β 9y agoThe primary muscle responsible for air entering the lungs is the diaphragm. The diaphragm is a dome-shaped muscle that lies just below your lungs, internally separating the thoracic cavity from the abdominal cavity. When you take in a deep breath, your diaphragm (along with other accessory muscles) contracts and flattens while your chest wall expands creating a negative pressure within the thoracic cavity. This allows air to move from an area of high pressure to an area of lower pressure during inhalation.

It contracts and relaxes to help pull air into the lungs and push it back out. The diaphragm contracts and moves lower which expands the ribs and allows air to move into the lungs. When it relaxes, the ribs contract and push air back out of the lungs.
The diaphragm is an important muscle involved in the breathing process. When it contracts, it helps to expand the lungs, allowing air to be drawn in. When it relaxes, it helps to push air out of the lungs.
This the diaphragm. When it contracts it lowers and air can rush into the lungs. When it relaxes air leaves.
Lungs do not contain muscle tissue. air enters your lungs when the muscular diaphragm contracts, pulling your ribs up and out. The diaphragm relaxes when you exhale.
The diaphagm - is a sheet of muscle that separates the lungs from the abdomen. When we breathe in - it contracts, which makes the lungs expand - drawing air in. When we breathe out - it relaxes, allowing the air to escape.
The Diaphragm - a membrane of muscle and tendon, flexes to reduce ambient pressure in the thorax, and cause the lungs to compensate by drawing in air. Exhalation works in reverse.
Your diaphragm contracts and expands when you breath. When the diaphragm contracts, air rushes into the lungs. When the diaphragm relaxes, air is exhaled.
The process of breathing involves the contraction of the diaphragm, a dome-shaped muscle located below the lungs. When you inhale, the diaphragm contracts and moves downward, creating more space in the chest cavity for the lungs to expand and fill with air. When you exhale, the diaphragm relaxes and moves back up, pushing the air out of the lungs.
Lungs are not muscles. They are made up of connective, epithelial, and nervous tissues. The diaphragm is the muscle that contracts and relaxes to expand and relax the chest cavity. Your lungs just fill with air -- which is why they appear to be moving (much like a when a balloon fills with air).
The diaphragm is the primary muscle responsible for breathing. When it contracts, it moves downward, creating a vacuum in the chest cavity which draws air into the lungs. When it relaxes, the diaphragm moves back up, pushing air out of the lungs.
The diaphragm is a dome-shaped muscle located below the lungs that contracts and relaxes to help with breathing. When it contracts, it flattens out, creating a vacuum that allows air to be drawn into the lungs. This muscle plays a crucial role in the process of respiration by facilitating inhalation and exhalation.
The diaphragm relaxes to help squeeze the air out of your lungs. When the diaphragm contracts, it flattens and pulls air into your lungs. When it relaxes into its dome-shaped position, air is pushed out.
