Explanation The countercurrent circulations help to exchange the dissolved substance by causing the movement of one of the solutes in one direction and other in the opposite direction. To maximize the concentration of oxygen in the fluids, the fishes perform countercurrent circulation through their gills. During this, the oxygen from the water moves inside the body of the fish. The resulting exchange results in the movement of carbon dioxide out of the body into the surrounding water...

Chapter 47, Problem 2DA

Summary Introduction

To determine: The countercurrent exchange system and the site where the most oxygen diffuse from water into the blood.

Introduction: Countercurrent circulation helps in exchanging dissolved substances. Therefore, to maximize the concentration of oxygen in the blood, the fishes eliminate carbon dioxide in the opposite direction that is opposite to the movement of oxygen and gets rid of carbon dioxide at the same time.

a. What percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent. b. What will happen to elimination of the drug in the previous question if the system is saturated? explain and show any math involved

If you wanted to reduce the difference between peak and trough levels that occur with repeated administration of a drug, how would you adjust the dose and dose interval without changing the plateau concentration (plateau is the average of peak and trough levels)? Select your answers for both dose and interval. Hint: It may be helpful to think about this problem using an example such as food. How would you eat if you wanted to maintain very steady hunger/satiety levels without changing your total caloric intake? Options: A. Dose; Increase dose B. Dose; Decrease dose C. Dose; Do not change dose D. Interval; Increase the interval between doses (give the drug less frequently) E. Interval; Decrease the interval between doses (give the drug more frequently) F. Interval; Do not change the interval
