Inhale — Ms

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. The Mechanics of Inhalation

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