The Small Intestine The Duodenum. The most proximal portion of the small intestine is the duodenum. Its name is derived from the Latin ‘duodenum digitorum’, meaning twelve fingers length. It runs from the pylorus to the duodenojejunal junction. The duodenum can be divided into four parts; superior, descending, inferior and ascending.

Colon Cancer Colon Cancer Overview. The human colon, or large intestine, is a muscular, tube-shaped organ measuring about 4 feet long. It extends from the end of your small bowel to your anus. Typically the first or right portion of the colon which is called the ascending colon moves up from the lower right portion of the abdomen. The next portion, or transverse colon, moves across from the right to the left side of the upper abdomen.

Why Do I Have A Painful Burning Sensation After A Bowel Movement? Undue pressure on the veins that make up internal hemorrhoidal structures can worsen existing damage. Internal hemorrhoids are not visible, unless they proplapse (protrude) from the anus, either constantly or during a bowel movement. If this is the case, then you have a grade III or IV internal hemorrhoid. If the protrusion is on the anal verge or the area surrounding the anus, then its likely an external hemorrhoid.

Large intestine The large intestine, or the large bowel, is the last part of the gastrointestinal tract and of the digestive system in vertebrates. Water is absorbed here and the remaining waste material is stored as feces before being removed by defecation. Most sources define the large intestine as the combination of the cecum, colon, rectum, and anal canal.

Large intestine The transverse colon is encased in peritoneum, and is therefore mobile (unlike the parts of the colon immediately before and after it). Cancers form more frequently further along the large intestine as the contents become more solid (water is removed) in order to form feces.

Toxic Megacolon The large intestine is the lowermost section of your digestive tract. It includes your appendix, colon, and rectum. The large intestine completes the digestive process by absorbing water and passing waste (stool) to the anus. Certain conditions can cause the large intestines to malfunction.

- Normal Bowel. 1  Large bowel is identified by the sacculations called haustra scattered all along the colon. 2  The colon has fat filled tags called appendices epiploicae on its surface. 3  These haustra and epiploicae separate the large from the small intestine.  Colon is filled with feces which has bubbly appearance.

Top 30 Doctor insights on: Where Is The Large Intestine Located In The Human Body Rectal prolapse is a condition in which the rectum (the last part of the large intestine before it exits the anus) loses its normal attachments inside the body, allowing it to telescope out through the anus, thereby turning it “inside out”.

- Pneumatosis intestinalis (PI) is defined as the presence of gas in the bowel wall [1–4]. This imaging finding is associated with numerous conditions, ranging from benign to life threatening [1–5]. The overall incidence of PI in the general population has been reported to be 0.03% based on an autopsy series [4].

Colon (Large Intestine): Facts, Function & Diseases The ascending colon is the right arm of the broken rectangle. The beginning of the ascending colon is called the cecum. The cecum is connected to the small intestine and the appendix. The transverse colon is the top arm that spans from the left side to the right side like a bridge. The left arm is called the descending colon.

Ascending colon The ascending colon (or right colon) is the beginning part of the colon. It is usually located on the right side of the body, extending from the cecum upward. Although the colon is a continuous structure, the piece that is considered the ascending colon ends where the colon bends, just below the liver and gallbladder.

- The intussusceptum is the invaginated segment of the alimentary tract, whereas the intussuscipiens is the enveloping segment. Invagination may occur in an antegrade (aborad) or retrograde (orad) direction, but is most commonly in the antegrade direction.

Intramural bowel gas There are different terminologies in the medical literature, such as pneumatosis intestinalis, pneumatosis coli, and pneumatosis cystoides intestinalis. Pneumatosis coli is used when only the colic wall is involved, and is generally an incidental finding in asymptomatic patients. Pneumatosis cystoides intestinalis is descriptive for multiple gaseous cysts along the bowel wall.

Bowel obstruction There are two sections of the bowel: the small bowel, also called the small intestine, which is where the nutrients in the food are digested and absorbed; and the colon and rectum form the large bowel, or large intestine, which absorbs water from the digested food, forming it into stools (faeces/poo) that are passed out of the back passage.

Colon Cancer Typically, the first or right portion of the colon which is called the ascending colon moves up from the lower right portion of the abdomen. The next portion, or transverse colon, moves across from the right to the left side of the upper abdomen. Next, the third region or descending colon moves down the left side of your abdomen. Then an S shaped or sigmoid colon portion of the large intestine connects the rest of the colon to the rectum, which ends at the anus.
