Q: Paragraph- Sent 1: Breathing is the process of moving air into and out of the lungs.
Sent 2: The process depends on a muscle called the diaphragm.
Sent 3: This is a large, sheet-like muscle below the lungs.
Sent 4: Inhaling, or breathing in, occurs when the diaphragm muscle tightens.
Sent 5: This increases the size of the chest.
Sent 6: This too decreases air pressure inside the lungs.
Sent 7: This action allows air and gases to enter the lungs.
Sent 8: Exhaling, or breathing out, occurs when the diaphragm muscle relaxes.
Sent 9: This decreases the size of the chest.
Sent 10: This increases air pressure inside the lungs.
Sent 11: This action allows for air to leave the lungs.
Sent 12: When you inhale, air enters the respiratory system through your nose and ends up in your lungs, where gas exchange with the blood takes place.
Sent 13: What happens to the air along the way?
Sent 14: In the nose, mucus and hairs trap any dust or other particles in the air.
Sent 15: The air is also warmed and moistened.

Sent 17: The air then finds its way to the lungs.
Sent 18: In the chest, the windpipe splits so that air enters both the right and left lung.
Question: Why inhaling increases size of chest.

A:
Due to decreases in air pressure inside the lungs.
