What is the principal regulator of calcium balance?
|
PTH (Parathyroid Hormone)
|
|
| 2 |
Parathyroid Hormone (PTH) maintains plasma Ca by stimulating reabsorption in the _________
|
Distal tubule
|
|
| 3 |
T or F: Kidney is output site for Ca
|
True
|
|
| 4 |
Input site for calcium into body?
|
GI
|
|
| 5 |
What stimulates calcium absorption into the GI?
|
calcitrol
|
|
| 6 |
What stimulates the synthesis of calcitrol aka 125 dihydroxy vitamin k?
|
PTH parathryoid hormone
|
|
| 7 |
How does PTH (secreted from parathyroid) regulate ca?
|
reabsorption in kidney and reduction in urine; absorption in GI; bone resorption
|
|
| 8 |
What regulates plasma phosphate?
|
parathyroid hormone (PTH)...calcium too
|
|
| 9 |
Where is phosphate filtered?
|
glomerulous
|
|
| 10 |
Where is phosphate reabsorbed?
|
PT and DT
|
|
| 11 |
Are phosphate and calcium secreted in the tubules?
|
no
|
|
| 12 |
Does PTH inhibit or stimulate pho4 absorption in pt?
|
inhibit
|
|
| 13 |
When PTH increases, what happens to Ca reabsorption? increases. PO4 reabsorption?
|
calcium increases; pho4 decreases
|
|
| 14 |
phospate reabsorption is most dependent on?
|
what's happening with calcium
|
|
| 15 |
Where is K filtered?
|
glomerulus
