Question:
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?



Replies:
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.
