Question

Answer in one word.

3. Volume of lungs increases during this process​

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.

Answer 2

During the process of inhalation, the lung volume expands.
