The diaphragm will contract and become flat instead of curved. This will give more air in the ribcage for the lungs, which now have a lower pressure (x amount of particles in a larger space). This draws air in from the outside as the pressure is higher outside of the lungs. Hence why you breathe. The ribcage will push up and outward as the lungs expand.
Inhalation
The act of taking in air as the diaphragm contracts and moves downward is called inhalation. During inhalation, the chest cavity expands, creating a vacuum that draws air into the lungs. This process allows for oxygen to enter the body and be distributed to the cells for respiration.
The diaphragm is a dome-shaped muscle that contracts and relaxes during breathing. When it contracts, it flattens out and pulls downwards, creating a vacuum that expands the chest cavity and draws air into the lungs. When the diaphragm relaxes, it moves back to its original dome shape, pushing air out of the lungs as the chest cavity decreases in size. This process of contracting and relaxing allows for inhalation and exhalation, enabling breathing to occur.
To breathe in your chest expands, creating a vacuum and thus drawing new air in. The new air contains a lot of oxygen (20%). To breathe out the chest contracts , forcing out the used air from which some of the oxygen has been removed and been replaced by carbon dioxide.
The pectoralis minor primarily aids in the inferior rotation of the scapula. When it contracts, it pulls the coracoid process of the scapula downward, which contributes to this rotational movement. This action is important for various arm movements, particularly those involving adduction and extension.

During inhalation, the diaphragm contracts and moves downward, allowing the lungs to expand and fill with air. This creates a vacuum in the chest cavity, drawing air into the lungs. During exhalation, the diaphragm relaxes and moves upward, forcing air out of the lungs.
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 diaphragm is the main muscle used when breathing in. During the diaphragmic contraction, the diaphragm pushes downward and pulls on the pleural cavity which allows air to flow into the lungs.
The major muscle that the body uses for breathing The above answer is of course correct for the thoracic diaphragm but there are others for example the pelvic diaphragm. A diaphragm is a domed muscular wall the reperates to regions. When is contracts it flattens to increase pressure on the inside of the dome and decrease pressure on the outside of the dome. In the case of the pelvic diaphragm is domes downards and contracts to resisf the increased pressure from the thoracic diaphragm on the abdomen during inhalation.
The primary muscle that aids breathing in a pig is the diaphragm. This dome-shaped muscle separates the thoracic cavity from the abdominal cavity and plays a crucial role in respiration by contracting and relaxing to facilitate the inhalation and exhalation of air. When the diaphragm contracts, it moves downward, creating a vacuum that pulls air into the lungs. During exhalation, the diaphragm relaxes, pushing air out of the lungs.
The diafragm moves downward and the intercostal muscles contract pushing the chest outward and upward causing negative pressure in the lung structure - air will allways move from a high pressure area to a low pressure area, hence, into the lungs.
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.
When you breathe, your diaphragm pulls downward which should create a vacuum within the chest cavity, but instead of that happening, your lungs expand because it is connected to your airway. When you breathe out, your lungs collapse due to your diaphragm returning to its original position.
When a muscle contracts, it pulls with a force generated by the muscle fibers contracting and shortening.
