Part C Now go to the Preventing Seasonal Flu with Vaccination page. Use the links on the page to construct one to two paragraphs in response to the following questions. Why do you think the flu vaccine is recommended every year? How does the vaccine affect the immune system? When is the best time to get a flu vaccine? Why? Is the vaccine effective? Who is and who is not recommended to receive a flu vaccine? Why do these recommendations exist? Why is it important for the CDC to update its flu vaccination recommendations each year?

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i.e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).
