<h3>What is
blood pH?</h3>
Blood pH can be defined as a measure of the molar concentration of hydrogen ions that are present in the blood of a living organism, with respect to its acidity, neutrality or alkanlity (basicity).
In response to a notification of a <u>decrease</u> in blood pH by the nervous system, the brain would send signals (impulses) to the external intercostal muscles and the diaphragm through its respiratory center, so as to help the living organism increase its breathing rate and the volume of its lungs during inhalation.
