Acid-Base Balance and Body Fluids Quiz

Kidneys regulate acid-base balance through filtration and secretion.

Metabolic alkalosis is associated with conditions such as excessive vomiting, leading to loss of acid.

Arterial blood pH typically ranges between 7.35 and 7.45.

Carbonic acid is a volatile acid eliminated by the lungs through expiration.

Phosphoric acid is a non-volatile acid that contributes to the body's acid load.

Respiratory acidosis refers to an accumulation of carbon dioxide in the blood, leading to acidification.

Potassium ion, as a weak acid, can influence intracellular pH levels.

Normal serum bicarbonate concentration ranges between 22 and 26 milliequivalents per liter (mEq/L).

Respiratory alkalosis can occur due to hyperventilation, leading to decreased carbon dioxide levels.

Bicarbonate ions primarily neutralize acids to maintain pH balance.

Ketoacidosis involves metabolic acidosis with rapid breathing due to elevated ketone levels.

The phosphate buffer system is a common buffer system in extracellular fluid.

The renin-angiotensin-aldosterone system regulates hydrogen ion secretion to maintain acid-base balance.

Carbonic anhydrase catalyzes the formation of carbonic acid from carbon dioxide and water.

Emphysema reduces the ability to exhale carbon dioxide, resulting in respiratory acidosis.

Prolonged metabolic acidosis can lead to elevated potassium levels, known as hyperkalemia.
