What is the primary function for the release of aldosterone and angiotensin ii?

CHF. These are secreted by the body intent on increasing intravascular volume. They can be an appropriate compensatory mechanism when volume is low, or they can aggravate hypertension and chf, when they become excessively secreted.

Which one causes more na and h2o reabsotbtion angiotensin II or aldosterone?

Both can. Increase sodium and water retention, but generally aldosterone is more active, present in larger amounts, and maintained at higher levels. I would be curious about what led to your asking this question. Read more...
Aldosterone. Aldosterone is powerful in causing na reabsorption. Ang ii is a powerful vasoconstrictor. Ang ii is converted from ang i by angiotensin converting enzyme (ace). Read more...
Read on: They are part of the same pathway. Angiotensin ii in the kidney leads to the release of aldosterone from the adrenal cortex. Angiotensin ii also causes sodium retention in the proximal tubule, but which is more potent? Good question. You'd have to do a rat experiment on isolated nephrons ex vivo. Maybe it's been done?

AII vs aldo and salt. Aldo causes more Na retention and water follows salt. But depends on circumstances. AII is major drive to aldo production so if AII high get same effect if you don't die form the severe HTN from excess AII. Both can be counteracted if you eat less salt. I am a specialist in the renin angiotensin aldosterone system and happy to consult with you. Read more...

If someone was to have low angiotensin II and low aldosterone would you expect to see a lower renin also?

Renin levels. If one has a low aldosterone and angiotensin ii, one would expect a high renin level. Renin leads to angiotensin i and ii synthesis. If those levels are low and the person is ambulatory, the person's renin would be expected to be high.

Aldosterone 161 pmol/l - renin/aldosterone ratio 5 - renin 11.4 ng/l - angiotensin II 8ng/l. I have postural orthostatic tachycarda. Why low angioten?

All connected. I am not an expert on this and you don't mention your lab standards so it is hard to say, but they are all connected to each other to regulate the volume of fluid and salt held or released by your kidney and there for your blood pressure. Too little salt then too little volume of blood and BP drops when you stand. Read more...

Why is my angiotensin II only 8 normal range 20-40ng/l? My aldosterone was 161 p/mol. I have dysautonomia and pots. I pee a lot when I drink.

Angiotensin II. A specific radioimmunoassay for angiotensin ii showed that normal concentration in arterial blood is 2·4±1·2 (s.D.) m?g./l00 ml.; venous level is consistently below this value, usually 50–75% of it. Definite rises in blood angiotensin ii were found in some patients with hypertension, both essential and secondary to renal disease. Extremely low levels observed anephric state and conn's syndrome.

I pee a lot of what I drink low normal aldosterone low angiotensin ii. Will florinef (fludrocortisone) help me retain more and pee less?

Think about this: If you urinate just 10 cc more than you take as food or drink per day, in 1 year, you'll be 3.6 liters drier and in 5 years, 20 liters behind! (not possible). No, your kidneys carefully balance your fluids. What low aldosterone and angiotensin control is your BP and your sodium ; potassium. Flurinef will raise your BP and help you retain sodium and excrete potassium. Read more...
