The fluid that passes through our lymphatic system is called lymph.
Lymph's primary job is to restore surplus interstitial fluid and proteins to the bloodstream.
Lymph serves as a "middle man," transporting oxygen, food materials, hormones, and other metabolic wastes to body cells while also transporting carbon dioxide and other metabolic wastes from body cells to blood and ultimately into the venous system.
White blood cells: Our body is protected against infection by white blood cells.
Our white blood cells detect the infection site as they move through our circulation and tissues.
Acting like an army general to alert other white blood cells of the infection's location to aid in defending your body against an attack by an unknown creature.
Our white blood cell army fights the intruder after it has arrived by creating antibody proteins that adhere to the organism and kill it.
