Main functions of the immune and lymphatic systems

1. Absorb fats and fat-soluble vitamins through the lacteals of the small intestine

2. Remove waste products from the tissues and cooperate with the immune system in destroying invading pathogens

3. Return filtered lymph to the veins at the base of the neck
