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.

Definitions:

Proportion of Successes

It is the fraction of successes in a series of Bernoulli trials, representing the number of successes divided by the total number of trials.

Sample Sizes

The number of individuals or observations included in a sample, crucial for determining the study's statistical power.

Expected Value

The expected value is a measure of the central tendency of a random variable, representing the average outcome one would anticipate over an infinite number of trials.

Sample Proportions

The fraction or percentage of samples in a category or exhibiting a characteristic, used to estimate population proportions.
