Essentials of Anatomy and Physiology

1. Men tend to be more watery than women. The rea-
   son has to do with two tissues, one of which is more

   are usually present in different proportions in men
   and women? Explain your answer.


2. Mrs. T, age 82, tells her visiting nurse that she has
   trouble walking around her house because her feet
   and ankles are swollen. The nurse makes a doctor’s
   appointment for Mrs. T, and says the problem may
   be her heart. Explain.


3. Ms. H, age 18, is on a diet that advises eight 8-

ounce glasses of water a day. Ms. H thinks that if

eight glasses are good, perhaps 12 glasses would be

better, because “water is good for you.” What can

you tell her? Is water always good?

4. Mr. C has what he calls “acid indigestion,” and
   takes chewable tablets to try to relieve it. He admits
   that the fruit flavors of the tablets often have him
   “popping them like candy” all day. He is visiting his
   doctor because he says his muscles feel “jumpy.”
   What would you expect to find for blood pH, res-
   pirations per minute, and urine pH? Explain your
