LymphImmuneSystem
Giselle gaona period 6
MAJOR FUNCTIONS
Lymphatic
The removal of excess fluids from body tissues
Absorption of fatty acids and subsequent transport of fat
Production of immune cells such as lymphocytes, monocytes, and antibody producing cells called plasma cells
Immune
to fight disease-causing germs
To recognize and neutralize harmful substances from the environment
To fight disease-causing changes in the body such as cancer cells
ANATOMY OF THE LYMPHATIC SYSTEM
The lymphatic system consist of lymph vessels, ducts, nodes and other tissues.
Around 2 liters of fluid leak from the cardiovascular system into body tissues every day
The lymphatic system is a network of vessels that collect these fluids or lymph.
Humoral response
Is mediated by antibody molecules that are secreted by plasma cells
Antigen that binds to the B-cell antigen receptor signals B cells and is internalized and processed into peptides that activate armed helpers.
Cellular Response
Is the end of the line for a signal brought to the target cell by a signaling molecule
some of the major ones include regulation of protein synthesis and activity as well as cell division, shape and growth.
ANTIGENS
Are molecules capable of stimulating an immune response
Each antigen has distinct surface features or epitopes
Antibodies are Y-shaped proteins produced by B cells of the immune system in response to exposure to antigens
Cells involved
Memory B cell:
B cells that are long lived and remember past antigen exposure
Natural killer :
They are the first responders of the immune system
T cells:
They mature in the thymus and differentiate into cytotoxic, memory, helper and regulatory T cells
Disorders associated with the immune system:
ASTHMA, ATAXIA TELANGIECTASIA, DIABETES TYPE 1
ANTIBODIES
are secreted into the blood and mucosa where they bind to and inactivate foreign substances such as pathogens and toxins
Antibodies activate the compliment system to destroy bacterial cells by punching holes in the cell wall
Immune defenses:
Innate immune response:
are the first line of defense against invading pathogens
Acquired immune responses:
is triggered by recognizing foreign antigen in the cellular context of an activated dendritic cell
