Cholestrobot Body Route
A person swallows many Cholestrobots in one

Cholestrobot is absorbed into the blood stream
through the small intestine.

Each Cholestrobot uses cameras and
ultrasound sensors combined with an
electronic map to navigate the blood vessels.

Each Cholestrobot cleans at the site their map
was programmed to follow.

When the cleaning is finished the
Cholestrobots will enter the kidneys and exit
through the urinary system.
