With Negative Pressure Breathing,the Muscles That Move the Ribs and Diaphragm

question 15

Multiple Choice

With negative pressure breathing,the muscles that move the ribs and diaphragm are distant from the absorptive alveolar surfaces.What difficulty(ies) could occur if the muscles were around each alveolus and had to expand each alveolus to suck in air?

• A)Muscle tissue would get in the way of absorption of gases across the air-to-capillary border.
• B)Interspersed muscle tissue would take up much space and the lung-muscle volume would have to be much larger.
• C)Since muscle cells only contract and relax,it would be difficult for a few cells to cause alveolar expansion.
• D)Adding a third tissue to the intimate alveolar-capillary complex would increase the problems with disorders and diseases.
• E)All of the choices are correct.
