List the three major chemical buffering systems in the body: 1. 2. 3. Which chemical buffering system is most important in extracellular fluids? Overall, metabolic activities tend to produce more acids than bases. Buffers provide temporary storage of H+ ions and provide short-term pH stability. Respiratory rate and renal physiology adapt to most prolonged changes in H+ production to maintain normal plasma pH. Acid-Base disorders can be due to metabolic or respiratory causes. Acid-base disorders due to an imbalance between CO2 generation and CO2 elimination are considered to be acid-base disorders. All other acid-base disorders are attributed to causes. Plasma pH varies with PCO2. Decreased minute ventilation or impaired gas exchange leads to a/n (loss/accumulation) of CO2 and H+ ions, which leads to an (increase/decrease) in pH. (Use arrows to indicate the direction of change for each indicated component of the following relationship.) _CO2 + H2O <-> _H2CO3 <-> _HCO3- + _H+; _pH This acid-base disorder would be categorized as

2. Among the most important pH buffer systems in humans is the bicarbonate buffer, which keeps the blood at a remarkably precise 7.42 pH. The bicarbonate buffer system uses a series of important compounds and enzymes to make the system function. The activity of this buffer system is mainly controlled by the renal and respiratory systems. The renal system excretes bicarbonate in the urine, while the respiratory system "blows off" carbon dioxide as needed. By balancing these two systems as needed, blood pH is maintained in such a narrow range. A patient undergoes a procedure in a hospital, and begins to reabsorb large quantities of bicarbonate from the kidneys. In the above reaction _________. a. CO2 production will decrease, while carbonic acid concentration builds up b. CO2 quickly builds up c. the equilibrium is shifted toward CO2 d. the equilibrium is shifted toward bicarbonate
