First & second lines of defense |
|
Definition
Innate and nonspecific, always on guard. Do not improve with repeated exposure. Also involves inflammatory and phagocitic defenses |
|
|
Term
|
Definition
All about barriers. Physical (anatomical), chemical, and genetic. Physical: thick skin, cilia, mucus, secretions. Chemical secretions are anything; lysozyme in tears, hcl in stomach, seamen, sweat, skin's ph etc. Genetic; geneticly resistant to something (typically viruses) |

Term
|
Definition
Specific, acquired, T cells and B cells. |
|
|
Term
|
Definition
The study of all of the bodies 2nd and 3rd lines of defense. A healthy functioning immune system is responsible for: survellance of the body, recognition of foreign material, destion of entities deemed to be foreign. |
|
|
Term
|
Definition
Is identified by WBC's as they read "markers" on their surfaces, WBC's that ?? |
|
|
Term
Body compartments and communication |
|
Definition
Reticuloendothelial system (RES), extracellular fluid (ECF), blood stream, lymphatic system |
|
|
Term
Reticuloendothelial system |
|
Definition
Network of connective tissue fibers that provide a passageway between tissues and organs. Ex: Thymus, lymph nodes and spleen. Has Macrophages (WBC's) |
|
|
Term
|
Definition
Compartmentalized network of vessels cells and specialized acessory organs. Transport lymph through a system of vessels and lymph nodes. Primary functions include; returning ECF to circulatory system proper, act as a drain off system for inflammatory response, render survailence recognition and protection against foreign materials |
|
|
Term
|
Definition
Plasma- like liquid formed wwhen certain blood components move out of blood vessels into the extracellular spaces and diffuse into the lymphatic capilaries. Like plasma but no RBC's. |
|
|
Term
|
Definition
Similar to thin-walled veins, and run along the lines of blood vessels. High numbers in hands, feet, and nipples.Only flows in direction from extremities towards the heart. Lymph is moved by the contraction of skeletal muscles which lymphatic vessels wend their way through. |
|
|
Term
|
Definition
Thymus, spleen, lymoh nodes. |
|
|
Term
|
Definition
Small, encapsulated, bean shaped organs. Usually found in clusters along lymphatic channels and large blood vessels and thoracic and abdominal cavities. Major aggregations: axillary nodes, inguinal nodes, cervical nodes |
|
|
Term
|
Definition
Similar to lymph node but it filters blood instead of lymph. Filters pathogens from blood. |
|
|
Term
|
Definition
Originates in the embryo, high rates of activity and growth until puberty. Shrinks gradually through adulthood. Thymic hormones help thymocytes develop specificity to be released as mature T cells. |
|
|
Term
Miscellaneous lymphoid tissue |
|
Definition
Tonsils, breasts of lactating women, GALT (gut associated= appendix, lacteals, peyer's patches) MALT (mucosal) SALT (skin) BALT (bronchial) |
|
|
Term
Circulatory system & blood components |
|
Definition
Consists of circulatory system proper and lymphatic system. Whole blood- blood cells suspended in plasma. Serum- plasma without clotting factors. |
|
|
Term
|
Definition
92% water, hundreds of chemicals, proteins (albumin & globulins) immunochemicals, fibrogen (& other clotting factors), hormones, nutrients, disolved gases & waste products |
|
|
Term
|
Definition
Precursor stem cell in marrow. Differentiates into stem cells for blood cells and lymphoid cells |
|
|
Term
Stem cell for blood cells |
|
Definition
Differentiate into; erythroblasts (RBC's), Megakaryoblasts (platelets), myeloblasts (granulocytes & mast cells) monoblasts (monocytes, macrophages & dendrites) |
|
|
Term
|
Definition
Differentiate into lymphoblasts which differentiate into T and B cells. |
|
|
Term
|
Definition
|
|
Term
|
Definition
Granulocytes, most common, horse shoe nuclei. Phagocytoses bacteria- granules are digestive enzymes. First to arrive to immune response. |
|
|
Term
|
Definition
In bone marrow and spleen, attach and destroy eukaryotic pathogens, associated with inflammation and allergies. |
|
|
Term
|
Definition
Present in very low numbers in the body. Fuction is sismilar to epsinophils, localized basophils are mast cells, mast cells are important in allergic responses. |
|
|
Term
|
Definition
Specific immunity, 2nd most common in body, AGRANULOCYTES |
|
|
Term
|
Definition
Come out of bone marrow and survive as phagocytes for a few days and then they differentiate into macrophages. |
|
|
Term
|
Definition
Develop from stem cells in the bone marrow, loose nuclei before they get into circulation. Transport oxygen and co2 to and from tissues |
|
|
Term
|
Definition
Fragments of membrane. Formed elements in circulating blood. Function primarily in hemostasis and releasing chemicals for blood clotting and inflammation. |
|
|
Term
|
Definition
Inflammation, interferon, phagocytosis, compliment. Relatively nonspecific but do communicate with 3rd line |
|
|
Term
|
Definition
2nd line of defense. Classic signs & symptoms; rubor, calor, tumor, dolor & loss of function. Main function is to immune components to the site of injury, set in motion tissue repair & clear away harmful substances. Destroy microbes & block further invasion. |
