In order for a person to breathe, gas exchange is needed to have an oxygen to breathe and to regulate the blood flow. To do this, the lungs is needed and with the help of their components namely the aveolar sacs, which enables to fill the air in the lungs, resulting to or producing vesicular breathing.

How can amino acids be use to maintain the blood pH?

Answer:

See the explanation below. Thanks!

Explanation:

The structure of an amino acid allows it to act as both an acid and a base. An amino acid has this ability because at a certain $pH$ value (different for each amino acid) nearly all the amino acid molecules exist as zwitter-ions. If acid is added to a solution containing the zwitter-ion, the carboxylate group captures a hydrogen ( $H^+$ ) ion, and the amino acid becomes positively charged. If base is added, ion removal of the $H^+$ ion from the amino group of the zwitter-ion produces a negatively charged amino acid. In both circumstances, the amino acid acts to maintain the pH of the system—that is, to remove the added acid $(H^+)$ or base $(OH^-)$ from solution.
