Stephania measured the volume of air breathed in and out of her lungs while she was training a. During exercise, Stephania breathed more air in and out of her lungs than before exercise. How much MORE air did she breathe in with each breath during exercise? ________________________________________________________________________________ b. Explain why Stephania needed to breathe in more air during exercise. ________________________________________________________________________________ c. As Stephania exercised, the volume of air breathed in and out increased. Name ONE other way how Stephania’s breathing changed during exercise. ________________________________________________________________________________ e. Explain how the breathing system is adapted to provide the lungs with clean air. ________________________________________________________________________________ f. Describe the role of the rib cage during breathing in. _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ g. Cigarette smoking affects the respiratory system, making it less efficient. Bronchioles lose elasticity and are unable to withstand the pressure in the alveoli causing them to rupture and leading to smoking-induced emphysema.
