Pulmonary ventilation or breathing has two phases. Inspiration or inhalation moves air into the lungs and expiration or exhalation moves air out of the lungs. The lungs are enclosed within the thoracic cavity. Thus changes in the shape and size of the thoracic cavity result in changes in the air pressure within that cavity and in the lungs. This difference in air pressure causes the movement of air into the lungs. Air moves from an area where pressure is high to an area where pressure is low. Respiratory muscles are responsible for the changes in the shape of the thoracic cavity that cause the air movements involved in breathing.
The abdominal diaphragm is (or should be) the major muscle driving respiration.

What else can I help you with?
When Air moves out of the lungs the pressure inside the lungs is?
when air moves out of the lungs, the air pressure decreases
Air moves from the outside into the lungs through?
The air moves from the outside into the lungs through the windpipe.
Why the rib moves up when you inhale?
Actually the ribs are moving outward and expanding as the lungs fill with air. The expansion of the ribs makes room for more air to enter the lungs.
What happens in the lungs when you breathe out air?
the lungs will moves down when breathe out air
What force cause air to move in an out of the lungs?
inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.
How air moves into and out the lungs?
breathing.
What moves air in and out the lungs?
the diaphragm
Air moves into the lungs when the diaphram muscle?
Air moves into the lungs when the diaphragm is flattened. The diaphragm is relaxed (arched) during expiration.
When air moves into the lungs when the diaphragm muscles do what?
The diaphragm moves down to make the lungs expand (inhalation)
The diaphragm moves air into and out of the what of a mammal?
