How does the trachea filter air?

In the throat, the trachea, or windpipe, filters the air. The trachea branches into two bronchi, tubes that lead to the lungs. Once in the lungs, oxygen is moved into the bloodstream. Red blood cells collect carbon dioxide from the body’s cells and transports it back to the lungs.Click to see full answer. Also, how is air filtered in the respiratory system?When you breathe in, your respiratory system brings the oxygen into your body so that blood can deliver the oxygen to your cells. When you breathe out, you expel a gas called carbon dioxide. Little hairs inside your nasal cavity help filter the air you breathe in, and block dirt and dust from getting into your lungs. what happens to air in the nasal cavity? The Nose or Nasal Cavity As air passes through the nasal cavities it is warmed and humidified, so that air that reaches the lungs is warmed and moist.? The moisture in the nose helps to heat and humidify the air, increasing the amount of water vapour the air entering the lungs contains. Besides, where does air go after the trachea? As your lungs expand, air is sucked in through your nose or mouth. The air travels down your windpipe and into your lungs. After passing through your bronchial tubes, the air travels to the alveoli, or air sacs.How the respiratory system works step by step?Every time you breathe in air, your diaphragm tightens, moving downward to make space in your chest. Your lungs expand, pulling air in through your nose and/or mouth. That air then moves down your trachea, through your bronchi and into the bronchioles, where it enters your alveoli.
