t or f.... the lymphatic system has no pump or heart true
transports excess tissue fluid back into the circulatory system lymph vessels m
produces lymphocytes and filters out harmful bacteria lymph nodes
produces t-lymphocytes necessary for the immune system thymus gland
straw colored fluid similar in composition to blood plasma lymph
lymph fills the surrounding spaces between tissue cells, it is also referred to as.... interstitial fluid
lymph is composed of ... water lymphocytes some granulocytes oxygen digested nutrients hormones salts carbon dioxide urea
t or f.... lymph doesn't contain red blood cells or protien molecules true
accompany and loosely parallel the veins lymph vessels
specialized lymph vessels in the villi of the small intestine that absorb digested fats and transport them in to the circulatory system lacteals
lymph flows in to one of 2 large main lymphatics called.... thoracic duct and right lymphatic duct
thoracic duct is called left lymphatic duct
tiny, oval shapped structures ranging from the size of a pinhead to that of an almond lymph node
capsular extensions that divide the node into a series of compartments that contain lymphatic sinuses and lymphatic tissue are also called trabeculae
lymphatic vessels enter the node at various sites called afferent lymphatic vessels
lymph node surrounds the... which produces the lymphocytes germinal center
network of fibers macrophage cells
swelling in the lymphglands adenitis
under arms axillary nodes
masses of lymphatic tissues which are capable of producing lymphocytes and filtering bacteria tonsils
most common tonsils palatine
tonsils are located in the upper part of the throat are commonly known as adenoids
during childhood tonsils become infected, enlarged, swallowing severe sore throat tonsilitis
saclike mass of lymphatic tissue located near the upper left area of the abdominal cavity spleen
located in the upper anterior part of the thorax, above the heart thymus gland
enlargement of the lymph nodes lymphadenitis
form of cancerof the lymph nodes hodgkins disease
disease caused by the epstein-barr virus infectious mononucleosis
immunity which we are born natural
reaction that occurs as a result of exposure to these invaders... immunity that develops over a lifetime... passive or active acquired
is borrowed immunity... acuirred artificially by injecting antibodies passive acquired
preferable to passive immunity because it lasts longer active acquired
2 types of active acquired immunity natural-having recovered from a disease artificial -inoculated with suitable vaccine
increasing and individual's resistance to a particular infection by artificial means immunization
protien that functions specifically as an antibody immunoglobin
when a person's own immune system mistakenly targets the normal cells, tissues, and organs of a person's own bodies autoimmunity/ autoimmune disorder
disease that results in thickening of the skin and blood vessels scleroderma
occurs when the body's immune system fails to protect itself against foreign material hypersensitivity
