The Human Body /Lymphatic System Song /Anatomy

The video explains the lymphatic system, highlighting its role in removing toxins and transporting lymph fluid, which contains white blood cells to fight infections. It describes the formation of lymph fluid from interstitial fluid and its journey through lymphatic vessels to lymph nodes, where immune cells inspect and respond to pathogens. The structure of lymph nodes, including fibrous capsules and vessel flow, is detailed. The video concludes with health tips to support the lymphatic system, such as maintaining hygiene and consuming organic foods.
