Question

Quizplus · Accepted Answer

The kidneys play the primary role in maintaining acid-base balance through the regulation of hydrogen and bicarbonate ions in the blood. They can excrete or retain these ions based on the body's needs, resulting in a balanced pH level in the bloodstream. The other organ systems listed can contribute to acid-base balance in some way, but they are not the primary regulatory system. The kidneys play the primary role in maintaining acid-base balance through the regulation of bicarbonate ions and acid excretion. They can adjust the amount of bicarbonate that is reabsorbed or excreted to maintain the proper pH balance in the body. The lungs can also play a role by releasing or retaining carbon dioxide, but their impact is more limited than that of the kidneys. The skin and GI tract do not play a significant role in acid-base balance.
