Textbook Question
Chapter 15, Problem 27RQ
The following figure is a schematic representation of the systemic circulation. Use it to help answer the following questions. (CO = cardiac output, MAP = mean arterial pressure).
- a. If resistance in vessels 1 and 2 increases because of the presence of local paracrine signals but cardiac output is unchanged, what happens to MAP? What happens to flow through vessels 1 and 2? Through vessels 3 and 4?
- b. Homeostatic compensation occurs within seconds. Draw a reflex map to explain the compensation (stimulus, receptor, and so on).
- c. When vessel 1 constricts, what happens to the filtration pressure in the capillaries downstream from that arteriole?

Read one the attached article and explore the Human Development Index
(https://hdr.undp.org/data-center/human-development-index#/indicies/HDI).
In your opinion, is the Human Development Index a good measure of the well-
being of the people of a nation? Are the items measured in the HDI valid and
relevant in the modern global economy? How are they related to the political
economy of a nation?
The attached articles propose some alternative measures of well-being. In your
opinion, are there other measures of well-being that might be better alternatives
to the items in the current HDI?
A patient visits her doctor with symptoms typical of a bladder infection. She is immediately prescribed an 800 mgdose of antibiotic (bioavailability = 1/2, t½ = 12 h). The corresponding plasma concentration of drug is found to be 96 micrograms/ml. What is the volume of distribution of this drug? Please round to the nearest liter.

After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites.
