TOPIC 1: Introduction to Nursing
Learning Goal C: Identify the systems of a healthy body
HLT33115 Unit: HLTAAP001 - Recognise healthy body systems
Related Assessment: Task C

2. Recap -

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

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

5. 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

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

7. So What. Summary Key Terms- these are taken from our discussions
So What? Summary Key Terms- these are taken from our discussions. Please note these are not exact definitions but provide a general understanding.
A healthy lymphatic system
Fluid does not pool in legs and arms
Fluid does not pool around core organs
Non- swollen lymph nodes (though this is healthy if they are stopping a pathogen)
Nursing Observations:
Skin assessments
Immune assessments
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
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
