Step: 1

Draw an upside “Y” shape, then right underneath that draw an upside down “V”.

The upside down “Y” and “V” we just drew is called the trachea, and it is the tube that the air you breathe goes down. The trachea is the part of the tower that you dropped down when you were oxygen on the drop tower ride.

Step: 2

Draw 2 lumpy triangles attached to the ends of the trachea (upside down “Y” and “V”).

WWhat you just drew are the lungs themselves, and the main structure of the drop tower ride you were just on.

Step: 3

Continue the lines of the trachea into the lungs making a big sideways “V” shape.

Step: 4

Now draw 3 smaller sideways “V” shapes inside each of the larger sideways “V” shapes.
What you just drew are called bronchi, and bronchi are the tubes that carry oxygen from the trachea to the balloon like sacs that are full of blood.

Step: 5

Draw a bunch of overlapping circles at the ends of the bronchi (the sideways “V” shapes).
The circles you are about to draw are called alveoli, and those are the balloon like sacs that are full of little tiny blood vessel. This was the part of the of the drop tower ride, where you get absorbed into the bloodstream.

Step: 6

For extra credit you can add the lines on the trachea.
