Lymph Immune Mykayla Sohn
Period 2
Major functions of the:
Immune system
Major functions
Fight pathogens and remove them from the body.
For example: bacteria, parasites, viruses, and fungi.
To fight disease causing changes in the body
For Example: cancer cells
To recognize and neutralize harmful substances from the environment
lymphatic system
Major functions
The removal of excess fluids from body tissue
Production of immune cells
For example
Lymphocytes,monocytes,and plasma cells
Absorption of fatty acids and subsequent transport of fat, chyle, to the circulatory system.
Anatomy of the Lymphatic System
Primary lymphoid organs
Bone marrow
Manufactures bone marrow stem cells and other substances, which in turn produce blood cells.
Thymus
Serves as the body's defense mechanism providing surveillance and protection against diverse pathogens, tumors, antigens and mediators of tissue damage.
Secondary lymphoid organs
Lymph nodes
Bean-shaped glands that monitor and cleanse the lymph as it filters through them.
Spleen
Removes damaged red blood cells from the body and keeps the circulating blood in the body clean.
Tonsils
Stop germs for entering the body through the mouth or nose.
Mucous Membranes
Protects the body from harmful external agents.
Immune Defenses
Adaptive (acquired) immune defenses
Humoral immunity
Secretes antibodies to fight against antigens.
Cell mediated immunity
Secretes cytokines and no antibodies to attack pathogens
Innate (natural) immune defenses
Mechanical Barriers
First line of defense for the body.
Example: Skin, hair,mucus, sweat
Chemical Barriers
Example: Gastric juice and lysosomes in tears.
Specio Resistance
Resistance to diseases that affect other species.
Natural Killer Cells
Defend the body against various viruses and cancer cells.
Secretes cystolic substances called perforins
Inflammation
Definition: tissues response to a pathogen
characteristics include redness, swelling, heat, and pain.
Phagocytosis
Remove foreign particles from the lymph
Fever
Powerful protection against infection by interfering with the proper conditions that promote bacterial growth.
Humoral and cellular response
Humoral
Deals with antigens from pathogens that are freely circulating, or outside the infected cells. Antibodies produced by the B cells will bind to antigens, neutralizing them, or causing lysis (dissolution or destruction of cells by a lysin) or phagocytosis.
Cellular
Process that involves the activation of phagocytes, antigen-sensitized cytotoxic T cells and the release of cytokines and chemokines in response to antigen.
Antigens and antibodies
Antigens
Molecules capable of stimulating an immune response.
Antibodies
Y-shaped proteins produced by B cells in response to exposure of antigens.
Cells involved in the Immune system
Neutrophils
Help fight infection by eating microorganisms and releasing enzymes that kill the microorganisms.
Monocytes
Regulate immunity against foreign substances, destroy cancer cells, and remove damaged tissues.
Lymphocytes
B Cells
At the center of the adaptive humoral immune system and are responsible for mediating the production of antigen-specific immunoglobin.
NK Cells
Control several types of tumors and infections by limiting their spread and subsequent tissue damage.
T Cells
At the core of adaptive immunity and tailors the bodies immune response to specific pathogens.
Disorders associated with the Immune System
AIDS
HIV, which causes AIDS, is an acquired viral infection that destroys important white blood cells and weakens the immune system.
Lupus:
A disease that attacks body tissues
Edema
Condition that interferes with flow in lymph
Caused when fluids aren't returned to the vascular system.
