The blood vessels that supply and drain the large intestines are called the inferior mesenteric.
There are no vessels that drain the right atrium, except, perhaps the coronary veins. The right atrium moves blood through the tricuspid valve into the right ventricle of the heart.

Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
Lymph is interstitial fluid that drains from the blood vessels and goes into the interstital space. Lymph retruns to the blood stream via the lymphatic vessels that drain into the subclavian vein.
