ANATOMY

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 respiratory tract can adjust the blood pH upward in minutes by exhaling CO2 from the body. The renal system can also adjust blood pH through the excretion of hydrogen ions (H+) and the conservation of bicarbonate, but this process takes hours to days to have an effect.

Detailed explanation-3: -Sodium bicarbonate, or baking soda, is often given to people with certain types of metabolic acidosis. The chemical compound that’s often used to treat heartburn by neutralizing stomach acid. When used to treat metabolic acidosis, it can help make your body’s fluids more alkaline, or raise the pH of your blood.

Detailed explanation-4: -Role of the kidneys The kidneys are able to affect blood pH by excreting excess acids or bases.
