Anatomy Of The Colon And Rectum
The human digestive system is made up of a small intestinal tract and a large intestine. The rectum and the colon are both parts of the large intestine. We will discuss how the colon works as well as the rectum. It is necessary to take consultation from the best Fistula Doctor in Kolkata.
Anatomy and Physiology
The colon is the longest section in the large intestine. It is a long, tube-like organ that drains water from the food that has been digested. It is also divided in:
The ascending colon is the place where the large intestine, into which the small intestine is empty. it starts on the lower left side of the abdomen. It goes up towards the transverse colon. It’s 20cm long.
The transverse colon extends across the abdomen’s top from left to right which leads to the lower colon, which eliminates waste from onto the right side. It is the biggest and most mobile part of the colon, measuring around 45 cm in length.
Descending colon follows the traverse colon and is located on the left in the abdominal area. It’s about 30 cm long.
In the end, the sigmoid colon is the end of the colon, which takes the waste away for a few more inches down towards the rectum. It’s 40cm long. A cross-sectional view of the sigmoid colon and rectum will show the place where waste exits the body by the system of the anus.
The transverse colon and ascending colon are referred to as colon proximal, whereas the colon descends and the sigmoid colon is known as the distal colon.
Its length is approximately 15cm. It connects the sigmoid colon to the canal of the anal. The colon is a storage facility for waste until it is released from the anus.
The colon is divided into layers and the rectum
It is composed of layers of tissue that form the colon and the rectum. They include:
The lining that surrounds both the rectum and colon is called the mucosa. It is composed of:
A thin layer of epithelial cells referred to as epithelium
connective tissue layer
Muscle layer is known as the mucosa of the muscular
The submucosa is the layer of connective tissue that surrounds the mucosa. It is home to mucous glands, lymph vessels, blood vessels, and nerves.
The muscularis propria is located in the submucosa. It is an extensive skin of muscle.
The outermost portion of the colon is known as the serosa, which is absent in the majority of the rectum.
Functions of the colon as well as the functions of the rectum and colon

Get rid of waste in the body
After digestion, food particles move through the colon via the small intestine. The colon’s tissues contract and relax, allowing food particles to move through the rectum and colon. This is known as peristalsis.
Within the colon, the bacteria break down food particles into smaller pieces. The mucosa’s outer layer mucosa sucks up water and other nutrients.
The remaining liquid waste is from the semi-solid stool. Mucosa also produces mucus, which helps stool easily move through the rectum and colon. When stool travels through the colon it absorbs more water and then becomes more solid.
After the colon is empty The stool is then moved into the rectum. The rectum houses the space to hold the stool. When the rectum is fully filled it will throw the stool away from the body through the anus.
How can you keep the health of the colon and the rectum?
Most colon and rectal issues result from poor stool movement. Sometimes, they’re too rigid or too loose. A bowel movement that is too hard can cause cuts or tears in the region of the anal and loose bowel movements can be a nuisance around the anal area and cause itching around the opening of the anal. So, if the volume and frequency of the bowel movements is adequate, then constipation and rectum issues will go away. A balanced food plan, simple elimination, and proper cleansing can help prevent issues with the colon and rectum.
