Explanation / Answer

25. Aldosterone is a steroid hormone which is produced by adrenal cortex that leads to increased sodium reabsorption(retention) and potassium secretion(loss in the urine).

26. Antidiuretic hormone is a peptide hormone secreted by the pituitary gland which leads to increased water reabsorption by the insertion of water channels or Aquaporins in the cell membrane.

27. Release of ADH and Aldosterone are decreased when a person is hydrated because the blood solutes decrease and so does the osmotic pressure. Therefore the pituitary gland is sent a signal that the osmotic pressure is low and there is a decrease in production of Aldosterone and ADH.

28. Normal blood has an osmolarity of 300 mOsm

29. Normal urine has an osmolarity of 600 mOsm

30. With dehydration urine osmolarity increases. This leads to the release of ADH which helps the kidneys to reabsorb water.
