Lymphatics Flashcards
Lymphatic system
- function
- structure
- ‘Hoovers up’ anything left in interstitial fluid

Why are lymph nodes important in tumour spread?
If a tumour metastasises –> is likely to metastasise into the lymphatic system
–> If cancer cell is in a lymph node, can identify where it potentially came from
