14.These diuretics inhibit sodium reabsorption upstream of the principal cells, which meanis more sodium is delivered downstream to the principal cells.
15.Now, that calcium's still in the lumen, though, but parathyroid hormone also affects the distal convoluted tubule and increases calcium reabsorption.
18.At the same time, it stimulates production of calcitriol which promotes absorption of calcium in the small intestine, while also increases reabsorption in the kidney.
19.Lastly, parathyroid hormone increases calcium reabsorption and reduces the reabsorption of phosphate from the kidneys, so more phosphate is excreted through the urine.
20.T3 increases cardiac output, stimulates bone reabsorption thinning out the bones and then activates the sympathetic nervous system, the part of the nervous system responsible for our fight-or-flight response.
