Contractions of the diaphragm and the intercostals muscle change the size of the thorax. Because of this, it causes air to move in and out of the lungs. The circulatory system releases CO2 or gaseous wastes to the lung where it is exhaled from the body
Your lungs are the largest breathing muscle in your body.
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.
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).
inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.
A mussel is a shellfish. - You are referring to a 'muscle', and animals get air through the trachea into the lungs as the diaphragm muscle expands and contracts.
The diaphragm is the main muscle involved with the respiratory system. It either contracts or expands to allow air in or out of the lungs, which makes you breathe.The diaphragm is the main muscle involved with the respiratory system.

The diaphragm, a muscle below the lungs, contracts to pull air into the lungs. In order to forcefully exhale, both the abdominal muscles and the internal intercostal muscles can be contracted to compress the lungs.
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 is a strong wall of muscle on the bottom of the chest cavity. As this wall of muscle expands downward, a vacuum is created which pulls air into the lungs. As the diaphragm returns to it's original position, air is pushed out of the lungs.
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 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 main muscle that helps us to breathe is the diaphragm. When it contracts it creates a lower pressure area inside the lungs than is in the outside air, and this basically sucks air into the lungs. The lungs exhale through their own natural recoil.
