Anatomy Lecture Deck 5 Flashcards
(484 cards)
T cells may attack blank cells or those infected by a blank
foreign, virus
T cells may stay on reserve only to become active if the blank reappears
pathogen
lymphocytes that are also derived directly from bone marrow and directly attack foreign cells
natural killer
reticular connective tissue is dominated by blank
lymphocytes
these are not organs but include mucosa associated lymphoid tissue (MALT)
lymphoid nodules
MALT has blank lymph nodules
digestive
lymph nodes are not the same as blank
nodules
MALT that is positioned around the pharynx and remove pahtogens that enter via air or food
tonsils
three types of tonsils
pharyngeal, palatine, lingual
tonsil with one nodule in nasopharynx like adenoids
pharyngeal
tonsil with two nodules on the soft palate
palatine
tonsils with two nodules at the base of the tongue
lingual
MALT that line mucosa of the small intestine
aggregated lymphoid nodules
MALT that is a blind tube at the beginning of small intestine and is an area that is prone to infection
appendix
appendix infected is called blank and allows the intestinal blank to enter underlying tissue
appendicitis, flora
these are surrounded by a fibrous connective tissue capsule and include lymph nodes, thymus, spleen
lymph organs
lymph organs that are bean shaped and lie between several blank and one blank vessel
lymph nodes, afferent, efferent
indented region where blood vessels, nerves, and efferent lymph vessels connect in lymph nodes
hilum
lymph nodes have a blank which has a capsule which has blank that subdivide it
cortex, trabeculae
two regions of lymph node cortex
outer, inner
region of lymph node cortex that consists of aggregated B cells
outer
region of cortex of lymph node that has T cells that enter blood here
inner
lymph node part where B cells leave
medulla
three locations of lymph nodes
cervical, axillary, inguinal, pelvic, abdominal, thoracic
