Detailed explanation-1: -The pulmonary system adjusts pH using carbon dioxide; upon expiration, carbon dioxide is projected into the environment. Due to carbon dioxide forming carbonic acid in the body when combining with water, the amount of carbon dioxide expired can cause pH to increase or decrease.
Detailed explanation-2: -The kidneys have two main ways to maintain acid-base balance-their cells reabsorb bicarbonate HCO3− from the urine back to the blood and they secrete hydrogen H+ ions into the urine. By adjusting the amounts reabsorbed and secreted, they balance the bloodstream’s pH.
Detailed explanation-3: -By increasing the respiratory rate, we excrete more carbon dioxide, which is in equilibrium with carbonic acid. Breathing more deeply and quickly can move the blood pH toward the alkaline side. This usually happens without our being aware of it.
