Lymphatics Flashcards
What part of the body does the right lymphatic duct receive lymph from? Where does it drain?
RUQ
Right side of: head, neck, thorax, upper limb
Enters the right venous angle (junction of the right internal jugular and R subclavian vein)
What is the cisterna chyli? What does it give rise to?
Dilated collecting sac at L1/L2
Drains lower body lymph
Turns into thoracic duct
What are notable locations of lymph nodes in the chest wall and what areas do they drain?
Parasternal (along internal thoracics, drains medial 1/2 of breast)
Intercostal (posterior end of intercostal spaces)
Diaphragmatic (around periphery of superior surface of diaphragm)
What are the lymphatics of the mediastinum?
Trachea and bronchial (Pulmonary, brachiopulmonary, tracheobronchial)
Posterior mediastinal (posterior to pericardium)
Anterior mediastinal (thyroid, thymus, ant. pericardium) Allow cancers to spread to abdomen
What are the lymph nodes of the abdomen?
Pre-Aortic (celiac, SMA, IMA) Pre = on top of
Para-Aortic. Para = on the side of
What is MALT tissue?
Mucosa Associated Lymphoid Tissue
Non-encapsulated lymphoid tissue in the mucosa/submucosa of GI, respiratory, UG
What are Peyer’s Patches?
Lymphoid clusters in the lamina propria of the ileum
B&T cells, macrophages, plasma cells
What are the lymphatics of the pelvis?
External iliac
Internal iliac
Sacral
Common iliac
What cancers will spread to pre-aortic lymph nodes?
Stomach Liver Spleen Pancreas Intestines
What cancers will spread to para-aortic lymph nodes?
Suprarenal
Kidney
Gonads
What is lymphangitis?
Inflammation of lymph vessels
What is lymphadenitis?
Inflammation of lymph nodes
What is Virchow’s node?
Enlarged lymph node in the left supraclavicular fossa
Receives blood from abdominal cavity, thus enlarged in cancers of the abdomen (usually gastric)
Where do most female breast cancers occur?
Upper outer quadrant (and thus axillary lymph nodes)
Where do most male breast cancers occur?
Central/medial, and thus drain into the sternal nodes
