The bicarbonate-carbonic acid buffer system
A blood test called an arterial blood gases (ABG) test analyzes the pH, oxygen (O2), and carbon dioxide (CO2) levels in an artery. The purpose of the test is to evaluate the patient's lungs' ability to eliminate carbon dioxide from the blood and transport oxygen into it.
The buffer between carbonic acid (H2C03) and bicarbonate (HCO3-) is essential for preserving the acid-base balance in the blood. Sodium bicarbonate (NaHCO3) serves as a weak base and H2CO3 as a weak acid.
Bicarbonate makes weak acids from strong acids, and strong bases from weak acids generate neutral solutions.
By controlling the generation of bicarbonate, the kidneys support the bicarbonate buffer system. The lungs help by controlling the amount of carbonic acid produced.

Explanation:
This excerpts is from the Native's son by Richard Wrights which depicts the oppressive effect racism of a black man, Bigger Thomas.
Bigger was a black boy who was employed as Mary's chauffeur. On that faithful day, he drove Mary (the only child and a very rich white girl who has far leftist leanings) and her boy friend Jan round the city. Mary was inebriated due to consumption of alcohol and was unconscious. On their arrival at home, Bigger carried her to her bedroom and could not avoid the temptation of kissing her. And suddenly, Mary's blind mother came into the room. As a result of his hatred and fear, Bigger accidentally killed Mary Dalton using a pillow to suffocate her to death.
Bigger’s attitude toward whites was a combination anger and powerful fear. His defense falls on deaf ears and was sentenced to death by electrocution.
