呼吸/respiratory cycle in English/Lung elasticity

The lungs have inward elasticity. This works towards decreasing the lung volume. The larger the lung volume, the larger the elastic force.


Let's suppose that there are 'rubber bands' inside the lungs, and that they are lightly stretched. When the lung volume is increased, the 'rubber bands' are strongly stretched.

1.

The lungs have inward outward elastic force. The force is larger smaller when the lungs are increased in volume.

2.

The elastic force of the lungs is larger when the lungs are increased decreased in volume.

3.

The elastic force of the lungs is smaller when the lungs are increased decreased in volume.
