What will happen if no small intestine?
The large intestine has, as its major function, the removal of water from the digestive tract at the end of the digestive process. (The small intestine is the primary absorber of nutrients from out of the digested material.) Without a large intestine, you'd have a much more liquid bowel emission. And you'd need to drink more water, too. It's not the best deal in the world, but it is something that can be lived with and just requires "management" on the part of an individual who has, due to accident or disease, lost the large or a large portion of the large intestine. A link is provided to the Wikipedia article on the large intestine.
Why is it important to increase surface area in the small intestine?
Millions of tiny hair-like protrusions, called villi, line the inside of the small intestine. They vastly increase the surface area of the intestines, to maximise diffusion of nutrients into the bloodstream. In fact, there are even smaller micro-villi covering the villi, to increase the absorption capacity even further! A constant supply of blood ensures a steep concentration gradient is maintained. This is a crucial factor for allowing as great an uptake of nutrients as possible.
How is self-digestion of the stomach and small intestine prevented?
Self-digestion of the stomach and small intestine is prevented by the mucus lining that protects these organs from the acidic and enzymatic activity of the digestive juices. Additionally, the cells of the stomach and small intestine have tight junctions that prevent digestive enzymes from leaking out and causing harm. The presence of bicarbonate in the mucus also helps to neutralize any excess acid that may come into contact with the lining.
What is the job of the villi?
The job of the villi is to increase the surface area of the small intestine, which allows for more efficient absorption of nutrients from food during digestion. They are small, finger-like projections that line the inside of the small intestine and contain blood vessels and lymphatic vessels to transport absorbed nutrients.
Are joints a organ?
Joints are not considered organs. Joints are structures in the body where two or more bones come together and allow movement. They are important for mobility and support in the body.
Why does the small intestine comes first?
The small intestines come first because they absorb the nutrients of the food we eat.

How does the large intestine look different from small intestine?
The small intestine is longer than the large intestine, although it has a smaller width. The small intestine is between the the stomach and and the large intestine. The large intestine is the last part of the digestive system.The Large intestine absorbs water, nutrients and salts. The small intestine absorbs carbohydrates, protein, fats, minerals and vitamins.Small intestine has finger-like projections (called villi) while these are absent in large intestine.ANS2:Small intestine helps in digestion and absorption of food while large intestine helps in reabsorption of food and elimination of wastes. ANS3:The small intestine is only small in its diameter. In herbivores, the small intestine may be around ten times longer than the large intestine. The small intestine is where the villi-covered walls absorb nutrients from the digested food. Once the nutrients are removed, the waste enters the large intestine where the water is removed and the waste is consolidated. The origin of the following quote is linked: The small intestine in adults is a long and narrow tube about 7 meters (23 feet) long. The large intestine is so called because it is wide in diameter. However, it is shorter than the small intestine - only about 1.5 meters (5 feet) long.The small intestine is responsible for nutrient uptake, the large intestine is responsible for fluid uptake.Small intestine contains digest food and absorbs the nutrients from it. The large intestine contains food waste.The small intestine is longer than the large intestine, but it has a smaller width than the large intestine.The inside of the small intestine is covered in villi (making the interior look bumpy), but the inside of the large intestine is smooth.the small intestine finishes the brake down of the substance you consume and has villi which absorb simple nutrients such as amino acids, simple sugars and fatty acids. Then they are picked up by capillaries in the villi and transported throughout the body. On the other hand, the large intestine just transport the waste to the rectum and absorbs water.well, the small intestine breaks down food and passes the nutrient to the blood vessels and the large intestine eliminates all the wasteThe majority of digestion takes place in the small intestine, while the large intestine absorbs water from the remaining indigestible food and sends it out of the body.Also, the small intestine is longer, but has a thinner diameter than the large intestine, which is shorter but wider.
Where does bile's come from?
In most vertebrates, bile which is a greenish color is produced by the liver. Once produced by the liver, bile is stored in the gallbladder until the food being digested (at this point called chyme) enters the first part of the small intestine (called the duodenum), at which point the bile is passed into the small intestine as well.
What is the function of small intestines?
Answer The small intestine is responsible for absorbing most of the nutrients found within your food. By the time ingested food reaches the small intestine, it has been mechanically broken down into a liquid. As this liquid flows across the inner surface of the small intestine (which has many small folds to increase the surface area), nutrients within the food come into contact with the many small blood vessels which surround the small intestine. This blood then leaves the small intestine, carrying away nutrients, water electrolytes, vitamins, minerals, fats and medications to the entire body. It can take three to six hours for a meal to pass from one end of the small intestine to the other, and that is dependent on the makeup of the food passing through; meals containing a lot of fiber move more quickly. Absortion of nutients, vitamines , minerals and some water. Also propulsion of food along the intestinal lumen.

It can take three to six hours for a meal to pass from one end of the small intestine to the other, and that is dependent on the makeup of the food passing through; meals containing a lot of fiber move more quickly. while the large intestine:is the thick, lower end of the digestive system, containing the appendix, colon and rectum. Its principle function is to reabsorb water and maintains the fluid balance of the body. Certain vitamins are also taken in through the large intestinal wall. Further down the intestine, in the rectum, faeces are stored waste before it is eliminated. Another function is to process undigestible material (fibre), which makes up the bulk of the waste products.
Most of the enzymes and chemicals secreted by the upper end of the small intestine come from?
The enzymes and chemicals secreted by the upper end of the small intestine primarily come from the pancreas and liver. The pancreas releases digestive enzymes such as amylase, lipase, and proteases, while the liver produces bile which aids in the digestion and absorption of fats.

How does the villi help the small intestine to absorb sugars quickly?
Surface Area and DiffusionThe small intestine is all about maximizing surface area. The immense amount of folding enables it to be very long meaning more surface area. The villi further increases surface area. They are projections that provide even more membrane surface area that food, while passing through the small intestine, will come in contact with. This contact with the membrane of the small intestine is how absorption occurs. Nutrients that are used in the body will diffuse across the intestinal membrane into the blood stream because the concentration will be high inside the intestine and low in the blood plasma. This difference in concentration is what "drives" diffusion across the membrane.
