Lymphatic Load
protein, water, fat, cellular components
protein can only re-enter the blood via the lymphatic system
more protein is in blood vs. interstitial fluid/space (pulling water in since it is hydrophilic)
Lymph Capillary
basement membrane, endothelial cells, anchoring filament
ABSORB ONLY
Pre-collector
valves, smooth muscle
ABSORB & TRANSPORT
deep one perforate fascia
Collector
passive valves (uni directional), lymphangion (respond to stretch and pull),
Lymphangiogenesis can occur epi-fascial
TRANSPORT ONLY
Nodes
create lymphocytes, trap foreign matter, learn pathogens, regulate protein levels
afferent and efferent vessels (to node and away from nod to trunk)
Trunks
proximal to all nodes (go afferent towards them)
i.e. subclavian, mediastinal, lumbar, supraclavicular, jugular, intestinal
Ducts
lead to venous angles then pour pure fluid back into venous system
2 ducts: Thoracic & Right Lymphatic
Thoracic Duct
base = cisterna chyli (R/L lumbar & interstitial) goes to L venous angle
3/4 daily load
drains: LE's, pelvis, LUE, L trunk, L head/neck
Right Lymphatic Duct
Drains: RUE, R head/neck, R trunk
1/4 daily load
Territories
"root areas" go to the lymph nodes
Watersheds
Divide the territories
i.e. transverse, median-sagittal, clavicular, spine of scapula, chaps
