1. Antidiuretic hormone and the mineralcorticoids

7. Pathway by which ADH secretion is lowered and water exrection raised when excess water is ingested

10. Pathway by which ADH secretion and tubular permeability to water is increased when plasma volume decreases

12. Hypothalamus, posterior pituitary and ADH secretion– connection with baroreceptors

15. Osmotic and hemodynamic control of ADH secretion– changes in osmolality; changes in blood volume or pressure; interactions between osmolar and volume/pressure stimuli on ADH secretion.

20. Inputs reflexly controlling thirst.

22. Pathways by which sodium and water excretion are decreased in response to severe sweating.

24. Cross section through the adrenal gland– cortex and medulla salt sugar sex

29. Aldosterone synthesis in the adrenal zona glomerulosa

31. Regulation of aldosterone secretion: Activation of renin-angiotensin system in response to hypovolemia is predominant stimulus for aldosterone synthesis.

34. Components of renin-angiotensin-aldosterone system

40. Model for basic renal handling of potassium. Net absorption occurs in the proximal portions of the nephron and net secretion in the more distal portions of the nephron.

41. Action of aldosterone on the renal tubule. Sodium reabsorption from tubular urine into the tubular cells is stimulated. At the same time, potassium secretion from the tubular cell into urine is increased. Na + /K + -ATPase, and Na + channels work together to increase volume and pressure, and decrease K + .

44. Pathway by which an increased potassium intake induces greater potassium excretion mediated by aldosterone

45. Pathway by which aldosterone sercretion and tubular sodium reabsorption is increased when plasma volume is decreased

47. Cortisol is at 1000 fold higher concentrations than aldosterone

49. Summary of aldosterone system
