Blood Buffer Composition
Date: Winter 2009 - 2010
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
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.
