Detailed explanation-1: -Venules are small blood vessels in the microcirculation that connect capillary beds to veins. Venules range from 8 to 100m in diameter and are formed when capillaries come together. Many venules unite to form a vein.
Detailed explanation-2: -Veins carry blood toward the heart. After blood passes through the capillaries, it enters the smallest veins, called venules. From the venules, it flows into progressively larger and larger veins until it reaches the heart.
Detailed explanation-3: -There are three sizes of veins, large, medium, and small. Smaller veins are called venules, and the smallest the post-capillary venules are microscopic that make up the veins of the microcirculation. Veins are often closer to the skin than arteries.
