Case Study

Often after the surgical removal of a breast, lymph nodes, and lymphatic vessels—especially those in the upper arm—swelling occurs. What is the physiological reason swelling takes place? Why is removal of the axillary lymph nodes helpful?

Lymphatic System

Lymph nodes Filter lymph WBC formation

Thymus Produce T-cells

Tonsils Filter bodily fluids (saliva)

Spleen Phagocytosis Blood Reservoir

Types of Immunity

Non-specific Immunity Skin, tears, mucous membranes

Specific Immunity Natural Immunity

Active vs. Passive Artificial Immunity
