How does the lymphatic system work? Why is it not as well known/taught about compared to the other systems of the body?

The lymphatic system comes up a lot in things related to cancer. It never showed up in high school biology or textbooks. I know that it involves the fluid known as ‘lymph’ but I don’t really understand what lymph is even after researching it.

The lymphatic system is an odd beast for sure! It is responsible for the trafficking of your immune cells, which is why you hear about it when people talk about cancer. It is not always clear, but most of the time is. The times it’s not clear is is milky white, because they lymph also works with your digestive system to move Fat around. After a high fat meal, you lymph turns milky white. The main trafficking molecule needed to move fat around is call a Chylomicron and oddly enough, the main portal for dumping these molecules into the blood stream via the Thoracic duct. Yep you heard that right, fat is dumped into your blood stream right next to your heart. You never hear about chylomicron when it comes to heart disease either. Make you wonder why not?
