What is the mechanism of marrow cavity enlargement in a long bone?
A) There is no mechanism; once formed, the marrow cavity does not change in size. B) Blood vessels entering the marrow cavity enlarge it by eroding away the inner surface of the bone. C) The bone marrow cavity only increases in length, as the epiphyseal plates move apart. D) As bone matrix is added to the external surface, osteoclasts remove matrix in the center of the bone to enlarge the cavity. E) None of the answers are correct.
Which of the following is true of the pulmonary pressures?
A. Because of pneumothorax, intrapleural pressure equilibrates with atmospheric pressure. Without the positive force of alveolar pressure pushing the lung outward, the lung collapses due to elastic recoil forces. B. Intrapleural pressure is always positive so that the pleural membranes remain in contact. C. An increase in transpulmonary pressure creates a larger collapsing pressure across the lungs, which is accompanied by the contraction of the lungs (alveoli). D. The difference between intra-alveolar pressure and atmospheric pressure is the pressure gradient that drives ventilation.
