Lymphatic System Basics
The body's internal protective barrier to disease.
This procedure can lessen the risk of lymph edema by reducing the number of resected nodes.
What is a sentinal lymph node biopsy?
These nodes lie close to the skin surface.
What are superficial lymph nodes?
This is a transparent, colorless fluid largely composed of lymphocytes.
What is lymph?
This is the largest conveyor of lymph in the body.
What is the thoracic duct?
This type of cancer spreads primarily via the lymphatic system.
What is carcinoma?
What are muscle contractions?
This is the dialated origin of the Thoracic duct.
What is the Cisterna Chyli?
These are the 2 types of lymphocytes formed in the bone marrow before birth.
What are B-cells and T-cells?
The thoracic duct starts here and ends here.
What is L2 and the junction between the left subclavian vein and the left internal jugular vein.
This nodal group is comprised of approximately 20-30 nodes on each side of the body.
What are the axillary nodes?
These nodes drain areas from within the deep fascia.
What are deep lymph nodes?
These trunks receives lymph from the lower limbs, the walls and viscera of the pelvis, the kidneys, the suprarenal nodes & the deep lymphatics of the abdominal wall
What is the Rt and Lt lumbar trunks?
These stay within the bone marrow until mature and then spread throughout the body, concentrating in the spleen and lymph nodes.
What are B cells?
This receives lymph from the Rt side of head, neck & thorax Rt upper limb, Rt lung & Rt side of heart Diaphragmatic surface of the liver.
What is the right lymphatic duct?
Most nodes are approximately this big.
What is 2 - 30 mm?
Nodes of have many of these vessels entering the node, but only one of these vessels exiting the node.
What are afferent and efferent vessels?
This trunk receives lymph from the stomach, intestine, pancreas, spleen & the visceral surface of the liver
What is the intestinal trunk?
These leave the bone marrow and mature in the thymus.
What are T cells.
These trunks (right & left) drain the head &
neck with the exception of the skin at the
lower part of the back of the neck.
What are the jugular trunks?
These are the 3 main functions of the lymphatic system.
What is draining and filtering interstitial fluid, transporting fats, and immunity?
Efferent vessels unite to form these.
What are lymph trunks?
The lumbar and intestinal trunks both feed into this.
What is the thoracic duct?
Lymphocytes are found in these three anatomic areas.
What are lymph nodes, the spleen, and bone marrow?
These are the other organs considered part of the lymphatic system.
What are the tonsils, thymus, peyers patches, and spleen?
