Lymphatic System – movement of clear fluid (lymph) towards the cardiovascular system and acts as a store of lymphocytes for immune protection.

Lymphatic System Organs: Lymph notes and Lymphatic vessels Tissue: Epithelial Cells: Leukocytes (lymphocytes) Molecules: Lymph Fluid (water)

Key points: Plasma from blood travels into the interstitial space Lymphatic capillaries take up plasma and it becomes lymph - This is moved back to the blood. Lymphocytes live in the lymph nodes – which detect disease and kill any pathogens Nursing Assessment - Swelling of limbs or organs - Swollen nodes

A healthy lymphatic system therefore should include 1) Fluid does not pool in legs and arms 2) Fluid does not pool around core organs 3) Non- swollen lymph nodes (though this is healthy if they are stopping a pathogen)

So What? Summary Key Terms- these are taken from our discussions. Please note these are not exact definitions but provide a general understanding. Immune system – i movement of clear fluid (lymph) towards the cardiovascular system and acts as a store of lymphocytes for immune protection. Organs: Lymph notes and Vessels Tissue: Epithelial Cells: Leukocytes (lymphocytes) Molecules: Lymph Fluid (water) Key Terms Capillaries – where the arteries and veins join and diffusion occurs Plasma – Fluid of the blood that helps diffusion in the tissues Interstitial space – gap between cells of the tissue Lymph – Fluid in the interstitial space that moves into the lymphatic vessels Lymphatic vessels - tubes that move lymph back to the veins of the cardiovascular system Lymph nodes – collection of lymphocytes and macrophages around that collect dead cells and pathogens in the lymph tissue Spleen – organ that filters the blood of all old and dying red blood cells, stores platelets to be released into the blood as a result of blood loss, contains lymphocytes and macrophage to attack infections in the blood. Peyer’s Patch – Lymphatic tissue in the small intestines full of lymphocytes to kill pathogens that enter the small intestines Tonsils – (2 lingual, 2 palatine and 1 pharyngeal) contain lymphocytes to kill and capture inhaled or ingested substances. Thymus – Produces and trains T cells during foetal development and childhood A healthy lymphatic system 1) Fluid does not pool in legs and arms 2) Fluid does not pool around core organs 3) Non- swollen lymph nodes (though this is healthy if they are stopping a pathogen) Nursing Observations: 1) Skin assessments 2) Immune assessments
