The movement of the diaphragm and intercostal muscles changes the volume of the thoracic cavity during breathing. When the diaphragm contracts and moves downward, it increases the cavity's volume, causing air to be drawn into the lungs (inhalation). Conversely, when the diaphragm relaxes and moves upward, the volume decreases, forcing air out of the lungs (exhalation). This pressure change is essential for the airflow in and out of the respiratory system.

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).
What causes static compliance in the lungs to decrease?
well .. the cause is if there is no air movement the Cst will decrease .
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
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 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.
What muscle contracts to cause a hiccup?
A hiccup is the movement of the diaphragm. The diaphragm is in the thoracic cavity just under the lungs. This organ helps to squeeze the lungs when you exhale in order to get all the air out of the lungs. Holding your breath causes the diaphragm to move downward and stop this movement.

Where can you find a diagram of human lungs?
The diaphragm of the lung is the muscle below the lungs that stretches the lungs, helping them expand when you inhale. When you exhale, it helps push air up out of the lungs.
What causes diminished breath sounds in emphysema?
The person's lungs are not moving air well in emphysema. Also irritants cause increased production of phlegm, which can reduce air movement, hence, diminished breath sounds.
How lungs get oxygen?
Oxygen enters the lungs when we inhale air. It travels down the airways and reaches the alveoli, tiny air sacs in the lungs where gas exchange occurs. Oxygen from the air diffuses into the bloodstream through the alveolar walls and is then carried to the rest of the body.
What makes air moves into and out the lungs?
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.Source(s):Structure and function of the body
