Answer:

Because they can moderate gross changes in solution #pH#.

Explanation:

A buffer is a mixture of a weak acid, and its conjugate base in appreciable proportions. The buffer acts to moderate gross changes in solution #pH#.

Given the link, a buffer will tend maintain #pH# at or about the #pK_a# of the original acid used. Biological systems are extensively buffered.
