Veterinary lymphatic system Flashcards
Lymphatic system
systema lymphaticum
name 4 primary or central lymphoid tissues

name 3 cell tpes that populate secondary lymphoid organs
lymphocytes,
macrophages and
dendritic cells
name 5 secondary or peripheral lymphoid tissues
lymph nodes,
spleen,
mucosa associated lymphoid tissue (MALT-system),
tonsils,
regional lymphoid tissue etc
lymphatic system has what three functions
immune defence
removal of interstitial fluid from tissues
transport of fats
lymphangion definition
is the functional unit of a lymph vessel that lies between two semilunar valves.
Lymph vessels are channels larger than the lymph capillaries that have thicker walls, valves in their lumen and smooth muscles in their walls, thus lymph vessel lymphangion is muscular and capable of contracting on its own.
2 latin terms for lymph node
lymphonodus; nodus lymphaticus
translate and define lymphocentre

Car and Ru have rather large nodes,
eq has small nodes packeted together
translate lymph and describe its composition
lympha
the clear yellowish fluid, generally pale and
contains lymphocytes and proteins.
the lymph formed in the digestive system is called what and describe its composition
chyle, is rich in triglycerides (fat), and is milky white
lymphatic vessels

They converges on two or three large trunks that open into chylic cistern or major veins.
difference between lymph capillaries and lymph vessels other than size?
lymph capillaries are mainly responsible for the absorption of interstitial fluid from the tissues,
while lymph vessels propel the absorbed fluid forward into the larger collecting ducts
