the diaphragm
The diaphragm is a muscle located below the lungs that contracts and moves downward when you inhale, creating more space for your lungs to expand. This allows for air to be drawn into the lungs for oxygen exchange. When you exhale, the diaphragm relaxes and moves back up, pushing air out of the lungs.
Oxygen moves into the lungs where it is absorbed into the bloodstream through tiny air sacs called alveoli.
The lungs move downwards when the diaphragm contracts and flattens, allowing air to be drawn into the lungs.
The diaphragm is the primary muscle responsible for breathing. When it contracts, it moves downward, creating a vacuum in the chest cavity which draws air into the lungs. When it relaxes, the diaphragm moves back up, pushing air out of the lungs.
During inhalation, the diaphragm contracts and moves downwards, causing the chest cavity to expand and draw air into the lungs. During exhalation, the diaphragm relaxes and moves upwards, allowing the chest cavity to decrease in size and push air out of the lungs. These movements ensure proper ventilation of the lungs.
when air moves out of the lungs, the air pressure decreases
The air moves from the outside into the lungs through the windpipe.
the lungs will moves down when breathe out air
inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.

Air moves into the lungs when the diaphragm is flattened. The diaphragm is relaxed (arched) during expiration.
The diaphragm moves down to make the lungs expand (inhalation)

The opposite. When you exhale, the diaphragm moves upward to push the air out of the lungs.
The muscle is the "diaphragm" muscle. It is located beneath the lungs. When it moves down and away, it creates lower pressure around the lungs, and the air pressure outside the body flows into the lungs. When it moves up and in, it compresses the lungs, increasing the pressure to force the air back out.
Air moves from the larynx through the trachea and then into the lungs. The trachea acts as a passageway that branches into the bronchi, leading to the left and right lungs. Once in the lungs, air travels through smaller bronchial tubes into the alveoli, where gas exchange occurs.
