Lymphatic System Flashcards
name the 6 lymphatic tissue
- lymph nodes, spleen, bone marrow, thymus, lymphoid nodules, tonsils
Name the location of the lymph nodes
- everywhere, but clustered in cervical, axillary, mammary, and inguinal regions
What does the lymph nodes do?
filtering body that filters lymph
Name the location of the spleen
upper left side of your abdomen, next to your stomach, and behind your left ribs
What does the spleen do?
contains macrophages and dendritic cells to remove debris, pathogens, and dying erythrocytes
Name the location of the bone marrow
In the center of the bone
Name the location of the thymus
in the chest, between the lungs and behind the sternum
What does the thymus do?
matures white blood cells called T lymphocytes
Name the location of the Lymphoid nodules
located in respiratory and digestive tracts (increased risk of exposure)
Where is mucosa-associated lymphoid tissue (MALT) located
gastrointestinal tract, breast tissue, lungs, eyes, and small intestine
where is Bronchus-associated lymphoid tissue (BALT) located
bronchi, between bronchi and arteries
Name where the tonsils are located
-Pharyngeal, palatine, lingual
Pharyngeal tonsil location
back of throat
palatine tonsil location
either side of throat
lingual tonsil location
base of tongue
movement of Lymph
- lymph only moves in one direction, towards the heart
- movement due to movements of body, contraction of skeletal muscles, and breathing
Function of lymphocytes
they are white blood cells uniform in appearance but varied in function and include T, B, and natural killing of a virus- infected and tumor cells, and regulation of the immune response
Difference between cell mediated VS. humoral immunity
Cell mediated: T cell- dealing with fighting off viral-infected cells or abnormal cells
humoral immunity: B cells- dealing with fighting off any antigens outside of cells
Types of immunity
Active, Passive, Natural, Artificial
Active immunity
individual exposed to pathogen or antigen and produces his/her own antibodies, long- term protection
Natural active immunity
immunity gained through illness and recovery
Artificial active immunity
Immunity gained through vaccine
Passive immunity
individual receives antibodies made by someone else, short- term protection, no memory cell production
Natural passive immunity
Immunity gained from anti-bodies passed in breast milk or through the placenta
Artificial passive immunity
Immunity gained through anti-bodies harvested from another person or an animal
