Observe the parts of a nephron and the associated blood vessels. Label: Bowman's capsule, proximal convoluted tubule, descending loop of Henle, ascending loop of Henle, distal convoluted tubule, renal artery, afferent arteriole, glomerulus, efferent arteriole, peritubular capillaries, vasa recta, renal vein. Arrange the following parts of a nephron in the correct sequence: Bowman's capsule, proximal convoluted tubule, descending loop of Henle, ascending loop of Henle, distal convoluted tubule.
