Question

what is the inhalation of volume of thoracic cavity​

Answer 1

Answer:

During the process of inhalation, the lung volume expands as a result of the contraction of the diaphragm and intercostal muscles (the muscles that are connected to the rib cage), thus expanding the thoracic cavity. Due to this increase in volume, the pressure is decreased, based on the principles of Boyle's Law.

Lung volume expands because the diaphragm contracts and the intercostals muscles contract, thus expanding the thoracic cavity. This increase in the volume of the thoracic cavity lowers pressure compared to the atmosphere, so air rushes into the lungs, thus increasing its volume.

Answer 2

Answer:

during the process of inhalation the diaphragm muscles contract and become flat. At the same time, intercostal muscles contract to pull the ribs upward. this increase the volume of the chest cavity. The volume of lungs increases. As the air pressure in the lungs decreases, air moves into the lungs through the air passage.
