Flexi Says: Lymph is a yellowish liquid that leaks out of tiny blood vessels into spaces between cells in tissues.
Lymph vessels make up a circulatory system that is similar to the cardiovascular system, which you can read about in a previous concept. Lymph vessels are like blood vessels, except they move lymph instead of blood.
Lymph nodes are small, oval structures located along the lymph vessels where pathogens are filtered out and destroyed.
