| Question | Answer |
|---|---|
| composed of lymph, lymph nodes, lymph vessels, the spleen, the thymus gland, lymphoid tissue in the insestinal tract, and tonsils | the lymphatic system |
| 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 |

| 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 |
| antigen that causes allergic responses | allergen |
| severe sometimes fatal allergic responses | anaphylaxis or anaphylactic shock |
| AIDS | auto immune deficiency syndrom |
