- Which of the following statements is false regarding aging? a) Decreased ability to contribute to vitamin D synthesis, leading to Ca2 + deficiency and bone fractures. b) Numbers of glomeruli decrease and hence the ability to secrete and reabsorb. c) Gradually increasing size of the kidneys d) The ability to concentrate urine decreases and the kidneys respond to memories of ADH and aldosterone.arrow_forwardDuring a state of low blood volume and decreased extracellular sodium level (as in cardiac failure), which one of the following occurs? 1) B. Aldosterone is produced by the kidneys, leading to the release of renin, which increases kidney reabsorption of sodium. 2) D. Antidiuretic hormone produced by the kidneys stimulates the production of aldosterone by the adrenal gland, which increases reabsorption of sodium and water retention. 3) A. Renin is produced by the kidneys and is converted to angiotensin, which induces the secretion of aldosterone by the adrenal gland, which in turn increases reabsorption of sodium and retention of water. 4) C. Renin is produced by the adrenal glands, leading to vasoconstriction and production of antidiuretic hormone by the pituitary gland, which increases fluid volume by causing water retention. no references, just homeworkarrow_forwardSelect the best answer or answers from the choices given: Which of the following is/are true about ADH?
