the diaphragm is a muscle located below the lungs. When the muscle tissue of the diaphragm contracts, it moves down, creating a vacuum inside the lungs, and pulling air into them. To breathe out, the diaphragm simply relaxes, springs back up, and the air is expelled. Not all of the air ever comes out of the lungs during an exhale.
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~Pulmonary Ventilation is the moving of air in and out of the lungs.
The diaphragm is a muscle that forces air in and out of the lungs. It is a muscular membrane located below the lungs. When it moves up, it reduces the volume of the lungs therefore forcing the air out. When it moves down, the volume of the lungs increases forcing the air in through the wind pipe (trachea)
The lungs compress using muscles to exhale and expand to inhale
In health, the diaphragm is able to move up and down from moving air in and out of lungs. But in some lung conditions, this movement is restricted.

Because the action of your chest moving, coupled with your diaphragm - is what draws air into the lungs.
By the water moving on it makes it get wet and causes it to move

Well, you'd still be able to move your chest, but w(o the lungs there'd be nothing to collect the oxygen that you need out of the air.
by moving their wings up and down dumbo
The use of a machine to move air. In medical terms, a machine to aid a person in breathing by moving air into and out of their lungs.
No, it pulls down to draw air into the lungs.
By breathing your stomach goes up and down and also your heart is still moving.
When you move the slide to the left it looks like your moving the slide to the right(same thing w/ left side) and if u move the slide up it looks like your moving it down(same thing w/ moving it down)
