To eat
-toxic
Pertaining to poison
Lacteals
Lymphatic vessels at small intestines, absorb fats from diet
Lymphatic vessels
Conduct lymph from tissue toward thoracic cavity, one-way pipes; low pressure so have valves
Lymph nodes
Aka lymph glands, Small organs that filter bacteria/foreign organisms from body fluids
Spleen
Filters microorganisms, and old red blood cells from blood
Thymus gland
Assists body with immune function; develop antibodies; secretes hormone thymosin that changes lymphocytes to T cells
Tonsils
Combat to micro organisms, entering body through those arouse
Lymph
Excess tissue fluid from the body that has been returned to the circulatory system via a lymphatic vessel
Lymphatic capillaries
Smallest lymph vessels
Lymphatic ducts
Includes right lymphatic duct (drains, right arm, and right side of head, neck, and chest ) and thoracic duct (drains entire body, except for right arm, chest and lungs), two largest vessels in lymphatic system,
Sites for lymph nodes
Axillary, cervical, Inguinal, mediastinal
Three sets of tonsils:
Palatine, Pharyngeal (adenoids), Lingual
Blood sinuses
Spread out blood vessels within the spleen, resulting in slow moving blood flow
Thymosin
Hormone from thymus gland causes lymphocytes to change into T lymphocytes
T lymphocytes
Type of lymphocyte involved with producing cells that physically attack and destroy pathogens
Natural immunity
Immunity, not specific to a particular disease, doesn’t require prior exposure to the pathogen, a.k.a. innate immunity
Acquired immunity
Protective response of body to a specific pathogen 
Passive acquired immunity
Results when person receives, protective, substance produced by another human, or animal, example, maternal antibodies
Active acquired immunity
Follows direct exposure to pathogenic agent, example chicken pox. Immunizations are also special kind of active acquires immunity.
Antigen
Substance capable of inducing formation of antibody
Pathogen
Microscopic organisms capable of causing disease
Humoral immunity
Response to antigens by producing antibodies, also called antibody-mediated immunity.
Produces B lymphocytes/B cells, which produce the protective protein called an antibody/immunoglobulin
Cellular immunity
Results in production of T cells and natural killer cells that directly attached to foreign cells, immune response, fights invasion, aka cell-mediated immunity.
Defense cells are cytotoxic - they physically attack and destroy pathogenic cells
Antigen – antibody complex
When antibodies combine with antigen, either targets foreign substance for phagocytosis, or prevents the infectious agent from damaging healthy cells
Nosocomial infection
Infection acquired as a result of Hospital, exposure, a.k.a. healthcare – associated infection
Self inoculation
When person becomes infected in different part of body, by pathogen from another part of body
Occupational safety and health administration – OSHA
Issued mandatory guidelines to ensure employees at risk of exposure to bodily fluids are provided with personal protective equipment

Thymic
Pertaining to tonsils
Tonsillar
Lymphedema
Edema in extremities due to obstruction of lymph flow
Urticaria
Severe itching and hives
Elephantiasis
I’m inflammation/obstruction/destruction of lymph vessels, results in enlarged tissues due to edema
Hodgkin’s disease
Cancer of lymphatic cells
Lymphadenitis
Inflammation of lymph nodes
Lymphangioma
Tumor in lymphatic vessel
Mononucleosis
Disease w large amount of abnormal mononuclear lymphocytes
Non-hodgkin’s lymphoma
Other cancer of lymphatic tissues
Acquired Immunodeficiency Virus (AIDS)
Disease w defect in cell-mediated immunity systems
Human Immunodeficiency Virus (HIV)
Virus that causes aids, retrovirus
Multiple myeloma
Bone marrow tumor
Sarcoidosis
Autoimmune disease, fibrous lesions on lymph nodes
Severe Combined Immunodeficiency Syndrome
Children born w/o functioning immune system
