Did you know your body has its own version of a sewer system?
A good system for handling excess water and debris is an important part of any community.
It helps take away contaminated substances that might harm us.
Engineers have designed great systems of pumps and pipes to help our sewage systems do these important jobs.
Most of the time we barely notice these systems unless they fail to work.
Фу!
It turns out your body has a similar system for dealing with excess water and contaminated substances.
There are millions of tiny vessels in your body whose job is to gather excess water, proteins, cells, and various bits of debris.
This is called the lymphatic system.
The water which is leaked out of your blood vessels is returned to the bloodstream in your shoulder so you don't blow up like a big water balloon.
