Prolonged strenuous exercise usually leads to anincrease in lactic acid. Given your knowledge ofnormal circulation, explain why it is helpful tohave a cool-down period with mild exercise ratherthan total rest immediately after strenuousexercise

Suppose a pregnant woman with severe morning sickness has been vomitingsteadily for several days. How will her loss of stomach acid affect the pH of her body fluids? Explain.

The kidney has an unusually large demand for glutamine andglutamate. How does the metabolism of these compoundshelp maintain pH balance?

After eating an undercooked hamburger, a twenty-five-yearold male developed diarrhea due to infection with a strain of Escherichia coli that produces a shigatoxin. How would this affect his blood pH, urine pH, and respiratory rate?

Define abscisic acid

Three systems of the body help regulate acid/base balance - buffer system, respiratory system and renal system. Describe the renal response in a person experiencing metabolic alkalosis due to severe vomiting. Provide the general formula for pH control in acid/base regulation.

Concerning the reaction that is catalysed by carbonic anhydrase in red blood cells, briefly describe how the products of this reaction contribute to the buffering capacity of body fluids .

Metabolic alkalosis refers to a process whereupon decreased hydrogen ion, or increased bicarbonate, concentrations occur in the body, and the blood pH becomes too basic. Answer the following questions: How does the body regain its acid-base equilibria/balance? What happens when that balance does not happen? Will a buffer system still work under these conditions?

Glucose in the urine is referred to as _____________.
