Function of Lymphatic system
Pick up extra fluid and return it to blood stream
Flow of Lymphatic system
One way system towards the heart, flaping mini valves act as one way swinging doors, Open when pressures unequal. Milking actions of muscles move also
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
Phagocytes
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
Complement
Group of at least 20 plasma protiens that circulate in the blood in an inactive status. Later binds to bacteria and attacks
3 important aspects of the immune response
1. antigen specific
2. systemetic
3. has "memory"
Humoral immunity
antibody
Cell mediated immunity
WBC's
Antigen
any substane capable of exciting our immune system and provoke immune response
Hapten
allergins
Immunocompetence
Capable of responsding to a specific antigen by binding to it
Cytotoxic T cells
Act as "directors" or "managers", Interact with B cells and tell them to divide more rapidly
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
Clonal Selection
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
monoclonal Antibodies
exhibit specificity for one antigen
Xenografts
tissue harvested from other species
Allografts
tissues taken from another person
Isografts
tissue donated from identical twin
Autografts
Tissues taken from oneself, another location
Peyer's Patches
resemble tonsils, found in small intestine
