The ascending colon (colon ascendens) is 18-20 cm long. The position of the ascending colon is variable. Its posterior wall occupies the extreme right lateral position on the posterior wall of the abdominal cavity. The intestine is directed vertically upward, located first in front of the square muscle of the lower back, then in front of the right kidney located retroperitoneally. Near the lower (visceral) surface of the liver, the ascending colon forms a bend to the left and forward and passes into the transverse colon. This is the right (hepatic) flexure of the colon (flexura coli dextra).
