QUESTION Which compensatory mechanism of the renal system helps decrease acidosis in the body? ANSWER Decrease in the production of ammonia Conservation of $HCO_3^-$ by the resorption of bicarbonate Retention of hydrogen to keep it in the body Excretion of $HCO_3^-$ to rid the body of bicarbonate I DON'T KNOW YET

Which of the following events would occur after acidosis? (That is, what would the body do to "fix the problem" and restore homeostasis?) Question 3 options: - Chemical buffer systems (bicarbonate, phosphate, protein, etc.) would absorb hydrogen ions. - Increased renal reabsorption of hydrogen ions and increased renal excretion of bicarbonate. - Respiratory rate would decrease. - Increased renal excretion of hydrogen ions and increased renal reabsorption/generation of bicarbonate. - Chemical buffer systems (bicarbonate, phosphate, protein, etc.) would release hydrogen ions. - Respiratory rate would increase.

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
