Lymphatic System


We just learned about Presbyopia.

We've learned a whole lot about Eyes, from the Cornea, Pupil, Iris and Retina to the Rods, Cones and Fovea!

Let's move on now and learn about something else, called the Lymphatic System.

This is a part of the body that helps make new blood cells, and also helps fight off diseases.
It's part of both the circulatory system and immune system, and goes through the whole body.

The lymphatic system isn't as well known as other parts of the body like the bones or muscles, but it was discovered over 300 years ago, so scientists have been studying it for a long time to figure out how the body works.
