Question

BIOL n / Human A&P; II Exam s e page g of 62. "Hunger receptors" are located in the hypothalamus. (A) true (B) false Part V- Matching Match the numbered items on the left to the nephron structure with which each is most closely linked, either anatomically or physiologically Each letter may be used once, more than once, or not at all. (A) Bowman's capsule (B) (C) (D) (E) 63. ADH has its greatest effect here. Distal convoluted tubule Loop of Henle Proximal convoluted tubule More than one of these answers is correct 64. Aldosterone most influences sodium reabsorption here. 65. Afferent arteriole 66. Aquaporins are formed here to reabsorb water 67. Efferent arteriole 68. Filtration occurs here None of these answers is correct The primary difference between cortical nephrons and juxtamedullary nephrons is in the length of this structure Glomerulus Peritubular capillaries Portions of this structure are impermeable to water Renal corpuscle This structure, from many nephrons, forms the renal pyramid Tubular reabsorption occurs here Tubular secretion occurs here The highest osmolarities in the body occur here The maximum that we can concentrate our urine depends primarily on this structure's length. 69. (AE) 70. 71. 72. 73. 74· 75. 76. 77. 78. The next four questions concerns acid-base balance. Make use of the Davenport nomogram shown on page 2 as you answer these questions. Select the best choice among each of the lettered statements to complete each of the numbered statements. Part VI-Multiple Choice Shelly has not been feeling well lately.
