Transcript of Large Intestine
It's a pouch that is considered the beginning of the large intestine. It receives fecal material from the ileum and connects to the ascending colon of the large intestine. Colon has four main functions, which are:
maintaining the water balance
providing a location for flora-aided fermentation.
It is composed of three parts: ascending, descending and transverse. The appendix, connected to the caecum, is a lymphatic organ, and it is part of the immunitary system. Colon Colon The ascending colon is the part of a colon located between the caecum and the transverse colon.
It is smaller than caecum. The ascending colon runs thought the abdominal cavity, upwards toward the transverse colon for approximately twenty centimeters.
One of the main functions of the colon is to remove the water and other key nutrients from waste material and recycle it back into the body. The transverse colon is the part of the colon from the hepatic flexure to the turn of the colon by the spleen. The transverse colon hangs off the stomach, attached to it by a wide band of tissue, called the greater omentum. Cancers form more frequently further along the large intestine as the contents become more solid (water is removed) in order to form feces. The descending colon is the part of the colon from the splenic flexure to the beginning of the sigmoid colon. The function of the descending colon in the digestive system is to store food that will be emptied into the rectum. Rectum The rectum is the final straight portion of the large intestine. The human rectum is about 12 centimeters (4.7 in) long, and begins at the level of the third sacral vertebra. In humans, the rectum is followed by the anal canal, before the gastrointestinal tract terminates at the anal verge. The rectum intestinum acts as a temporary storage site for feces. When the rectum becomes full, the increase in intrarectal pressure forces the walls of the anal canal apart, allowing the fecal matter to enter the canal. Bacteria make up most of the flora in the colon.
Their main functions are: fermenting unused energy substrates, training the immune system, preventing growth of harmful, pathogenic bacteria, regulating the development of the gut, producing vitamins for the host and producing hormones to direct the host to store fats. A bowel movement is the last stop in the movement of food through your digestive tract. It is made of what is left after your digestive system, absorbs nutrients and fluids from what you eat and drink.
It's also called stool or feces. Stool passes out of the body through the rectum and anus.
