Question

, A curious but confused patient has been diagnosed with metabolic acidosis and wants to understand what is going on. He asks you to explain how acid-base balance works in the body. Be sure to describe in detail the roles played by the respiratory, urinary, circulatory, and digestive systems. Be sure to cover all the most important terms and to explain them in your own words. Remember you are explaining this to someone who doesn’t understand it so don’t leave anything out, but you can assume they have a very good basic understanding of the human body.

Answer 1

The normal pH of our blood is 7.35-7.45 that is it maintain this oh for the optimum working condition of body.

Our body maintain the pH of our blood by the maintaince of H+ ,HCO3,. AND CO2 values in blood . The balances between them provide a hemostasis

In the respiratory system when the pH decrease in blood hyperventilation occur leading to the excretion of co2 from blood there by compensate for the decrease in blood pH . When the pH increase it will be alkaline so the respiratory rate decreases and lead to the retention of co2 increasing the pH

The urinary system plays a major role in the function of acid base balance as when pH increase it will lead to excretion of HCO3 from Body in exchange for the H+ SO THAT pH REDUCED. In case if reduction in pH it will lead to a retention if HCO3 and excretion of H+ from body .

The circulatory system has a main function to keep the cell and ECF in the pH range and is maintained by the excretion and retention of specific substance in blood .

The digestive system absorb specific substance from stomach and maintain the lh of blood

Proteins buffer is one of the method by which the pH is maintain

The patient is having metabolic acidosis and is causing an increase in H+ absorption and excretion of HCO3 . So here respiratory compensation will come . This will cause the hyperventilation and lead to decrease in pH by reducing co2
