PTH and Calcium Flashcards
1
Q
What will acidic conditions (decreased pH) do to plasma Ca2+?
A
It will increase the amount of ionized Ca2+
2
Q
What will alkaline conditions (increased pH) do to plasma Ca2+?
A
It will decrease the amount of ionized Ca2+
3
Q
Why do acidic conditions raise the serum levels of free ionized Ca2+?
A
In acidic conditions there are more H+ bound to albumin, freeing up Ca2+ that would have been bound to albumin.
4
Q
Why do alkaline conditions lower the serum levels of free ionized Ca2+?
A
In alkaline conditions there are less H+, so more Ca2+ is bound to albumin.
