Inhalation (or inspiration) is the process of drawing air or other gases into the respiratory tract, primarily for the purpose of bringing oxygen into the body. It is a fundamental physiological function in humans and many other organisms, essential for sustaining life.
Inhaling and exhaling. Find out exactly why air goes in and out of the lungs. Discover how changes in lung volume affect air pressure, leading to the movement of air molecules in and out of the lungs. This process, crucial for respiration, is explained using a simple jar analogy.

Breathing ( spiration [1] or ventilation) is the rhythmical process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen .
Mar 10, 2016 · March 10, 2016. The diaphragm, a dome-shaped muscle at the base of the lungs, plays an important role in breathing — though you may not be aware of it. When you inhale, your diaphragm contracts (tightens) and moves downward. This creates more space in your chest cavity, allowing the lungs to expand.
