Lymphatic System Flashcards
Lymphatic fluid and where it is derived from
Lymph derived from interstitial fluid
Where are lymphatic capillaries not found
Bone marrow and avascular tissues (epithelia and cartilage)
CNS
Where is lymph found
Lymphatic capillaries
Function of lymphatic capillaries
Connect arteries and veins
Lymph in small intestines
Called Chyle
Why is lymph called chyle in SI
Chylomicrons (protein coated lipid droplets)
What are lymphatic capillaries called in SI
Lacteal
How are lymphatic vessels different from small veins
Have semilunar valves which prevent backflow
What generates the movement of lymph in lymphatic vessels
Indirect action of adjacent structures
Where do capillaries leave at lymph nodes
Hilum
Lymphatic organs
Primary- bone marrow and thymus
Secondary- spleen, tonsil and MALT
Lymph nodes
Cervical (IJV)
Axillary
Tracheal
Deep
Pericranial ring
Inguinal
Femoral
What do lymphatic vessels form
Trunks or ducts
Where do vessels drain to
Venous drainage in the neck
Venous drainage in the neck
IJV joins subclavian to form branchiocephalic vein
Where does thoracic duct carry lymph from
Two lower limbs,left upper limb, left thorax,left side of head and neck,abdomen
Where does thoracic duct receive lymph
Cristerna chyli
Origin of thoracic duct
Ascends through abdomen,pass through diaphragm
Ascends through thorax,lies more on the left
Enters vs between left IJV and left subclavian to form left branchiocephalic
