|
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
|
