|
|
||||
|---|---|---|---|---|---|
| show | a network of vessels that assist in circulating fluids. closely associated with the cardiovascular system
🗑
|
||||
| show | transports excess fluid away from the interstitial spaces, and returns it to the bloodstream. absorbs lipids from digestive system and transports them to the bloodstream. defends the body disease
🗑
|
||||
| show | refers to the fact that many cells of the lymphatic system provide both defense against disease and permanent immunity against future infections
🗑
|
||||
| show | lymphatic capillaries-lymphatic vessels-lymph nodes-larger lymphatic vessels-lymphatic trunks-lymphatic collecting ducts-veins in thorax
🗑
|
||||
| show | lymphatic capillaries that absorb fats, and transport them to the blood
🗑
|
||||
| lymphatic capillaries- | show 🗑
|
||||
| lymphatic vessels- | show 🗑
|
||||
| show | endothelial lining (inner), smooth muscle (middle), connective tissue (outer)
🗑
|
||||
| lymphatic trunks- | show 🗑
|
||||
| lymphatic collecting ducts- | show 🗑
|
||||
| tissue fluid formation- | show 🗑
|
||||
| show | has about the same composition as blood plasma. contains water and dissolved nutrients, gases, hormones. exception: tissue fluid does not contain large plasma proteins
🗑
|
||||
| lymph flow- | show 🗑
|
||||
| lymph flow muscle activity- | show 🗑
|
||||
| show | prevent backflow
🗑
|
||||
| roles of lymphatic capillaries- | show 🗑
|
||||
| lymphatic tissue contains several cell types- | show 🗑
|
||||
| mucosa-associated lymphoid tissue (MALT)- | show 🗑
|
||||
| show | consist of encapsulated lymphatic tissue. lymph nodes, thymus and spleen
🗑
|
||||
| show | usually bean-shaped, <2.5 cm long. located along lymphatic vessels; filter pathogens from lymph. contain lymphocytes and macrophages to fight invading pathogens
🗑
|
||||
| show | found in groups or chains along the paths of the larger lymphatic vessels throughout the body. NOT found in central nerous system
🗑
|
||||
| 2 primary functions of lymph nodes- | show 🗑
|
||||
| show | along with red bone marrow, the lymph nodes are centers for lymphocyte production. lymphocytes attack various pathogens in lymph nodes. macrophages engulf and digest foregin substances, damaged cells, debris
🗑
|
||||
| thymus- | show 🗑
|
||||
| show | large in infancy and early childhood. shrinks at puberty. small in and adult. in elderly, lymphatic tissue is replaced by adipose & other connective tissue
🗑
|
||||
| show | largest lymphatic organ. located in the upper left part of abdominal cavity. filters blood, like lymph nodes filter lymph- removes pathogens and damaged RBC's from blood
🗑
|
||||
| spleen contains 2 tissue types- | show 🗑
|
||||
| pathogens- defense against infections | show 🗑
|
||||
| innate (nonspecific) defenses: defense against infections | show 🗑
|
||||
| adaptive (specific) defenses: defense against infections | show 🗑
|
||||
| fever- non-specific (innate) defense | show 🗑
|
||||
| show | resistance to particular pathogens or to their toxins or metabolic by products. immune response is based on the ability to distinguish molecules that are part of the body "self" from "non-self"
🗑
|
||||
| show | membrane molecules that can elicit an immune response. adaptive responses are carried out by lymphocytes and macrophages that can recognize specific antigens
🗑
|
||||
| show | cellular immune response (performed by immune cells)
humoral immune response (performed by antibodies)
🗑
|
||||
| show | mucus, stomach acid, fever, inflammation, NK cells
🗑
|
||||
| adaptive- cell-mediated response | show 🗑
|
||||
| adaptive- humoral response | show 🗑
|
||||
| show | created in bone marrow, specialize in thymus. after release from thymus, make up 70-80% of circulating lymphocytes. some T cells settle in lymphatic organs, such as lymph nodes, spleen
🗑
|
||||
| show | after release from bone marrow, make up 20-30% of lymphocytes in blood. settle in lymphatic organs, along with T cells. abundant in lymph nodes, spleen, bone marrow, intestinal lining
🗑
|
||||
| show | activate other cells, help B cells product antibodies
🗑
|
||||
| cytotoxic cells- | show 🗑
|
||||
| memory T cells- | show 🗑
|
||||
| celllular immune respone- | show 🗑
|
||||
| humoral immune response- | show 🗑
|
||||
| show | Y-shaped proteins, composed of 4 amino acid chains. each type of antibody has unique conformation, making it specific for its antigen
🗑
|
||||
| show | react to antigens in several ways. agglutination. chemotaxis- attract macrophages/neutrophils, lysis- causes rupture of pathogen cell membrane, inflammation- prevent spread of antigens
🗑
|
||||
| show | produced by first encounter with antigen; first antidodies appear 5-10 days, and remain for several weeks; memory B cells are also produced
🗑
|
||||
| secondary immune response- | show 🗑
|
||||
| naturally acquired- | show 🗑
|
||||
| artifically acquired- | show 🗑
|
||||
| passive immunity- | show 🗑
|
||||
| active immunity- | show 🗑
