Plasma,
That are too large to pass through blood capillaries such as MACROPARTICLES from damaged areas and damaged cells from disease
Appearance of lymph
Colorless due to the lack of RBCs, might appear milky white.
Lymph vessels originate as…
Blind end tubes in interstitial spaces.
The walls of lymph vessels are more permeable to…
All interstitial fluid including proteins and cell debris.
The function of the cup shaped valves in lymp vessels…
One way movement, they prevent the back flow of lymph in vessels as it is transported back to the heart from the tissues.
Lymph vessels join together to form…
Two large ducts
1) Thoracic duct
2) Right lymphatic duct
Lymphatic vessels are absent from…
Bones, teeth, bone marrow, and CNS.
The 10 major trunks
(Named after the regions they drain)
Lumbar, jugular, subclavian, bronchomediastinal, intestinal
Left and right for each.
Lymphatic ducts are the…
Lymphatic vessels
The 2 ducts drain lymph into
Veins in the neck
The right and left subclavian veins at their junctions with the internal jugular veins.
A terminal lymphatic vessel located in the neck, anterior to scalene anterior muscle…
Right lymphatic duct
Duct responsible for draining lymph from the whole liver
Thoracic duct
Duct responsible for draining lymph from the upper surface of the liver
Right lymphatic duct
The right lymphatic duct is located…
Anterior to scalene anterior muscle.
The right lymphatic duct is formed by the union of 3 lymphatic trunks…
1) Right bronchomediastinal trunk
2) Right jugular
3) Right subclavian
Size of the right lymphatic duct…
1-2cm
