as a lover of the mola, I disagree with the conclusions Scout Burns draws, but give mad points for style and execution. 10/10 Facebook rant. Agree with Bob and other pelagic researchersâ¦ molas are awesome, fast, predators that given their numbers and chosen prey must play an integral role in the open ocean ecosystem.
1 Sodium ions are one of the dominant extracellular ions. 2  Aldosterone increases sodium reabsorption from the filtrate. 3  ADH increases water reabsorption from the nephron, and atrial natriuretic hormone increases sodium loss in the urine. 4  Aldosterone increases potassium secretion in the urine.
Because aldosterone increases sodium blood levels and increases blood pressure, we see that the secretion of aldosterone is triggered by decreased blood sodium levels or low blood pressure.Aldosterone also acts on the kidneys to increase the excretion of potassium.his can boost blood volume and blood pressure. Aldosterone is the main mineralocorticoid secreted by the adrenal cortex. When low blood pressure is detected by the kidneys, we see the start of the renin-angiotensin system, which is a hormonal cascade that leads to the production of angiotensin II.
