Medical Assistant Prep / Unit 4 MAS 081 short lesson, about 20 seconds
The Lymphatic System
Captions available
The idea
The lymphatic system returns fluid to the blood and helps defend the body.
In practice
Lymph nodes, small bean-shaped structures along the lymphatic pathways, filter the lymph through dense clusters of white blood cells before it returns to the bloodstream.
Where people slip
Swollen lymph nodes are a finding to report, not one to explain to the patient.
