Lymphatic System
Learning Goals: 1. I will be able to explain the role of the lymphatic system 2. I will be able to explain how the circulatory system and lymphatic system work together
What Does the Lymphatic System Do? The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.
