The liver and spleen are seen in the upper abdomen (coloured blue). The liver extends quite low in the abdomen, but this can be a normal variant (Riedel's lobe). The liver doesn't usually extend below the lower pole of the right kidney.
Both kidneys can also be demonstrated (yellow) and are held away from the spine by the psoas muscle.
The right colon (ascending colon) is filled with faeces, but can be traced over the midline to the splenic flexure and then down the left flank towards the pelvis.
