These movements increase the size of the thoracic cavity, creating lower pressure (negative pressure) inside the lungs compared to the outside air.

Air rushes in through the nose or mouth, traveling down the trachea, through the bronchial tubes, and into the alveoli (air sacs). Physiological Role ms inhale

Inhalation, or breathing in, is the active phase of respiration where air is drawn into the lungs, providing oxygen needed for cellular metabolism. It is a complex process controlled by muscle movements that increase the volume of the chest cavity, lowering the pressure inside and allowing air to enter.
