Large intestine main functions:
1. ~> Absorption of water and vitamins
2. ~> Formation of faeces

[ •  After the absorption of nutrients is completed in the ileum, -undigested food, dead cells, epithelial cells, fibre and water- enter the large intestine and move slowly through peristaltic action. ]

1. Substances absorbed are
~> Water and mineral salts
~> Metabolic byproducts of some bacteria such as vitamin B, K and folic acid.

2. Formation of faeces
~> After water is absorbed, the remaining waste is a semisolid called faeces. Faeces contains dead cells from the inner layer of the intestine, waste products such as bile pigments, bacteria and toxic substances.
~> Walls of large intestine secrete mucus to smoothen faeces movement until the anus. Faeces’s movement takes about 12-24 hours before entering rectum.
~> The faeces will accumulate in the rectum until the pressure in the rectum increases and triggers the need to expel faeces from the body.
~> The rectum muscles will contract to expel faeces from the anus.

And this process is called Defaecation.

DEFEACATION

All of undigested food, dead cells, epithelial cells, fibre and water will enter the large intestine and move slowly through peristaltic action.

FUNCTION OF LARGE INTESTINE
• absorp water and vitamin
• formation of feaces

So what really happen in the large intestine?

ABSORPTION OF WATER AND VITAMINS
A few substances are absorbed in the large intestine, which is :

Water & mineral salts

metabolic byproduct of bacteria(vitamin B,K and folic acid)

FORMATION OF FAECES

As we know that water is absorbed in large intestine, then there is waste remain which is called faeces. It contain dead cell from large intestine & waste product(bile pigment,bacteria,toxic substances)

The faeces will move into the rectum by the help of mucus secreted by walls of large intestine. It will take about 12 to 24 hours.

Faeces will accumulate in rectum until pressure increases and triggers the need to expel faeces.

DEFAECATION is the discharge of faeces from body. It is final act of digestion, which organism eliminate their undigested waste material from digestive tract via anus.

Defecation (or defaecation) is the final act of digestion, by which organisms eliminate a solid, semisolid, or liquid waste material known as feces from the digestive tract via the anus.

ABSORPTION OF WATER AND VITAMINS

Substances absorbed are:

•water and mineral salts

•metabolic byproducts of some bacteria such

as vitamin B, vitamin K and folic acid.

FORMATION OF FAECES

•After the water is absorbed, the remaining waste is a semisolid called faces. Faeces

contains dead cells from the inner layer of the intestine, waste products such as bile

pigments, bacteria and toxic substances.

•The walls of the large intestine secrete mucus to smoothen the movement of faces until the

anus. The movement of faces takes about 12 to 24 hours before entering the rectum.

•The faces will accumulate in the rectum until the pressure in the rectum increases and

triggers the need to expel faces from the body.

•The rectum muscles will contract to expel faces from the anus. This process is called

defaecation.

LARGE INTESTINE

The large intestine absorbs water from the remaining indigestible food matter and compacts feces prior to defecation.

The large intestine starts in the right iliac region of the pelvis, just at or below the right waist, where it is joined to the bottom end of the small intestine. It is about 4.9 feet (1.5 m) long, which is about one-fifth of the whole length of the intestinal canal.

The function of the large intestine (or large bowel) is to absorb water from the remaining indigestible food matter, and then to pass the useless waste material from the body. The large intestine consists of the cecum and colon.

It starts in the right iliac region of the pelvis, just at or below the right waist, where it is joined to the bottom end of the small intestine (cecum). From here it continues up the abdomen (ascending colon), then across the width of the abdominal cavity (transverse colon), and then it turns down (descending colon), continuing to its endpoint at the anus (sigmoid colon to rectum to anus). The large intestine is about 4.9 feet (1.5 m) long—about one-fifth of the whole length of the intestinal canal

The large intestine is much broader than the small intestine and takes a much straighter path through your belly, or abdomen. The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over.

The 4 major functions of the large intestine are recovery of water and electrolytes, formation and storage of faeces and fermentation of some of the indigestible food matter by bacteria. The ileocaecal valve controls the entry of material from the last part of the small intestine called the ileum.

DEAFICATION

Defecation (or defaecation) is the final act of digestion, by which organisms eliminate a solid, semisolid, or liquid waste material known as feces from the digestive tract via the anus. The act is known by a variety of terms ranging from the common, like pooping, to the technical, i.e. bowel movement

FECES

Feces are mostly made of water (about 75%). The rest is made of dead bacteria that helped us digest our food, living bacteria, protein, undigested food residue (known as fiber), waste material from food, cellular linings, fats, salts, and substances released from the intestines (such as mucus) and the liver

What are the functions of the large
intestine ?

- After the absorption of nutrients is
completed in the ileum, undigested food,
dead cells, epithelial cells, fibre and water
enter the large intestine and move slowly
through peristaltic action. Fibre consists
of cellulose walls of plant cells.

The large intestine carries out two main functions :
- absorption of water and vitamins
-formation of faeces

ABSORPTION OF WATER AND VITAMINS
Substances absorbed are :
- water and mineral salts
- metabolic byproducts of some bacteria such

- The walls of the large intestine secrete mucus to smoothen the movement of faces until the

- The large intestine has a huge population of bacteria. There are more than 1000 different species of bacteria and a healthy balance between beneficial and less beneficial that is very important for health and a stable environment in the alimentary canal.

- The large intestine carries out two main functions which is absorption of water and vitamins and formation of faeces.

- The substances that is absorped are water & mineral salts and metabolic byproducts of some bacteria such as vitamin B, vitamin K and folic acid.

process in digestion , defecation is defined as the final act of digestion .

defecation also called bowel movement , the act of eliminating solid or semisolid waste materials (feces) from the digestive tract . In human beings , wastes are usually removed once or twice daily , but the frequency can vary from several times daily to three times weekly and remain within normal limits .

the process of eliminating stool from the body requires the work of the defecation reflex . this link explain more about defecation reflex .

DEFAECATION

functions of the large intestine

undigested food, dead cells, epithelial cells, fibre and water enter the large intestine then move slowly through peristalcis action, it happens after the absorption of nutrients in the ileum is completed

a. absorption of water and vitamins

the substances those are absorbed are water , mineral salts and metabolic byproducts of some bacteria such as vitamin B, vitamin K and folic acid

what is faeces ?

faeces is the solid or semi-solid remains of food that was not digested in the small intestine, and has been broken down by bacteria in the large intestine

b. formation of faeces

•faeces is the remaining waste that is a semisolid after the water is absorbed, it contains dead cells from the inner layer of the intestine, waster products such as bile pigments, bacteria and toxic substances

•the walls of the large intestine secrete mucus to smoothen the movement of faeces until the anus. its movement takes about 12 to 24 hours before entering the rectum

•the faeces will accumulate in the rectum until the pressure in the rectum increases and triggers the need to expel faeces from our body

•the rectum muscles will contract to expel faeces from the anus that is called defaecation
