What is the process of quiet inspiration and quiet expiration in the thoracic cavity?

I - Quiet inspiration is carried out almost entirely by the contraction of the diaphragm, which descends and pulls the lower lung surfaces downward.
II - The contraction of the scalene and upper serratus muscles raises the upper ribs and the external intercostal muscles raise the rest of the ribs, forcing the sternum outward and increasing the anteroposterior and transverse diameter of the thorax.
III - Quiet expiration is a passive process that occurs when the diaphragm relaxes, mainly causing a decrease in the capacity of the thoracic cavity and an increase in intrapulmonary pressure with respect to atmospheric pressure, causing air to leave the lungs.
IV - The elastic recoil of the lungs and the thoracic wall expel air from the lungs.
V - In forced expiration, the abdominal muscles contract, flattening the ribs, helping to decrease the anteroposterior diameter of the thorax. In addition, they increase intra-abdominal pressure and force the abdominal contents upward, against the diaphragm, pushing the lungs to help expel air.
VI - In forced inspiration, not only stronger contractions of the diaphragm and external intercostal muscles are required, but also the help of accessory muscles such as the sternocleidomastoid and anterior serratus muscles.
