What are the buffer systems in your body that keep you alive activity 51?

There are three primary systems in the body that act as a buffer, in order to help maintain pH stability. The first is known as the phosphate buffer, which neutralizes excess hydroxide ions as they enter cellular fluid. The second is called the protein buffer, and maintains acidity in the body. The hemoglobin in blood, which binds to acids in the bloodstream, is one such example of this system. The third system is called the carbonic acid bicarbonate buffer, which neutralizes the acids generated by various metabolic processes, such as digestion and respiration.
