Textbook Question
Chapter 47, Problem 1A
When you take a deep breath, your stomach moves out because
a. swallowing air increases the volume of the thoracic cavity.
b. your stomach shouldn’t move out when you take a deep breath because you want the volume of your chest cavity to increase, not your abdominal cavity.
c. contracting your abdominal muscles pushes your stomach out, generating negative pressure in your lungs.
d. when your diaphragm contracts, it moves down, pressing your abdominal cavity out.
