What Is Sigmoid Colon?
The sigmoid colon is a part of the large intestine that is closest to the rectum and anus. It gets its name from its shape – the Greek letter sigma (σ) resembles a question mark, and this is how the sigmoid colon looks when viewed from the front. The sigmoid colon is about two feet long. It connects the descending colon to the rectum.
The sigmoid colon is the last portion of the large intestine. It begins at the junction of the descending colon and extends to the rectum, where it joins with the anal canal. The sigmoid colon has a variable relationship to the pelvic floor. Occasionally, it can herniate, or protrude, through the pelvic floor into the pelvis.
Sigmoid colon, a terminal section of the large intestine that connects the descending colon to the rectum; its characteristic is to keep fecal wastes until they're geared up to go away the body. The sigmoid colon derives its call from the reality that its miles are curved in the form of an S (Greek sigma: σ). Its length relies upon the quantity of waste material in it, but while reduced in size its diameter is handiest approximately one inch (2.Five centimeters).
The internal surface of the sigmoid colon is much like that of the rest of the huge intestine. The smooth mucous membrane lining secretes mucus and enzymes, and the lining’s floor cells can take in fluids. Most of these activities arise, however, better up in the intestinal tract. The deeper muscle layer of the sigmoid colon is composed of round muscle mass and a sheath of longitudinal muscle mass. Both assist move waste fabric within the colon, but the longitudinal muscle tissues are mainly accountable for evacuating wastes from this section. A circular muscle shape (sphincter) on the junction among the sigmoid colon and the rectum keeps cloth in the colon until it is ready to be handed. Strong longitudinal muscle contractions then expel waste material thru the sphincter and into the rectum. Fecal material can be stored in the sigmoid colon for seven hours or extra and is typically expelled when new waste material calls for access into this location.
Structure of the sigmoid colon
The sigmoid colon begins at the advanced aperture of the lesser pelvis, wherein it is non-stop with the iliac colon, and passes transversely across the front of the sacrum to the right facet of the pelvis.
It then curves on itself and turns in the direction of the left to attain the center line at the level of the third piece of the sacrum, where it bends downward and ends within the rectum.
Its feature is to expel stable and gaseous waste from the gastrointestinal tract. The curving direction it takes closer to the anus permits it to store gasoline in the advanced arched portion, permitting the colon to expel fuel without excreting feces simultaneously.
Sigmoid Colon function
The colon (large intestine) is the last part of the digestive system. It absorbs water, salt and some vitamins produced by the gut bacteria. The colon's main function is to store and eliminate stool. The colon's other functions are to: absorb water and some vitamins produced by the gut bacteria, lubricate and soften the stool as it passes through the colon, and provide a temporary storage space for stool.
The fundamental feature of the sigmoid colon is to transport fecal matter from the descending colon to the rectum and anus. This function is done with peristaltic waves that move the content material of the sigmoid colon. Feces shape inside the descending and sigmoid colon and gather in the rectum before defecation. In addition, some other feature of the sigmoid colon is to take in water, nutrients and different nutrients from the feces, earlier than they're moved to the rectum.

How is it diagnosed in the Large Intestine?
There are several conditions that can affect the large intestine (also known as the colon), such as inflammatory bowel disease (IBD), colorectal cancer, diverticulitis, and more. The diagnostic process can vary depending on the specific condition.
For example, if you're referring to inflammatory bowel disease (which includes Crohn's disease and ulcerative colitis), diagnosis often involves a combination of medical history evaluation, physical examination, blood tests, imaging studies (such as CT scans or MRIs), endoscopic procedures (colonoscopy or sigmoidoscopy), and biopsy of the affected tissue. Doctors use these methods to assess the extent and severity of inflammation in the large intestine.
On the other hand, for colorectal cancer, diagnosis may involve a combination of screenings, such as fecal occult blood tests, colonoscopies, and imaging scans. Biopsies of suspicious tissue are typically taken during a colonoscopy to confirm the presence of cancer cells.
