Buffers Resist Changes in pH
A buffer solution has at least two components: a compound to neutralize any incoming base and a compound to neutralize any incoming acid. This video lesson shows how buffering systems work. Duration: 6:22.

Buffers Resist pH Changes (Textbook)
Buffering Systems in Our Bodies
This video lesson starts by noting how it is that buffer systems only resist changes in pH. Their pH changes upon the addition of an acid or base, but not so drastically. Then there is a focus on the human buffering system of breathing. Duration: 5:07.
