Solved in 3 steps
- Harry ate a late meal at a cheap diner on the way home from work.A couple of hours later, he vomited three times, and then he consumed several packages of an antacid (mostly NaHCO3) over thenext several hours. By the evening of the next day, he was feelingbetter. During this ordeal, his blood pH did not deviate significantly.Select the mechanism(s) that helped maintain Harry’s pH within anormal range.(1) increased respiratory rate(2) increased H+ secretion by the renal tubule(3) decreased respiratory rate(4) decreased H+ secretion by the renal tubulea. 1 b. 2 c. 1,2 d. 3 e. 3,4Why are the bicarbonate and phosphate buffers the main buffers in the blood and cells, respectively, and not vice versa?if pH level of solution changes from pH 5 to pH 2, how much acidity increased in that solution and why?
- looking at ABG's, if ph is normal, Bicarb is alkaline, and paCO2 is acidic...what do you say about it? its not clearly in any of the 4 states, partially compensated, etc pH 7.37 HCO3 45 PaCO2 66.What is the effect of adding a small amount of a strong acid or strong base to the acidity of a buffer? How would this compare to an unbuffered solution of the same acidity?What is the function of the buffer phosphate in the human body?
- Why does the addition of acid have so much less of an effect on the pH of blood than it does on the pH of water?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.In your own words, explain the Mechanism of Buffer Action.
