And that can lead to very serious medical conditions and medical complications. So to prevent this from happening, what our body does, and specifically what the lymphatic system does, is it drains and removes that fluid into the system of vessels we call lymph vessels or lymphatic vessels. These lymph vessels essentially connect with larger lymph vessels known as lymphanes. And along the lymph vessels we have these regions known as lymph nodes. And we'll talk about them in just a moment. And these lymph nodes essentially filter our lymph from different types of pathogenic agents.
