How to draw the human respiratory system diagram?
  • First, outline the thoracic cavity, neck, and head.
  • Draw two rounded, somewhat triangular shapes in the thoracic cavity.
  • These represent the lungs.Using lungs as a reference, draw an upside-down Y shape centered at the top quarter of the lungs and leading upward to the neck. This Y shape is the two bronchus trunks and the trachea. 
  • Continue the sketch of the trachea to the rest of the neck up to the mouth. Curving this structure through the mouth and to the lips will give you the shape of larynx.
  • Draw oesophagus parallel to the larynx.
  • Draw a flat kidney bean shape following the outline of the base of the lungs. 
  • Divide the right lung into 3 curved sections and the left lung into 2 curved sections.
  • Extend the branching of the bronchus in each lung.
  • Draw small grape-like structures attached to these bronchioles to represent the alveoli.
