    00:01 So, now, let's just summarize the lymphatic drainage of the abdomen and pelvis.

    00:06 So, here we have the celiac lymph nodes which are going to receive lymph from the liver and gallbladder via the hepatic lymph nodes.

    00:12 We also have the pancreas and duodenum via the pancreaticoduodenal and pyloric lymph nodes.

    00:18 These will pass into the celiac lymph nodes of the stomach, the gastro-omental pyloric gastric lymph nodes pass up into the celiac.

    00:26 And the spleen via the pancreaticosplenic lymph nodes passing into the celiac lymph nodes.

    00:32 The superior mesenteric lymph is going to drain from the jejunum and ileum via mesenteric ileocolic lymph nodes.

    00:39 We then have the cecum, passing via the ileocolic.

    00:43 Here we have the middle colic and the mesocolic passing to the superior mesenteric lymph nodes.

    00:48 And then with the ascending colon, these are going to pass back to the superior mesenteric lymph nodes via the paracolic and right colic.

    00:56 If we then look at the inferior mesenteric lymph nodes, we can see the rectum its superior parts.

    01:01 We can also see the descending and sigmoid colon.

    01:04 These are all going to pass towards the inferior mesenteric lymph nodes.

    01:09 The kidneys and suprarenal glands, the ovaries and testes pass to lumbar lymph nodes, and the common iliac lymph nodes are going to receive the lower portion of the rectum and also going to receive the external and internal iliac lymph nodes which are taking from the uterus, the bladder, and also the ductus deferens, seminal vesicles, and the prostate within the male.

    01:30 These are passing by the internal iliac lymph nodes.

    01:34 The inferior mesenteric lymph nodes will pass up to the superior mesenteric lymph nodes, ultimately passing up to the celiac lymph node.

    01:43 All of these forming that intestinal lymphatic trunk.

    01:46 There'll be contributions from the common iliac, the lumbar lymph nodes on both the left and right side, forming those lumbar trunks which combined with the cisterna chyli.

    01:56 The cisterna chyli then gives rise to the thoracic duct that will pass up through the posterior mediastinum of the thorax and merging the junction between the internal jugular vein and the subclavian vein on the left hand side.

    02:09 So we can see it's a rarely complicated network of lymph nodes.

    02:12 But don't let that complication get in the way, essentially, visceral and parietal lymph nodes drain the respective organs.

    02:21 They will very much follow the arterial supply, especially basing that on embryological origin of that blood supply, and they'll ultimately all come back into this common intestinal trunk.

    02:32 The cisterna chyli than the thoracic duct.

    02:35 This is important than lymphatic drainage as it helps to consider movement of cancerous cells during the development of tumors.
