Lymphatic System
Lymphatic System Anatomy
Drain excess fluid from tissue
essential role to body defenses and resistance to diseases
return clean fluids and leaked proteins back to blood
Immune System
recognise and destroy the microbe quickly if it enters the body
makes antibodies and uses them to specifically fight certain germs
fight harmful substances and germs that enter the body
Bone Marrow
Lymph nodes
Spleen
Thymus
Tonsils
Mucous Membranes
Adaptive Immune Defenses
Innate Immune Defenses
protects against all antigens
defense system in which you were born
barriers that keep harmful materials from entering your body.
barriers form the first line of defense
the humoral response and the cell mediated response
B cells and T cells

Antibodies
Antigens
Y-shaped protein used by the immune system to identify and neutralize foreign objects such as pathogenic bacteria and viruses
recognizes a unique molecule of the pathogen, called an antigen
known as an immunoglobulin
molecule or molecular structure
bound by an antigen-specific antibody or B-cell antigen receptor

Humoral Response
Cellular Response
The presence of antigens in the body normally triggers an immune response
Others activate membrane enzymes, which produce certain intracellular chemical mediators
binding of chemical signals to their corresponding receptors
retains a memory of a specific pathogen after an infection is over
provides immunity to the pathogen
B cells produce antibodies against antigens in blood and lymph.
cellls in the immune system
lymphocytes
neutrophils
monocytes/macrophages
Disorders associated withthe Immunesystem
Rheumatoid arthritis
Lupus.
Type 1 diabetes
a type of white blood cell in the immune system
protect us from infections, among other functions
bone marrow derived leukocytes that circulate in the blood and spleen
The immune system attacks the cells in the pancreas that make insulin.
This type of arthritis causes swelling and deformities of the joints.
This disease that attacks body tissues, including the lungs, kidneys, and skin
