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

H2CO3

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.

20

In order for the buffer pair to function correctly, the concentration of NaHCO3 must be this many times greater than the concentration of H2CO3.

H2CO3

Respiratory disturbances usually have an effect on this part of the buffer pair.

alkalosis

Severe vomiting is a metabolic disturbance that can cause metabolic _________________.
