The human body one structure at a time. Every page has a 3D model you can turn, with its parts numbered on it, where it sits, what it does and what supplies it.

- Coeliac trunkTruncus coeiiacusThe first unpaired branch of the abdominal aorta, a short trunk just below the diaphragm that supplies the organs of the upper abdomen.
- Colic branch of ileocolic arteryRamus colicus arteriae ileocolicaeThe upward branch of the ileocolic artery that climbs on the beginning of the ascending colon to join the right colic artery.
- Common hepatic arteryArteria hepatica communisA short branch of the coeliac trunk that runs to the right along the pancreas and divides into the proper hepatic and gastroduodenal arteries.
- Common iliac arteryArteria iliaca communisOne of the paired terminal branches of the abdominal aorta, running down to the pelvic brim to divide into external and internal iliac arteries.
- Common iliac veinVena iliaca communisA short paired vein of the lower abdomen, formed anterior to the sacroiliac joint, that joins its partner to make the inferior vena cava.
- Coronary sinusSinus coronariusA wide venous channel in the posterior atrioventricular groove that gathers most of the heart's own venous blood and empties into the right atrium.
- Costocervical trunkTruncus costocervicalisA short branch from the back of the subclavian artery that arches over the dome of the pleura to the first rib's neck.
- Cystic nodeNodus cysticusA lymph node at the neck of the gallbladder, beside the cystic duct and cystic artery.
- Descending branch of left colic arteryRamus descendens arteriae colicae sinistraeThe lower branch of the left colic artery, running down behind the peritoneum to the descending colon and the sigmoid arteries.
- DiaphragmDiaphragmaThe diaphragm is the dome-shaped sheet of muscle and tendon separating the chest from the abdomen, and the chief muscle of breathing.
- External abdominal oblique muscleMusculus obliquus externus abdominisThe external oblique is the outermost and largest flat muscle of the side and front of the abdominal wall.
- External anal sphincterSphincter externus aniThe external anal sphincter is the ring of voluntary skeletal muscle around the lower anal canal that keeps the anus closed.
- External iliac arteryArteria iliaca externaThe larger terminal branch of the common iliac artery, following the pelvic brim to pass under the inguinal ligament as the femoral artery.
- External iliac veinVena iliaca externaA paired pelvic vein continuing the femoral vein from the inguinal ligament along the pelvic brim to the front of the sacroiliac joint.
- External intercostal musclesMusculi intercostales externiThe external intercostals are the outermost layer of muscle filling each space between neighbouring ribs, used mainly in breathing in.
- First posterior intercostal arteryArteria intercostalis posterior primaThe artery of the first intercostal space, given off by the supreme intercostal artery rather than by the aorta.
- Gastroduodenal arteryArteria gastroduodenalisA short artery behind the first part of the duodenum, normally a branch of the common hepatic artery, feeding the pylorus, duodenum and pancreatic head.
- Great cardiac veinVena magna cordisThe largest tributary of the coronary sinus, climbing the anterior interventricular groove and curving left round the heart to its back.
- Hemi-azygos veinVena hemiazygaA vein beside the lower thoracic spine on the left that drains the lower left chest wall and crosses the midline to join the azygos.
- Hepatic portal veinVena portae hepatisThe short, wide vein that carries blood from the gut, spleen, pancreas and gallbladder into the liver, formed at the pancreatic neck.
- Hepatic veinsVenae hepaticaeThe valveless veins that carry blood out of the liver and open directly into the inferior vena cava behind it.
- Ileal branch of ileocolic arteryRamus ilealis arteriae ileocolicaeAn offshoot of the ileocolic artery that runs along the terminal ileum in the lower right abdomen, supplying the last part of the small intestine.
- Ileocolic arteryArteria ileocolicaThe last branch of the superior mesenteric artery, running to the right iliac fossa to supply the terminal ileum, caecum and appendix.
- Ileocolic nodesNodi ileocoliciLymph nodes along the ileocolic artery, draining the terminal ileum, caecum, appendix and start of the ascending colon.
