During a marathon race, a runner's blood flow increases to 13.0 times her resting rate. Her blood's viscosity has dropped to 85.0% of its normal value, and the blood pressure difference across the circulatory system has increased by 50.0%. By what factor has the average radii of her blood vessels increased?

Human Physiology! Please help.
Case Study: Mrs. Nguyen has high blood pressure. Her physician puts her on a medication that increases her urine flow rate (a diuretic) to help reduce her blood pressure. A side effect of this medication is that her plasma (ECF)K concentration drops from 4mM to 2.5 mM. 1. Using just the values for Na" and K' and assuming that her neurons are 25 times more permeable to potassium than to sodium, what is her neuron membrane...

While walking to work, Mio has a sudden onset of dizziness and
feels faint. In addition, she experiences diaphoresis (excessive
sweating) and palpitations (rapid, fluttering heart). When she
arrives at her office, her concerned colleagues call an
ambulance.
In the emergency department, the nurse and doctor make the
following notes in Mio’s record:
55-year-old female, blood pressure = 162/110 mm Hg, on
metoprolol, furosemide, propafenone.
Blood pressure dropped upon standing to 102/65 mmHg, and
palpitations were observed.
After receiving a...
