Kidneys Conserve Or Excrete Bicarbonatw Ions Depending On Plasma H+ Flashcards
0
Q
During acidosis
A
More H leave the blood by tubular secretion by type A intercalated cells
-these ions will be excreted from the body, removing the source of acidity in the blood
1
Q
Every time a H is tubularly secreted
A
A bicarbonate ion is reabsorbed (enters the peritubular capillariesh
-these two processes are coupled
2
Q
The reabsorption of bicarbonate ions
A
Also reduces the H level in the blood by buffering the free H and removing them from the solution
3
Q
The opposite responses occur during
A
Alkalosis
-type B intercalated cells
4
Q
The kidneys also secrete
A
Ammonia during acidosis to buffer secreted H
