Inhale refers to the act of breathing in air through the nose or mouth. This process is essential for life, as it allows oxygen to enter the lungs, where it is then transferred to the bloodstream. The diaphragm, a muscle located beneath the lungs, contracts during inhalation, creating a vacuum that pulls air in. Inhalation is part of the respiratory cycle, which also includes exhalation, the process of breathing out. Proper inhalation is important for activities such as exercise, singing, and meditation, as it helps to increase oxygen supply and promote relaxation.
