Right Lymphatic duct
Drains R arm and R side of head and throax
Thoracic Duct
Recieves all lymph except for R arm and R side of head and thorax
Macrophags and Lymphocytes in lymph system
Within lymph nodes, engolf and destroy bacteria, viruses and other foriegn substances before returning to blood system
Natural Killer cells
promote cell lysis by direct cell attack against virus infected or cancerous body cells, do not depend on antigen. POLICE
Macrophages or neutrophil
Inlammatory response
Release of histamine and kinins: Cause bl. vessels to dialate and become leaky, activate pain response and attract WBC's to areas
Group of at least 20 plasma protiens that circulate in the blood in an inactive status. Later binds to bacteria and attacks

Cytotoxic T cells

Supressor T cells
Release chems that supress activity of both T and B cells, for winding down
Memory cells
B cells
Capable of later binding with Antigen and then responding to it

Lymphocyte begins to grow and then multiply rapidly to form an army of cells exactly like itself and bearing same antigen binding sites
Immunoloigical memory/Secondary responses
After B cell becomes sensitized to certain antigen, later immune response is this... faster, more eff+ d/t preps made
