LYMPHATIC SYSTEM
-
-
Recognition of Enemy
-
-
-
-
own recognition proteins APC cells,
-
Destruction of the Enemy
cytoplasm to leak out, therefore killing the cell.
Call off Attack
T-helper cells call in the T-suppressor cells and they release chemicals that call in cells to start the clean-up.
Future Protection
remember this antigen and proliferate, so an attack on the same antigen will start faster.
Defenses
-
Barriers
skin, saliva, lysozyme, stomach acid
-
-
Complement
plasma proteins produced in the liver ,form cascade effect to destroy the pathogen
-
-
-
Inflammation
heat, redness, pain and swelling.
-
-
-
-
-
-
Lymphatic Cells, Tissues, and Organs
-
Bone marrow
-
leukocytes /white blood cells,body against foreign molecules.
Spleen
-
-
-
-
WHITE PULP
immunological portion of the spleen. T-cell lymphocytes, B-cell lymphocytes, and other white blood cells.
-
-
FUNCTIONS
lymphatic vessels next to the blood vessels=remove excess fluid from the interstitial space
--> back to blood
-
-
building immunity, infectious diseases or other foreign molecules in the body
Specific Defenses
Antigen
bacteria, viruses, fungi, asbestos, chlorine, or even the wrong blood type
-
-
Lymphocytes
T-cell lymphocytes
produced in the bone marrow, move --> bloodstream -->thymus= maturation.originate in the red bone marrow.
-
Humoral Immunity
-
B-Cells
-
-
comes across the T-cell,that has already been stimulated by the specific antigen.
Antibodies
-
-
-
Antibodies are also called immunoglobulins .A globulin is a protein-> immune system. There are 5 types of antibodies that are made in the body:
-
can attack antigens by agglutination, precipitation,opsonization
Immune Response
-
Autoimmunity
-
rheumatoid arthritis, Grave's disease,
fibromyalgia, and systemic lupus erythematosis
-
