Capillaries.
The venules are tiny blood vessels that return blood to the veins. Only 25 percent of a humans blood are contained in the venules.
A tiny arery is known as an arteriole. Venules are tiny veins.
Its venules
The blood vessels in between arteries and veins are the capillaries. But, they do not link them together, rather, they both have openings, through their capillaries, into the interstitial space which is the space between the cells of the tissues of the body.

The function of blood capillaries is to provide cellular, or tissue, respiration, provide nutrients and remove waste products. They are the tiny blood vessels that are between the venules and arterioles and the interstitial space between cells.

Arteries divide into smaller vessels called Arteriols. Arteriols subdivide into even smaller vessels called capillaries, where oxygen, nutrients, hormones are delivered to the tissues of the body. Waste products are also picked up by capillaries and delivered to venules which grow into larger vessels called veins. Veins deliver deoxygenated blood back to the heart.
Temperature receptors are located throughout the skin. There are tiny blood vessels, called capillaries, beneath the skin. Those vessels not only bring blood to the skin, they exchange heat. Because the skin is in contact with the environment, heat or cold can travel through it and affect the temperature of the capillaries. The blood in these vessels then travels through the body and transfers that temperature change to larger blood vessels, the venules and arterioles. The venules and arterioles become veins (which take blood to the heart) and arteries (which take blood away from the heart) and continue exchanging heat, which ultimately changes the core temperature of the body.
Why are nephrons surrounded by many tiny blood vessels
There are three types of blood vessels; arteries, veins, and capillaries. Capillaries are tiny blood vessels.
