Kayla Rodriguez P.3 Lymphatic & Immune system
Functions of Lymphatic & Immune system
Lymphatic system carries and collects excess tissue fluid from intersitial spaces
The immune system is what protects the body against infections and the body cells
Innate(natural) & Adaptive (acquired) immune defense
Innate
Guards against many types of pathogens and responds quickly
Includes species resistances which is resistant to diseases that affect other species
Includes chemical barriers, mechanical barriers, Natural killer cells, Inflammation, phagocytis, and fever
Adaptive
Responds against a specific type of pathogens and responds more slowly
Uses specialized lymphocytes and secretes cytokines or antibodies
Disorders of immunity system
Small Pox
Haemophillus Influenzae
Cholera
Menigitis
Rubella
Toxoplasmasis
Whooping Cough
Polio Myelitis
Malaria
Tuberculosis
Tetanus
Measles
Pinworm Infection
Hand, Foot, Mouth Disease
Chicken Pox
Location of Lymphatic organs & functions
Thymus
Location: superior surface of the heart
Function: Programs immune system to recognize itslef
Lymph Nodes
Location: neck, underarm, abdomen, and groin
Function: Cleanses lymph and site for lymphocytes activation
Spleen
Location: Left hand side of the abdomen
Function: Cleanses blood and removes aged and defective RBC's, stores platelets, monocytes, and iron
Bone Marrow
Location: in flat bones like ribs, pelvis, sternum, etc
Function: Produces WBC's, elements of blood, and RBC's
Tonsils
Location: Back of the throat
Function: Stops germs from entering through the mouth and the nose
Peyers Patches
Location: Walls of the small intestine
Function: Preventing Infections
Lines of defense
Second
Natural Killers Cells
defends the body against viruses and cancer cells by secreting cytolic substances that break down cell membranes of pathogens
Phagocytis
engulfment and digestion of pathogens and foreign particles
Chemical Barrriers
kills many pathogens by using enzymes like pepsin in stomach and lyzomes in tears
Fever
creates hostile environment for pathogens that survive under normal conditions
Inflammation
stops the spread of pathogens and which increases blood volume and causes heat
Third
Cellular Immune system
Humoral Immune Response
First
Mechanical Barrier
Prevents entry of certain pathogens by providing physical separation of pathogens and internal tissues
Artificial Vs Naturally acquires immunity
Natural is when it is exposed to the antigen
Natural Active Immunity antibodies made after exposure to an infection
Natural Passive Immunity is Antibodies transmitted from mother to baby
Artificial is when it occurs through the use of a vaccine
Artificial Active immunity is antibodies made after getting a vaccine
Artificial are antibodies acquired from an immune serum medicine
Cells in immune system & functions
B cells
Create Antibodies
Binds to pathogens or foreign substances to neutralize them
In bone marrow and stays in bone marrrow
T cells
Is in bone marrow and matures in thymus
Provides Cellular Immune Response they interact with antigen- bearing agents to destroy them
Macrophages
helps in destroying the pathogen
Cytotoxis T cell
monitors body cells, recognizes and eliminating cancer cells
Helper T cell
Stimulates B cells to produce antibodies against displayed antigens
Memory T cell
quicks responds to any future exposures to the same antigen
Passive Vs Active immunity
Active
Obtained through antigen exposure
Immune response occurs in a person which antibodies and memory b cells are produced; long lasting immunity
short term
Passive
obtained by recieving antibodies
since there is no antigen contact & no immune response occurs, no memory b cells are produced; short term immunity
Long term
Humoral and Cellular response
Cellular
T cell activation requires an aquire with a antigen presenting cell
Major histocompatability proteins help T cells recognize displayed antigens
MHC are macrophages acting as antigen presenting cells
CIR is cell to cell contact
Humoral
antibodies that travel throughout the body fluids to attack and destroy antigens
the activation of b cells when encounter by an antigen that matches receptors
Helper T cell encounters b cells that encounter antigens, then helper t cell releases cytokines that activates B cell
Antigens & antibodies
Antigen
it is a foreign substance that enters the body and can trigger an immune system
Antibodies
it is a protein produced by the immune system to attack and destroy the antigens
immunoglobins
