trachea, respiratory anatomy, airway structure. Airflow management. Bronchi expand during inhalation. Lungs oxygenate circulating blood. Tracheal health essential for breathing.

Coughing When a foreign object lodged in the trachea (windpipe) forces a person to cough, the diaphragm thrusts upward causing an increase in pressure in the lungs. This is accompanied by a contraction of the trachea, making a narrower channel for the expelled air to flow through. For a given amount of air to escape in a fixed time, it must move faster through the narrower channel than the wider one. The greater the velocity of the airstream, the greater the force on the foreign object. X rays s
