Lymphatic System Explained In Simple Words

The lymphatic system consists of a complex network of lymphatic vessels, glands or nodes, and organs, such as the spleen and thymus, extending throughout the body. Through it flows a fluid called lymph. The lymphatic system has three main functions. 1. It returns excess body fluid back to the blood circulation. 2. It helps the immune system detect pathogens and mount an immune response. 3. It aids in fat absorption.
