Hello there,i have a question pleas help me and it is,what is the definition of buffer in blood and how dose buffer works in blood chemically?

One of the buffers in blood is the H2CO3/HCO3- system. A buffer system is a combination of a weak acid and a weak base that can coexist together in the same solution. It is called a buffer because it buffers against changes in pH. When acid is added to the system, it reacts with the weak base and converts it to a weak acid. When base is added, it reacts with the weak acid and converts it to the weak base.
