"lymphatic system" AND anatomy
lymphatic system anatomy vessels nodes trunks ducts authoritative overview
A clearly labeled anatomical schematic of the human lymphatic system. Show a front-view human silhouette with arrows tracing lymph flow from blind-ended lymphatic capillaries in tissues to collecting lymphatic vessels with valves, regional lymph nodes, lymphatic trunks, the right lymphatic duct, thoracic duct, cisterna chyli, and their drainage into the right and left venous angles. Clearly show that the right upper quadrant drains to the right lymphatic duct and the rest of the body drains to the thoracic duct.
Flow of lymph
→ Blind-ended lymphatic capillaries
→ Collecting lymphatic vessels with one-way valves
→ Lymph nodes
→ Lymphatic trunks
→ Lymphatic ducts
→ Venous circulation at the venous angles, where the internal jugular and subclavian veins meet.
Main ducts
| Duct | Area drained | Opens into |
|---|---|---|
| Right lymphatic duct | Right side of head and neck, right upper limb, right thorax | Right venous angle |
| Thoracic duct | Both lower limbs, abdomen, pelvis, left thorax, left upper limb, left head and neck | Left venous angle |
