Physiological Basis for Medical Advice
1. Kevin’s father has been advised by his physician to take an aspirin a day “to reduce his risk of heart attack.” What is the physiological basis for this advice?
2. Natalya is concerned because her feces are a chalky white color. Explain why this might occur. Why should Natalya consult her physician?
(Hint: You didn’t study what produces “chalky white” feces in this lesson. You DID, however, study what causes feces to be brown. Chalky white would be the absence of this color … hmmm, maybe Natalya has a problem within this process?)
3. How is clot overgrowth usually prevented? Name two conditoins that may lead to unnecessary (and undesirable) clot formation.
