Lymph Immune System Mia Gabriel Period 5
Major functions of the Lymphatic & immune Systems
-Vessels that assist in circulation of body fluid
-Lymphatic Vessels
:
-collect and carry one way of the excess fluid from interstitial places
Lymphatic:
-The organs, cells and biochemicals of the lymphatic system help defend diseases
Lacteals support transports fats to circulatory system
Immune System:
-Helps function the body to defense against infections with pathogens
-It allows the pathogens to keep out and attack from entering the body
Humoral Response and Cellular Response
-Anti-bodied mediated
-B lymphocytes
Humoral Response:
Mode of Action:
Antibodies circulating in serum
Purpose:
Primary defense against extracellular pathogens
-Circulating virus and bacteria
Cellular Response:
-Cell-Mediated
-T-Lymphocytes
-Mode of Action:
Direct cell to cell contact or secrete soluble products
-Purpose:
Primary defense against intracellular pathogens
-viruses and fungi, intracellular bacteria ,tumor antigens and graft rejection
Innate(natural)immune defenses and Adaptive(acquired)immune defenses
-Species Resistance:
diseases that affect other species
-Mechanical Barries:
Bodies first line of defense.
Innate(natural)immune defenses:
-unbroken skin and mucous membrane of the body it consist of mucus, sweat, skin and hair
-Chemical Barriers:
it kills and destroys pathogens of enzymes with sweat, mucus, tears and saliva
-characterized by redness, swelling, heat and pain
-Natural Killer (NK) Cells:
defends the body against viruses and cancer cells.
-NK cells chemicals that enhance inflammation
-Inflammation:
tissue response to actions of pathogen
-Phagocytosis:
Neutrophils and monocytes attack large and small particles
-potentially removes particles from the lymph
-Fever:
Offers powerful protection against infection by proper conditions of bacterial growth
-Naturally acquired passive immunity:
when antibodies are passed from mother to fetus and is short lived
-Artificially acquired passive immunity :
injection of gamma globulin containing antibodies and short lived
-Artificially acquired active immunity :
the use of vaccines without the person becoming ill
-Naturally acquired active immunity:
after exposure of the antigen
-Body's third Line of defense
Adaptive(acquired)immune defenses
Anatomy of the Lymphatic System:
-Has a resistance to diseases
-An essential role in the bodies defenses
-It drains excess fluids that authorize from the tissue
-Clean Fluids and it leaks proteins back to the blood
-Consist of nodes, ducts and Lymph Vessels
-Lymphatic System collects fluids that come from vessels
It has the opening around the mouth and throat
-Pharyngeal Tonsils, Palatine Tonsils and Lingual Tonsils
Tonsils:
Contain three masses of lymphoid tissue
Thymus:
it is located behind the sternum, above the heart and it shrinks
-Thymus secretes hormones called thymosins and they regulate T lymphocyte
-Surrounded by connective tissue capsule that extends
Spleen:
Contains blood instead of lymph
Upper left abdominal cavity, largest lymphatic organ
filters blood and removes damages
Bone Marrow:
Blood cells and immature lymphocyte formation
-B Lymphocyte or B cell maturation
Lymph Nodes:
Removes bacteria and cellular debris before lymph is returned
-lymph nodes enter from center of lymphocyte prodcution
Cells involved in the Immune System
T Lymphocyte:
-Direct destruction of virus in mutant cells and cells
-Has mutant of cells and involved in cell mediated immunity
-has been involved in cell mediated immunity
-Natural Killer(NK) Cells:
-B Lymphocytes:
-secretes antibodies from the lead of foreign material from indirectly
-Humoral or antibody-mediated immunity
Antigen and Antibodies
-Macrophages that has been encountered through the antigens
-The T cells must be activated antigens
-Antigen:
-Antibodies:
-Soluble protein secreted by plasma cells
-Carried by body fluids, binding to the antigens
-5 Major types of antibodies:IgG, IgA, IgM, IgD, IgE
Disorders associated with the Immune system
-Edema:
-interferes the flow in lymph
-develop a syndrome called elephantiasis
-fluids are not determined to return in the vascular system
-Lymphatic Filariasis:
-It happens during surgery, lymphatic vessels and tissue that has been removed
-It happens by swelling in the arms, legs, breast or genitals
-it is caused my parasitic worms that are spread by mosquitos
