Answer» Correct Answer - B The loop of henle has a key role in water conservation. Based on lengths of the loop of henle, there are two types of nephrons: (i) Cortical nephrons: they have short loops of henle which only just extend into the medulla which function most importantly when the suppy is normal to excessive, (ii) Juxtamedullary nephrons: they have long loops of Henle that extend deep into the medulla which function most importantly when water is in short supply. The lengths of loops of Henle and of the collecting ducts, and the general thickness of the medulla region of the kidneys, increase progressively in animals best adapted to the drier habitats. |
