Question

read the text.
the respiratory system is composed of airways, lungs, blood vessels, and muscles working together to supply oxygen to all parts of your body. the diaphragm, a muscle located beneath the lungs, plays an important role. when you inhale, the diaphragm squeezes, or contracts, and moves downward. as a consequence, there is more room for the lungs to expand as they fill with air. when you exhale, the diaphragm relaxes and moves upward, which leads to air being pushed out of the lungs.
match causes with their effects.
the diaphragm relaxes and moves upward. the diaphragm contracts and moves downward.
cause effect
air moves into the lungs.
air moves out of the lungs.

Explanation:

The text states that when the diaphragm contracts and moves downward (inhale), lungs expand to fill with air (air moves in). When it relaxes and moves upward (exhale), air is pushed out of the lungs.

Answer:

• The diaphragm contracts and moves downward: Air moves into the lungs.
• The diaphragm relaxes and moves upward: Air moves out of the lungs.
