Question

Because the bell jar in the model lung cannot move, any changes in volume are a result solely of the movement of the rubber diaphragm. Match the position of the rubber diaphragm to changes in volume and pressure inside the bell jar and balloon size.

a. Galloons inflate
b. Balloons deflate
c. Volume inside bell jar increases
d. Volume inside bell jar decreases
e. Pressure inside bell jar decreases
f. Pressure inside bell jar increases

1. Rubber diaphragm up
2. Rubber diaphragm down

Answer 1

1. Rubber diaphragm up-

b. Balloons deflate

d. Volume inside bell jar decreases

f. Pressure inside bell jar increases

2. Rubber diaphragm down-

a. Galloons inflate

c. Volume inside bell jar increases

e. Pressure inside bell jar decreases

Step-by-step explanation:

The rubber diaphragm is the model to demonstart the various parts of the respiratory system and how they move during breathing process. In case of it moves down, the rubber diaphragm is stretched, the volume inside the bell jar increases which causes presursue decrease.

Balloon inhale or sucks in the air from outside and gets inflate. this increases the volume in the jar. The pressure is increased
