| Source of aldosterone | Adrenal cortex and zona glomerulosa |
| Action(s) of aldosterone | Renal sodium retention with potassium and proton wasting |
| Signal(s) to release aldosterone | Adrenocorticotropic hormone (ACTH) |
| Effect of sodium retention by aldosterone | Volume expansion & increased blood pressure |
| Source of cortisol | Adrenal cortex |
| Action(s) of cortisol | Mediate blood glucose level |
| Signal(s) to release cortisol | Adrenocorticotropic hormone (ACTH) & corticotropin-releasing factor (CRF) |
| Less cortisol production during this time | Night |
| More cortisol production during this time | Morning |
| Source of angiotensinogen | Liver |
| Product of angiotensinogen conversion | Angiotensin I |
| Converter of angiotensinogen to product | Renin |
| Product of angiotensin I conversion | Angiotensin II |
| Converter of angiotensin I to product | Angiotensin Converting Enzyme (ACE) |
| Organ that produces angiotensin converting enzyme | Lung |
| Action(s) of angiotensin II | Vasoconstriction & aldosterone release |
| Source of renin | Juxtaglomerular cells of kidney |
| Signal(s) to release renin | High potassium; low sodium; decreased afferent renal arteriole pressure |
| Inhibitor(s) of renin release | Low potassium |
| Action of renin | Converts angiotensinogen to angiotensin I |
| Source of vasopressin | Neurohypophysis (posterior pituitary) |
| Signal(s) to release vasopressin | Increased blood osmolarity; pain; vascular stretch feedback |
| Inhibitor(s) of vasopressin release | Hypo-osmolarity |
| Action(s) of vasopressin | vasoconstriction; free-water retention by renal tubules |
| Source of calcitriol | Kidney |
| Action(s) of calcitriol | Elevate blood calcium by activating osteoclasts and elevating calcium binding protein in the gut |
| Source of calcitonin | Thyroid parafollicular (C) cells |
| Signal(s) to release calcitonin | Low blood calcium |
| Inhibitor(s) of calcitonin release | High blood calcium |
| Action(s) of calcitonin | Decrease blood calcium by inhibiting osteoclasts; Causes phosphate wasting by kidney |
