Question 1: lymph node components
Answer:
afferent lymphatic vessels, efferent vessels, and capsule enclosing node
Question 2: MALT
Answer:
located in gastrointestinal, respiratory, genital, and urinary tracts, found in lamina propria of the mucosa, helps defend against foreign substances, prominent in small intestines (especially ileum - large collections of lymphatic nodules)
Question 3: lymphatic system
Answer:
helps immune system defend body against infectious agents, transports and houses lymphocytes and other immune cells, and returns excess fluid to blood to maintain fluid balance
Question 4: cortex of the thymus
Answer:
has immature T-lymphocytes
Question 5: lymph nodes usually occur in...
Answer:
clusters receiving lymph from body regions (i.e. axillary lymph nodes in the armpit - receive lymph from breast, axilla, and upper limb, i.e. inguinal lymph nodes in groin - receive lymph from lower limb and pelvis)
Question 6: monitoring blood as it flows through the spleen (continued)
Answer:
travel through sinusoids of red pulp (is in contact with splenic cords of red pulp, macrophages here phagocytize bacteria and foreign debris and old and defective erythrocytes and platelets) and travels through venules and out splenic veins
Question 7: secondary lymphatic structures
Answer:
no involved in lymphocyte formation, house lymphocytes and other immune cells, provide site of immune response initiation
Question 8: splenic sinusoids
Answer:
permeable capillaries, so blood cells easily exiting and drain to small venules leading to splenic vein
Question 9: tonsils
Answer:
secondary lymphatic structures found in pharynx, help protect against foreign substances inhaled or ingested, contain lymphatic nodules
Question 10: secondary lymphatic structures include
Answer:
lymph nodes, spleen, lymphatic nodules, tonsils, and MALT
Question 11: each thymic lobe...
Answer:
is surrounded by connective tissue capsule and has an outer cortex and inner medulla (both with epithelial tissue)
Question 12: organs of the lymphatic system
Answer:
tonsils, lymph nodes, spleen, and lymphatic vessels
Question 13: red pulp
Answer:
contains erythrocytes, platelets, macrophages, and B-lymphoctes, cells housed in reticular connective tissue, forming splenic cords, and has splenic sinusoids, and platelet reservoir to recenter blood as needed
Question 14: capsule enclosing node
Answer:
subdivide node into compartments
Question 15: spleen characteristics
Answer:
largest lymphatic organ, located in left upper abdominal quadrant (lateral to left kidney and posterolateral to stomach), and supplied by the splenic artery and drained by the splenic vein
Question 16: primary lymphatic structures include
Answer:
red bone marrow and the thymus
Question 17: components of lymph
Answer:
water dissolved solutes and small amount of protein, sometimes cell debris, pathogens, or metastasized cancer cells
Question 18: lymph
Answer:
fluid transported within the lymph vessels
Question 19: lymphatic vessels
Answer:
larger structures formed from lymphatic capillaries, superficial vessels positioned adjacent to superficial veins, deep vessels next to deep arteries and veins
Question 20: MALT
Answer:
mucose-associated lymphatic tissue
Question 21: characteristics of lymph
Answer:
15% of fluid entering interstitial spaces not reabsorbed into capillaries (about 3 liters daily), termed lymph once inside lymph vessels, lymph transported through network of increasing larger vessels (lymphatic capillaries, vessels, trunks, & ducts)
Question 22: swollen lymph nodes
Answer:
become tender with infection, sign that lymphocytes proliferating and fighting infection, and can palpate swollen superficial lymph nodes
Question 23: primary lymphatic structures
Answer:
involved in formation and maturation of lymphocytes
Question 24: efferent vessels
Answer:
drains node, originates at involuted potion of node, hilum
Question 25: thymus
Answer:
function in T-lymphocyte maturation, quite large in infants and young children (grows until puberty and begins to regress and much replaced by adipose tissue), consists of two fused thymic lobes
Question 26: lymph node characteristics
Answer:
small, round, or oval, encapsulated structures, located along pathways of lymph vessels, and filter lymph and remove unwanted substances
