CH 6 The Lymphatic and Immune System Flashcards
A Large collection of lymph nodes located in the axilla ( Armpit)
Axillary Nodes
One of two types of specific immunity that exist in the body, it is primarily mediated by B cells; also called humoral immunity
Anitbody-Mediated ( humoral) Immunity
One of two types of specific immunity that exist in the body, it is primarily mediated by T-Cells
Cell-Mediated Immunity
Large collection of lymph nodes located in the neck
Cervical Nodes
Tissue with no clear boundary that blends with surrounding tissue and contains lymphocytes and other cells
Diffuse Lymphatic tissue
A Large collection of lymph nodes located in the groin
Inguinal Nodes
One of three sets of lymphatic organs that comprise the tonsils, they are located on the posterior margin of the tissue and help protect the body from bacteria introduced into the mouth and nose
Lingual Tonsils
Round or bean-shaped structure interspersed along the course of the lymph vessels, which filter the lymph and serve as a source of lymphocytes
Lymph Nodes
Tissue that is denser than diffuse lympathic tissue, found in the loose connective tissue of the digestive, respirtyory, and urinary system
Lymph Nodules
Thin-walled vessels through which lymph circulates through the body, they travel close to the major arteries and veins
Lymph vessels
One of two great lymph vessels, it empties into the subclavian vein
Lymphatic Duct
A passive circulatory system that transports a plasma-like liquid called lymph, a thin fluid that bathes the tissues of the body
Lymphatic System
A type of white blood cell that helps fight infection that provide immunity
Lymphocytes
Cells that leave the bloodstream and enter diseased tissue after the neutrophils and are responsible for the later stage of fighting infectione, including the disposal of dead bacteria
Macrophages
The spreading of disease from one part of the body to another, especially with man forms of cancer
Metastasize
Immune response that is predictable each time the bod is exposed to particular challenge
Nonspecific Immunity
One of three sets lymphatic organs that comprise the tonsils. They are located in the back of the throat, on each side of the posterior opening of the oral cavity, and help protect the body form bacteria introduced into the mouth and nose
Palatine Tonsils
The process of ingesting and destroying foreign matter by certain types of leukocytes
Phagocytosis
One of three sets of lymphatic organs that comprise the tonsils, they are located near the internal opening of the nasal cavity and help protect the body from bacteria introduced into the mouth and nose. Also called adenoids
Pharyngeal Tonsils
The immune response to given substance that is faster and stronger after each subsequent exposure
Specific immunity
An organ of the lymphatic system that is located in the left upper quadrant of the abdomen and consists of two types of lymph tissue: (Red Pulp; (venous drainage) and White Pulp (arterial drainage). that are associated with drainage of the spleen
Spleen
A triangular- shaped gland located below the sternum in the superior mediastinum that produces lymphocytes ( Large in infants, shrinks at we get older.)
Thymus
A response of the immune system that results in the influx of cells and other chemicals to fight a foreign challenge.
the most common chemicals are histamin, kinins, complement,prostaglandines, leukotrienes, pyrogen, and interferon
Inflammatory Response
Prevents back flow through the vessels
Valves
Has to passe through at least one to return back the bloodstream
Lymph Node
Are the most important component of the immune system
Leukocytes
these are also called nodes
Glands
Comprised of 80% to 85% of total serum antibody and is responsible for numerous actions: ex Rh antigens that destroy the fetus
IgG
Common means of disease transmission form person to person
Air born, body substance , injection , and oral transmission
Infectious disease that is spread through droplets from coughing and sneezing ( prevalent in nursing homes, homeless shelters, hospitals, prisons, migrant farms, IV drug users.
Tuberculosis (TB)
Bacteria
UTI
Viruse
AIDS, Common Cold
Fungi
Athletes Foot, Valley fever
Protozoans
Malaria
Nematodes
Anal itch
prions
Mad cow, strep throat
Certain body sites are normally colonized by various bacteria. Help keep homeostasis. Located in the gastrointestinal tract
E Coli
Genetic or natural passive immunity results when antibodies produced by the mother cross the placenta barrier to provide protection against fetal infections
Natural Immunity
Develops in one’s life time and is a reaction in the body occuring as a result of natural exposure to invaders or from a deliberate exposure to an antigen
Acquired Immunity
Frequent infections diseases in the prehospital setting
Pneumonia and hepatitis
