|
|
Primary Lymphatic Organs and location? |
Stem Cells divide, red bone marrow, thymus |
|
|
Secondary lymphatic system and location? |
Immune responses occur, lymph nodes, spleen, lymphatic nodules |
|
|
What is the route taken by the secondary lymphatic system |
Capillaries - Vessels - Nodes - Trunks - Ducts |
|
|
Name the organs that lack capillaries |
avascular, CN, spleen, red blood marrow |
|
|
Where are capillaries located? |
Instersticial space, surrounded by endothelium cells, one end closed, anchored by filaments |
|
|
How do lymphatic cappilaries work? |
More permeable and larger diameter, overlapping ends seperate under high pressure, absorbs proteins and lipids |
|
|
What are anchoring filaments? |
elastic fibers that extend into surrounding tissue and pull to further open capillary openings when tissues swell |
|
|
Lymphatic Vessels location and layout? |
subcantaneus tissue, thinner walls and more valves than veins, viserca forms plexuses around arteries |
|
|
Route of lymph flow? |
Afferent, subscapular, trabecular, medullary, efferent, hilum |
|

mediastinum, between sternum and aorta. trabeculae, lobules, cortex. T Cells mature and proliferate here |
|
|
Where is the spleen located? Composure? |
Left hypochondriac region, between stomach and diagphram. Hilum, spleen artery and vein, efferent lymphatic vessels and nerves |
|
|
Where are nodules located? Name tonsils? |

What is the medulla composed of? |
Base facing cortex, papilla towards hilum |
|
|
Path of urine drainage |
collecting duct, minor calyx, major calyx, renal pelvis, ureter bladder |
|
