Lymphatic system and nodes

• The lymphatic system has an important role in the proper functioning of the circulatory system by returning fluid to the blood
• During circulation fluid gets lost from blood vessels at capillary beds and seeps into the surrounding tissues
• Lymphatic vessels collect this fluid and direct it toward lymph nodes
• Lymph nodes filter the fluid of microorganisms and the fluid , or lymph, is eventually returned to the blood
• This function of the lymphatic system helps to maintain blood pressure and blood volume
