Secret Lab 3: The Respiratory System

Professor Knowitall and his two assistants find out how our respiratory system works.

In this episode, Dr Bright is sent to a ski slope where she discovers how her blood cells transports oxygen to her muscles to keep them moving.

Back in the lab, Professor Knowitall shows Dr Spark the journey of oxygen and how it enters our bloodstream.

Meanwhile, Dr Bright rounds up her findings with a few sparks and bangs to demonstrate how energy, which keeps our body moving, is created.
