when you breathe your incostral muscles contract and the diaphragm pushes your organs down to increase the area of the chest. there is no more space then there was before because the lungs have expanded. this causes the air pressure inside the lungs to fall below atmospheric pressure. the result is air rushing in to fill in the new space the lungs have expanded into. take a breath you can actually feel it!

What is the movement of air on and out the lungs?
The movement of air on and out the lungs is called respiration. The movement of air into the lungs is called inhalation (inspiration). The movement of air out of the lungs is called exhalation (expiration).
How does air out of your lungs?
air is pushed out of the lungs by the force of the rib cage relaxing
What is the principal driving force for exhalation at rest?
During exhalation at rest, the principal driving force is passive elastic recoil of the lungs and chest wall. As the diaphragm relaxes and the external intercostal muscles relax, the lungs passively recoil to their resting size, which pushes air out of the lungs. This process does not require active muscle contraction.
Excessive movement of air in and out of the lungs?
hyperventilation
What is the movement of air in and out of lungs called?
Inhalation and exhalation
What movement of air in and out of the lungs is called?
Inhalation and exhalation
What force speeds up the movement of an object?
The force that speeds up the movement of an object is typically the force of acceleration, which is generated by applying a driving force such as thrust, propulsion, or push. This force overcomes the resistance (friction, air resistance, etc.) to induce the object to move at a faster rate.
What are the three main driving forces of air motion?
The three main driving forces of air motion are pressure gradient force, Coriolis force, and frictional force. Pressure gradient force is the difference in pressure that causes air to move from high to low pressure areas. Coriolis force is the effect of the Earth's rotation that deflects moving air to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Frictional force slows down the movement of air near the Earth's surface.
Which is the movement of the chest that brings air into the lungs and removes waste gases?
When your lungs move to bring in air and remove gases you are breathing.
What is the main force for pushing air out of the lungs?
The main force for pushing air out of the lungs is the contraction of the diaphragm and intercostal muscles. During exhalation, these muscles relax, causing the volume of the thoracic cavity to decrease, which increases the pressure in the lungs, forcing air out.
What are the air force air field driving test answers?
What are the test answers to air field driving
Is it true that the force that drives air into the lungs comes from air pressure?
True
