-contains WBC, fats, water, proteins, salts...
Lymphatic capillaries - -absorbs fats & transports clean lymph fluid to the blood
stream
-Connected to capillaries of cardio system
Flow of lymphatic capillaries - Lymph Cap -> large lymph vessels -> venous blood
of the cardio system
What is the lymphatic system? - helps with immunity to defend the body against
disease
Where are groups of lymph nodes located? - axilla, groin, neck, intestinal regions
