Summary Introduction

To compare:

Oxygen and carbon dioxide transport in the blood

Introduction:

Blood receives oxygen from air in the lungs and provides it to body cells at the same time blood absorbs carbon dioxide from cells and releases it into lungs. The exchange of gases occurs because the concentration gradient favors it.

Summary Introduction

To determine:

The source and destination of oxygen and carbon dioxide and also determine the physiological process that makes gas exchange necessary.

Introduction:

The exchange of gases occurs because the concentration gradient favors it. In lungs the oxygen concentration is high and carbon dioxide is low, whereas in cells the concentration of oxygen is low and carbon dioxide is high.

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
