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.
In the kidney, parathyroid hormone (PTH) blocks reabsorption of phosphate in the proximal tubule while promoting calcium reabsorption in the ascending loop of Henle, distal tubule, and collecting tubule. Parathyroid hormone (PTH) promotes absorption of calcium from the bone in 2 ways. The rapid phase brings about a rise in serum calcium within minutes and appears to occur at the level of the osteoblasts and osteocytes.
