Exam 20: Acid-Base Balance

Arterial blood has a pH of 7.45.Venous blood has a pH of 7.35.This means that arterial blood has fewer hydrogen ions than arterial blood.

Match each term with its definition or description. -Scale that measures the hydrogen ion concentration in a solution

If the sodium bicarbonate-carbonic acid buffer pair was to buffer a solution of NaOH,water would be an end product.

Explain why compensation is a clinically important concept.

Pure water with a pH of 7.0 would have neither hydrogen nor hydroxide ions.

When the carbonic acid-sodium bicarbonate buffer pair buffers a base

Match each term with its definition or description. -Enzyme that combines water and carbon dioxide to form carbonic acid

Match each term with its definition or description. -A condition that results from a carbonic acid deficit

When the carbonic acid-sodium bicarbonate buffer pair buffers an acid

Water turns carbon dioxide into carbonic anhydrase.

Match each term with its definition or description. -A general term that describes a condition of high blood pH

To raise the pH of the blood,the kidneys lower the pH of the urine.

A decrease in respiration rate

The slightly lower pH of venous blood compared to arterial blood is caused by

When the kidney secretes hydrogen ions

A solution with a pH of 9.0 has

If the sodium bicarbonate-carbonic acid buffer pair was to buffer a solution of HCl,sodium chloride would be produced.

Carbonic acid excess can lead to respiratory alkalosis.

Explain the reaction of the carbonic acid-sodium bicarbonate buffer pair to an increase in hydrogen ions.

Hyperventilation can cause acidosis.
