2.04 Understand the functions and disorders of the lymphatic system What are the functions of the lymphatic system? What is the importance of the lymphatic system as it relates to immunity? How do you relate the body s use of nutrients to the lymphatic system? What are some and how are they treated? 3
Functions What are the functions of the lymphatic system? 1. Fluid balance 2. Lymphocyte production 3. Filtration 4. Immunity 4
Fluid balance Collects fluid (approximately 1-2 liters/day)and returns it to the circulatory system Without an appropriate fluid balance lymphedema can occur causing swelling. Fluid IN Fluid OUT 5
Lymphocyte production Lymphocytes are a type of WBC They help to form antibodies at a site of inflammation helping to fight injury and disease 6
Filtration Filters out harmful bacteria 7
Immunity Immunity is the body s ability to resist infection. 8
Natural immunity Is the immunity you are born with It is inherited and permanent Consists of unbroken skin, mucus and tears 9
Acquired immunity: Passive Is borrowed immunity It is acquired artificially by injecting antibodies into a person s body. It only lasts 3-5 weeks. It is used when someone has been exposed to a virulent disease. 10
