Question

Quizplus · Accepted Answer

The regulation of blood pH is an example of a negative feedback loop. When blood pH decreases (becomes more acidic), the body responds by increasing the amount of bicarbonate ions in the blood, which helps neutralize the acid. This process continues until the blood pH returns to its normal range, at which point the body stops producing more bicarbonate ions. This is an example of a negative feedback loop because the response works to counteract the initial change and return the system to its original state, rather than amplifying the change like in a positive feedback loop.
