A venule is a very small vein in the microcirculation that allows blood to return from the capillary beds to drain into the venous system via increasingly larger veins. Post-capillary venules are the smallest of the veins with a diameter of between 10 and 30 micrometres (μm).
A venule is a small blood vessel in the microcirculation that allows deoxygenated blood to return from capillary beds to larger blood vessels called veins.
Venules are vessels which lie between capillaries and veins, thus connecting them together. They have extremely thin walls, similar to that of capillaries, which give them a misshapen or flattened appearance in a cross-sectional view.
Venules Definition: Small blood vessels in the microcirculation system that collect blood from capillaries and transport it to veins. Venules Function: Enable the return of deoxygenated blood to the heart, facilitate the movement of white blood cells, and assist in metabolic waste removal.
…organs and parts are called venules, and they unite to form veins, which return the blood to the heart. Capillaries are minute thin-walled vessels that connect the arterioles and venules; it is through the capillaries that nutrients and wastes are exchanged between the blood and body tissues.
Definition. Venules are small blood vessels that drain blood from capillaries into veins, facilitating the return of blood to the heart. They play a critical role in the circulatory system by aiding in the exchange of nutrients and waste between blood and tissues.
