Exam 44: Acid Base Balance

If the pH of the blood were 7.23, it would be

Which of the following is considered a powerful physiological buffering system of the body?

The metabolism of ribonucleotides increases the hydrogen ion concentration of intracellular fluid.

Prolonged hyperventilation tends to:

On the pH scale, as the value moves from 14 toward 7, the concentration of hydroxide ions increases.

Why does arterial blood have a lower hydrogen ion concentration than venous blood?

Which of the following is most basic?

Explain the pH scale

The blood in the pulmonary artery has a lower pH than the blood in the aorta.

Toxic accumulation of acidic ketone bodies is a common complication of untreated:

The linkage between the hydrogen and potassium ions in the kidney can cause a drop in blood potassium when large amounts of hydrogen ion need to be excreted.

If a strong acid were added to the phosphate buffer pair, the amount of Na₂HPO₄ in the solution would increase.

Stomach acid is the most alkaline substance in the body.

Carbonic anhydrase is an enzyme necessary for the formation of carbonic acid in the kidney tubules.

The physiological buffers serve as a secondary defense against harmful shifts in the pH of body fluids.

Ammonia excretion causes the body to retain sodium ions.

The compensatory mechanisms that respond to acidosis may lead to hyperkalemia and cause heart blockage or death.

Which of these is not an acid-forming element?

Match each term with it corresponding definition. -Carbonic acid excess caused by conditions such as pneumonia or emphysema

A buffer would prevent any lowering of pH if a strong acid were added to a solution.
