THE LYMPHATIC SYSTEM
Take the extra fluid from the tissues (lymph) and bring it back to the ciruclationWorks with the immune system to protect against infections

Immune system
The physiological function of the immune system is defense against infectious microbes; However, noninfectious foreign substances and products of damaged cells can also trigger immune responses.
Innate immune system
Adaptative immune system
We are born with itThe answers are not very specificThey do not generate memoryComponents:1. Barriers (Physical, chemical, and microbiological)2. Cells (macrophages, neutrophils, natural killers)
We acquire it over timeThe responses are highly specific and diverseThey generate immunological memoryComponents3. B lymphocytes (antibodies), T lymphocytes (direct attack)
1. Barriers
2. Innate immune cells
3. Adaptative immune cells
They are physical, chemical or microbiological barriers that stop infection.
DEFENSE LINES
They are cells and systems of the innate system that attack the infection
They are adaptive components that develop specificity and memory
Physical barriers
First defense line
Chemical barriers
Biological barriers
Macrophages
Second defense line
Natural Killers
B lymphocites
Third defense line
T lymphocites
Antibody antigen
Antigen is from the pathogen
Antibody is from the immune system
It is a portion or part of a pathogen (microbe) that is capable of being recognized by the immune system.
Remember that a pathogen is any microorganism (virus, bacteria, parasitic fungus) capable of causing disease.
They are proteins produced by B lymphocytes found in our body and that are capable of recognizing and neutralizing (stopping, attaching) to antigens.
ALLERGIES
Physiology: Exaggerated immune response to normally harmless substances (allergens).Signs and Symptoms: Sneezing, hives, swelling, difficulty breathing.Diagnosis: Skin tests.Treatment: Antihistamines, immunotherapy, avoiding allergens.
Ganglios linfáticos poplíteos
HIV/AIDS
Physiology: Immune system infection by the HIV virus, which destroys lymphocytes.Signs and Symptoms: Fever, fatigue, opportunistic infections (AIDS).Diagnosis: Antibody/antigen tests and viral load testing.Treatment: Antiretroviral therapy (ART).

LUPUS
Physiology: Multisystem autoimmune disease causing inflammation and organ damage.Signs and Symptoms: Rashes, fatigue, joint pain, fever, kidney problems.Diagnosis: Lupus-specific antibodies, clinical history.Treatment: Corticosteroids, immunosuppressants.

HOME-CLASSWORK
Mucus, earwax, acid ph, saliva, sweat, tears, bait
Larger in children, and shrinks with ageT lymphocytes mature here
THYMUS
Antibody production
Skin, hair, mucous membranes (cilia)
Attacking the cell
Apoptosis: Suicide the sick cell
Microbiome (especially intestinal and genital tract)
Function: protect against infectionsBecause of the location, they are the first to encounter pathogens that try to enter the body through the nose and mouth
TONSILS
Function: hematopoiesisContains stem cells that produce all types of blood cells
BONE MARROW
Phagocytosis: Eat the pathogen
Macrophages inside the nodes help clean the lymph .Lymphocytes congregate when there is an infection .A larger-than-normal node can indicate the presence of pathogens
Function: to cleanse the bloodTwo partsWhite pulp: filters pathogens and debrisRed pulp: filters old red blood cells
