Chapter 6: Lymph & Immune Flashcards
Functions of the lymphatic system
(1) network of vessels that picks up excess tissue fluid, cleanses, and returns it to the circulatory system, (2) picks up fat absorbed by the digestive system
Functions of immune system
fights disease/infections
Organs of the lymphatic system
(1) lymph nodes, (2) lymphatic vessels, (3) thymus gland, (4) spleen, (5) tonsils

one
Network of vessels throughout the body that transports lymph
lymphatic vessels
These house lymphocytes & antibodies, remove pathogens, trap & destroy cells; located along the route of lymphatic vessels
lymph nodes
Organ in the LUQ that destroys old RBC, recycles iron & stores blood
Spleen
Gland essential for immune development
thymus gland
This acts as a physical filter to protect the body from disease/infection
tonsils
Lymph node in the armpits that drains fluids from the arms
axillary
Lymph node in the neck that drains fluid from the head and neck
cervical
Lymph node in the groin that drains fluid from the legs and pelvis
inguinal
Lymph node in the chest that drains fluid within the chest
mediastinal
Body’s ability to defend itself against pathogens (bacteria, viruses, fungi, protozoans, toxins, cancerous tumors
immunity
Non-specific immunity that does not require prior pathogen exposure
natural immunity
Immunity triggered by the body’s response to a specific pathogen; may be passive or active
acquired immunity
Type of acquired immunity that results when a person receives protective substances produced by another human/animal (ex. maternal antibodies, antitoxin)
passive acquired immunity
Type of acquired immunity that develops following a direct exposure to a pathogen; stimulates immune response (ex. vaccinations)
active acquired immunity
Disease-causing agents that stimulate an immune response
antigens
Two processes of the immune response
(1) humoral immunity aka antibody-mediated immunity, (2) cellular immunity aka cell-mediated immunity
Infections acquired in the hospital
nosocomial infection
Infection acquired from another person
cross infection
Infection acquired more than once by the same pathogen
reinfection
Infection acquired from one part of the patient’s body that spreads to another part
self-inoculation
lymphatic
pertaining to the lymph
splenic
pertaining to the spleen
