carbonic anhydrase
The enzyme that converts carbon dioxide and water into carbonic acid
buffers
Chemicals that prevent sharp changes in pH when an acid or base is added to a solution

If a strong acid such as HCL were added to the buffer pair NaHCO3 and H2CO3, the NaHCO3 would become this
NaHCO3
If a strong base such as NaOH were added to the buffer pair NaHCO3 and H2CO3, the H2CO3 would become this.
distal tubule
The part of the nephron that is important in regulation of blood pH.
NaH2PO4
When Na2HPO4 is used by the kidney to remove hydrogen ions from the blood, the end product that leaves the body in the urine is?
NH4Cl
When ammonia is used by the kidney to remove hydrogen ions from the blood, the end product that leaves the body in the urine.
base
The kidney is more effective in pH regulation that the lung because it can remove this because the lung cannot.
alkalosis
The condition in which the blood pH is higher than normal.
acidosis
The condition in which the blood the blood pH is lower than normal.
