The structures of the nephron that maintain the high solute concentration in the medullary region of the kidney are options (a) and (c)i.e, the Loop of Henle and Vasa recta.
The tiny or microscopic structural and functional component of the kidney is called a nephron. A renal corpuscle and a renal tubule make up its structure. A tuft of capillaries called a glomerulus and a cup-shaped structure called Bowman's capsule make up the renal corpuscle. From the capsule protrudes the renal tubule. Each nephron is made up of a renal corpuscle (glomerulus within Bowman's capsule), a proximal tubule (convoluted and straight components), an intermediate tubule (loop of Henle), a distal convoluted tubule, a connecting tubule, cortical, outer medullary, and inner medullary collecting ducts, as well as these additional components.
One of the two types of blood capillaries that emerge from the efferent arterioles of the nephron is the vasa recta. They are less numerous and surround the juxtamedullary nephrons' Henle loop. As a result, they exclusively develop in the kidney's medulla of birds and mammals, where they concentrate urine.
