describe 2ndary and tertiary hyperparathyroidism
2ndary - due to renal disease, cannot excrete phosphate and it is elevated - stimulates PTH to secrete.

tertiary - since PTH mainly responds to serum Phos, continuously increasing PTH, continually increasing phos leads to chronic PTH secretion, and glandular hypertrophy, leading to autonomous hypersescretion of PTH. even after calcium/phos levels are corrected, PTH stays high
