Blood vessel carrying the blood out of glomerulus is __________.

Each human kidney has about one million structural and functional units called nephrons. Each nephron is made up of 2 main parts: malphigian body and renal tubule. Malphigian body comprises a cup shaped Bowman's capsule and a network of blood capillaries (glomerulus). The renal artery, after entering the kidney, divides and redivides forming various afferent renal arterioles. This renal artery brings dirty blood containing waste substances. An afferent arteriole enters Bowman's capsule to form glomerulus. The efferent renal arteriole has narrower lumen than the afferent renal arteriole. Thereafter, an efferent renal arteriole leaves the glomerulus. The efferent renal arteriole breaks up into capillaries around the tubules. All the capillaries, in turn, unite to form renal venules and the latter together form the renal vein, which leaves the kidney. Vasa recta are the capillaries around this loop of Henle. The vasa recta help to retain reabsorbed ions and urea.
