Henry is a 65-year-old man who was admitted to the emergency room after a fall. A radiograph confirmed that he had fractured the
proximal part of his arm bone (surgical neck of the humerus). The radiograph also revealed that his bone matrix was not as dense as it should be for a man his age. A test for blood Ca2 was normal. On questioning, Henry confessed that he is a junk food addict who eats few vegetables and never consumes dairy products. In addition, Henry never exercises and seldom goes outdoors except at night. Use your knowledge of bone physiology and process figures from the textbook to answer the following questions. 1.Why is Henry more likely to break a bone than are most men his age

The smallest bronchioles end in tiny air sacs, called alveoli. They inflate when a person inhales and deflate when a person exhales. During gas exchange oxygen moves from the lungs to the bloodstream.
