How to Draw the Respiratory System Diagram for Kids

1. Begin the respiratory system diagram for kids outline by drawing the face.

Use a long curved line to draw the face in profile. Use shorter curved lines to outline the eye, eyebrow, and oval-shaped pupil of the eye.

2. Use a series of curved lines to draw the back of the head, hairline, and ear. Notice how the lines meet at jagged points to lend texture to the hair.

3. Use a series of overlapping curved lines to sketch the shoulders, torso, and upper arms.

Then, begin drawing the internal structures of the cross-section. Draw a long curved line from the nose and a "V" shaped line behind the mouth.

4. Draw another long curved line from the mouth. Connect it to the previous long line by drawing a rounded trapezoid shape.

In the chest cavity, enclose the two rounded shapes of the lungs. Connect one lung to the trapezoid shape with a long curved line.

5. Draw curved lines between the lungs and between the trapezoid and the opposite lung. Within the first lung, use curved lines to begin drawing a branching structure.

6. Complete the branching structure within the first lung and begin drawing it within the second lung.

7. Continue drawing the branching structure.

8. Complete the branching structure. Band the trachea and bronchus - the tubes leading to the lungs - with curved lines.

Enclose a "C" shape below the lungs with two curved lines. Label the nasal cavity and draw a straight, diagonal line between the written word and the body part.

9. Label the remaining parts. Beginning at the bottom and working clockwise, they are the diaphragm, bronchioles, trachea, pharynx, larynx, lungs, bronchus, and alveoli.

Notice that some have not just one but two or three pointing lines.

Your respiratory system diagram is now complete. Color your drawing. Be sure to use different colors for the different parts to make them easy to see.
