Lymphatic System Flashcards
what are the functions of lymphatic system
defense
liquid absorption
maintenance of fluid balance
what are the 3 groups of tonsils
pharyngeal tonsils
palatine tonsils
lingual tonsils
what are the 3 superficial aggregations of lymph nodes on each side of the body
inguinal nodes
cervical nodes
axillary nodes
functions of lymph nodes
activates immune system
remove pathogens from lymph (filters)
identify the pulp of the spleen:
lymphatic tissue surrounding the arteries within the spleen
white pulp
identify the pulp of the spleen:
associated with the veins that consists of a fibrous network, filled with macrophages and red blood cells
red pulp
spleen filters the _____
blood
functions of spleen
act as a reservoir for blood
filters blood
detect and respond to foreign substances in the blood
destroys old and damaged RBC
it is located in the superior mediastinum
thymus
it is located in the superior corner of the abdominal cavity
spleen
it is the site for maturation of T cells
thymus
thymus produces
T cells
the ability to resist damage from pathogens (microorganisms), harmful chemicals (toxins) and internal threats (cancer cells)
immunity
what are the 2 immunity system
innate
adaptive
identify the type of immunity system:
body recognizes and destroys pathogens
and the response improves each time the pathogen is encountered
adaptive immunity
identify the type of immunity system:
body recognizes and destroys certain pathogens and respond in the same each time the body is exposed
innate immunity
what are the 2 subdivisions of adaptive immunity
antibody-mediated immunity
cell-mediated immunity
what are the 4 adaptive immunity
physical barriers
chemical mediators
WBC
inflammatory response
antibody-mediated immunity involves ______
B cells
cell-meditated immunity involves _______
specific T cells
it is the ability of adaptive immunity to recognize a particular substance
specificity
it is the ability of adaptive immunity to “remember” previous encounters with a particular substance
memory
identify the innate immunity:
prevent pathogens and chemicals from entering the body
physical barriers
identify the innate immunity:
destroy pathogens or prevent their entry into the cells
chemical mediators
identify the innate immunity:
The most important cellular components of immunity
white blood cells
WBC is produced in the _________ and _______ and released into the blood
red bone marrow
lymphatic tissues
it is a group of more than 20 proteins found in blood plasma
complement
proteins that protect the body against viral infections
interferons
identify the phagocytic cells:
the ingestion and destruction of particles by cells (phagocytes)
phagocytosis
identify the phagocytic cells:
usually the first white blood cells to enter infected tissues from the blood
neutrophils
identify the phagocytic cells:
monocytes that leave the blood and enter tissues and appears in infected tissues after neutrophils
macrophages
identify the cells of inflammation:
it is a motile white blood cells that can leave the blood and enter infected tissues
basophils
identify the cells of inflammation:
non-motile cells in connective tissue
mast cells
identify the cells of inflammation:
recognize tumor cells or virus-infected cells and destroy target cells
natural killer cells
identify the cells of inflammation:
participate in inflammation associated with allergies and asthma
eosinophils
basophil and mast cells are derived from ______
red bone marrow
identify the cells of inflammation:
it is produced in bone marrow
natural killer cells
