Did you know?

Lymph is a pale liquid in the body that helps maintain fluid balance and removes bacteria from tissues. Today, we understand that lymph plays an important role in the body's immune system. In the past, however, it was commonly believed that an excess of lymph caused sluggishness—hence the "sluggish" meaning of lymphatic. The word lymph comes from Latin lympha (meaning "water" or "water goddess"), which itself may be a modification of the Greek word nymphē, meaning "nymph." Both lymph and its related adjective lymphatic have been used in English since the 17th century.
