While medical science has in progress over the years, there are still some areas that solutions and complete cures are evading by being so complicated, due to other influencing factors that complicate treatment issues; the left colic flexure and the large intestine are two of the human anatomy features that have doctors in a fix finding cures for, though progress is certain with dedicated research. 

     The left colic flexure is the curve at the junction from the transverse and descending colon and is also called the Splenic flexure; doctors believe there to be 2 kinds of colic flexures at the transverse colon: the right one, near the liver, and the left one, near the spleen (also known as the flexure lienalis because of its location, near the left renal, and lower than the spleen.

     The left colic flexure is located near the large intestine and is an important organ that necessarily proper medical attention for optimal functioning, without which it can cause many other diseases to develop. 

      Extending of the ileocecal junction to an individual's anus, the large intestine is typically 1.5m long; it comprises 3 visible bands of longitudinal muscle fibers that are 5mm long on the surface, called taeniae Colic. These begin at the base of the appendix and go way down to the cecum, extending right down to the rectum; it has tags of peritoneum filled with fat called epiploic appendages in its side besides sacculations called haustra, which make the large intestine a distinct part of the intestinal tract. 

     The cecum, ascending, descending, transverse and sigmoid colon besides the rectum, anal canal, and anus make up the large intestine, from which the first part is the most important. This is because the Cecum, 6cm long, is a blind cul-de-sac lying at the right iliac fossa of an individual however is that part of the colon that is situated below the ileum opening to the colon (behind the abdominal wall and greater omentum) where frequent peritoneal recess is present. 

     About the closer examination, one can see the vermiform appendix opening into the cecum approximately 2cm below the ileocecal cavity and once the cecum is open, the doctor can identify and find the opening of the ileum into it, which is an opening typically surrounded by thickened muscle forming the ileocolic valve. so, even as the left colic flexure (or the splenic flexure, as it is medically referred to) does not play the cecum's impressive role, it still has a crucial part at play as a responsible organ of the human digestive system that requires proper medical attention.
