Large intestine, the back part of the intestine, typically consisting of four regions: the cecum, large intestine, rectum, and anus. The term

The large intestine is wider and shorter than the small intestine (about 1.5 meters, or 5 feet, in length compared to 6.7 to 7.6 meters, or 22 to 25 feet, in length for the small intestine) and has a smooth inner wall. In the proximal or upper half of the large intestine, enzymes from the small intestine complete the digestive process and bacteria produce B vitamins (B)

, thiamine, and riboflavin) as well as vitamin K. However, the primary function of the large intestine is the absorption of water and electrolytes from digestive waste (a process that usually takes 24 to 30 hours) and the storage of fecal material until it can be expelled. Nucleating movements of the large intestine gradually expose digestive residues to the absorptive walls. A progressive and more powerful type of movement known as the gastrocolic reflex, which occurs only two or three times daily, propels the material toward the anus.

Common ailments of the colon include inflammation, such as colitis; diverticulosis; and abnormal growths, such as benign or malignant tumors. The large intestine is the part of the digestive system responsible for extracting water from the indigestible remains of food. The large intestine is also called the colon and is about 5 feet long and 3 inches in diameter.

It consists of four regions, the cecum, colon, rectum, and anus. The large intestine is wider and shorter than the small intestine and has a smooth inner wall. Functions of the Large Intestine The large intestine performs four main functions, included below:

Disorders and Conditions of the Colon The most common diseases and disorders of the colon are included below:

Depending on the disease and its severity, the treatment of the colon diseases can vary greatly. According to recent research, the colon and its resident bacterial population play significant roles in determining our health and well-being. The colon is much more than a storage facility for waste.

The intestines are responsible for the majority of the body’s absorption of fluids and nutrients.

The gut plays an important role in maintaining the health of the body by supporting digestion, absorption and elimination and by regulating the immune system and electrolyte balance. It is home to a large population of beneficial bacteria, known as the gut microbiota, which play a role in supporting the immune system and helping to prevent the growth of harmful bacteria.

Overall, the gut plays an important role in maintaining the health of the body by supporting digestion, absorption and elimination and by regulating the immune system and electrolyte balance.

The main causes of intestinal problems are stress, low-fiber diet, lack of exercise and overconsumption of dairy products.

How Your Digestive System Works

Swollen stomach, cramps, gas, abdominal pain, bleeding, pain in the stomach and diarrhea are signs that you are suffering from intestinal problems.

Staying hydrated and drinking plenty of water are also great ways to control digestion. Drinking lukewarm water has also been shown to be beneficial for digestion. Try to eat lots of meals with a high water content as well. Fruits and vegetables including watermelons, tomatoes, lettuce and celery are included in this.

Reduced blood flow, eating a low-fiber diet, food poisoning, gas, bowel disease and lack of exercise can damage your gut.

Apple cider vinegar, apple, garlic, lemon, water, avocado, broccoli, spinach, juice, herbal tea and watermelons are some of the foods that help cleanse the intestines.

The organs of the digestive system can be divided into two main groups: those that form the digestive tract and the accessory digestive organs.

Functions Of The Intestine

The alimentary canal, also called the gastrointestinal tract, is a continuous, hollow muscular tube that winds through the ventral body cavity and is open at both ends. Its organs include the following:

The role that teeth play in food processing needs little introduction; we chew, or chew, by opening and closing our jaws and moving them from side to side while continuously using our tongue to move food between our teeth.

Specifically, the digestive system takes in food (consumes it), physically and chemically breaks it down into nutrient molecules (digests it), and absorbs the nutrients into the bloodstream, then rids the body of indigestible residues (defecates).

The activities that take place in the mouth, pharynx and esophagus are food intake, food breakdown and food propulsion.

The sight, smell and taste of food stimulate the reflexes of the parasympathetic nervous system, which increases the secretion of gastric juice from the gastric glands

What is ultimately delivered to the colon contains few nutrients, but that residue still has 12 to 24 hours left to spend there.

Age-related changes in the gastrointestinal system include decreased saliva, decreased esophageal and gastric motility, decreased gastric emptying time, decreased production of intrinsic factor, and decreased intestinal absorption, motility, and blood flow. In addition, the tooth enamel becomes harder and more brittle, making the teeth more susceptible to fractures.

Health promotion education for the elderly includes preventive dental care and effective oral hygiene, appropriate diet and adequate fluid intake, regular bowel maintenance and the importance of colorectal cancer screening.
