2. (10 pts) Reabsorption and secretion are primary functions of the nephron. 1) In the first row fill in the cell type(s) found at that region of the nephron. 2) In the second group of rows fill in the chart with the terms secretion, reabsorption or either to indicate the process occurring at that part of the nephron and collecting duct. 3) In the final group of rows indicate where the hormones ADH, aldosterone and parathyroid hormone have their affects by listing the roles of the hormones in reabsorption or secretion of Ca2+, Na+ ,K+, water and urea, in the column corresponding to the region of the kidney in which they function. (you will not use all the columns.)
