- Pre-aortic nodesNodi preaorticiLymph nodes lying on the front of the abdominal aorta around the origins of its three unpaired gut arteries.
- Precaecal nodesNodi precaecalesA few small lymph nodes in front of the caecum, set along its anterior artery in the vascular fold of the caecum.
- Precaval nodesNodi precavalesLumbar lymph nodes lying on the anterior surface of the inferior vena cava, behind the peritoneum of the posterior abdominal wall.
- Prevesical nodesNodi prevesicalesSmall lymph nodes in the retropubic space, between the front of the urinary bladder and the back of the pubic symphysis.
- Proper hepatic arteryArteria hepatica propriaThe continuation of the common hepatic artery beyond the gastroduodenal branch, climbing in the lesser omentum to divide at the porta hepatis.
- Pubo-analis muscleMusculus puboanalisThe pubo-analis is a band of levator ani fibres that runs from the pubis back to the anal canal, blending with its sphincters.
- Pubococcygeus muscleMusculus pubococcygeusPubococcygeus is the main front part of levator ani, running from the back of the pubis to the coccyx in the pelvic floor.
- Pulmonary trunkTruncus pulmonalisThe short, wide artery leaving the right ventricle that carries deoxygenated blood towards the lungs before dividing into the two pulmonary arteries.
- Pyramidalis muscleMusculus pyramidalisPyramidalis is a small triangular muscle low on the front of the abdomen, lying in front of rectus abdominis inside its sheath.
- Rectus abdominis muscleMusculus rectus abdominisRectus abdominis is a long paired strap muscle lying either side of the midline in the front abdominal wall.
- Retro-aortic nodesNodi retroaorticiA few lumbar lymph nodes hidden behind the abdominal aorta, on the third and fourth lumbar vertebral bodies below the cisterna chyli.
- Retrocaecal nodesNodi retrocaecalesSmall lymph nodes behind the caecum, set along the posterior caecal artery in the right iliac fossa.
- Retrocaval nodesNodi retrocavalesLumbar lymph nodes lying behind the inferior vena cava, on the right psoas and the lumbar vertebral bodies.
- Right ascending lumbar veinVena lumbalis ascendens dextraA longitudinal vein on the right side of the lumbar vertebrae that connects the lumbar veins and ends by forming the azygos vein.
- Right atriumAtrium dextrumThe upper right chamber of the heart, receiving blood returning from the body and passing it through the tricuspid valve to the right ventricle.
- Right brachiocephalic veinVena brachiocephalica dextraA short, almost vertical vein behind the right sternoclavicular joint that meets its left partner to begin the superior vena cava.
- Right colic arteryArteria colica dextraA colic offshoot of the superior mesenteric artery, running rightwards on the posterior abdominal wall to feed the ascending colon and its flexure.
- Right colic nodesNodi colici dextriLymph nodes behind the peritoneum of the right flank, set along the right colic artery and draining the ascending colon.
- Right colic veinVena colica dextraA vein behind the peritoneum on the right of the abdomen that drains the ascending colon into the superior mesenteric vein.
- Right coronary arteryArteria coronaria dextraThe coronary artery arising from the right aortic sinus and running in the right atrioventricular groove round to the back of the heart.
- Right gastric nodesNodi gastrici dextri caudalesLymph nodes in the lesser omentum above the pylorus, set along the right gastric artery on the lower lesser curvature of the stomach.
- Right gastro-omental nodesNodi gastroomentales dextriLymph nodes in the greater omentum along the right gastro-omental artery, on the lower half of the greater curvature of the stomach.
- Right gastro-omental veinVena gastroomentalis dextraA vein of the greater omentum that follows the stomach's greater curvature towards the pylorus and ends in the superior mesenteric vein.
- Right inferior pulmonary veinVena pulmonalis dextra inferiorThe lowest vein of the right lung root, carrying oxygenated blood from the right lower lobe into the left atrium.
