Question

What is the most rapid defense against changes in blood pH?

1) respiratory compensation
2) buffering of hydrogen ions
3) renal compensation
4) cardiac compensation
5) hepatic compensation

Answer 1

Respiratory compensation is the most rapid defense against changes in blood pH.

Step-by-step explanation:

The most rapid defense against changes in blood pH is respiratory compensation. When there is an imbalance in blood pH, the respiratory system can adjust the respiratory rate to alter the levels of carbon dioxide (CO₂) in the blood. This adjustment occurs within minutes, making respiratory compensation a quick response to maintain blood pH.
