The diaphragm.
Suction is the force that "draws" or pulls rather than "drive" air into the lungs.When the diaphragm muscle pulls down, and the ribs expand slightly, the lungs also expand which sucks air into them.(see related links below)
When the lungs are expanded, this action takes place due to the diaphragm contracting during inhalation. During exhalation, the diaphragm relaxes.
the muscle that pulls down on the lungs, the decrease in pressure inflates the lungs, a good example is a ballon inside a pop bottle, with the bottom replaced with another balloon, when you pull down on it the balloon inflates.

The diaphragm pulls down and allows more air into the lungs.
The diaphragm is a muscle which helps control the breathing process. When the diaphragm contracts it pulls down on the lungs (it is connected by the plueral membrane and connective tissue.) this creates space for the air to be forced into the lungs . This is because there is greater pressure inside the lungs than outside the lungs, resulting in air rushing into the lungs, and vice versa when the diaphragm relaxes.
A network of muscles above the stomach but under the ribcage, called the Diaphragm, acts as a bellows and applies pressure on the lungs. It pulls down to cause the lungs to fill with air and pushed up to expel carbon dioxide from the lungs.
the first thing that happens when you breathe in is your rib cage rises and expands out. this gives your lungs room to inflate. then your diaphragm pulls down, causing air to rush from a high concentration into your lungs. (low concentration) as the air is sucked in your lungs inflate
No, it pulls down to draw air into 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.
The amount of force which gravity pulls down an object is called its weight.
When the diaphragm contracts, it pulls down and creates a vacuum in the lungs, which helps in breathing in.
