Does lipase come from animals?
Lipase is produced in the pancreas as well as is present in the intestinal juice of human.
What substances are released into the small intestine to help in digestion?
Bile is released from the liver to help emulsify fats, and pancreatic juice is released from the pancreas. This is a mixture of bicarbonate, to neutralise stomach acid and enzymes to catalyse the breakdown of nutrients in food. These enzymes include proteases, both active and inactive, amylase and lipase.
Why doesn't the small intestine contain the acid chyme?
The duodenum is the main site for digestion in the small intestine. Here, more enzymes are added to the chyme, some of which come from the intestinal wall and others from the pancreas. The pancreas is one of the major glands of the body, and has two functions: releasing digestive enzymes into the gut, and releasing hormones into the blood. Pancreatic juice also contains sodium bicarbonate, which neutralizes the acid chyme arriving in the duodenum, and provides an alkaline environment for optimum functioning of pancreatic and intestinal enzymes. These enzymes include proteases to continue protein digestion, amylase for carbohydrate digestion, and lipase for fat digestion. Enzymes in the intestinal juice generally start off the later stages of digestion.
When you swallow a peanut does the peanut first come in contact with the peritoneal cavity digestive mucosa small intestine or pancreatic juice?

Why does the small intestine comes first?
The small intestines come first because they absorb the nutrients of the food we eat.
Tiny fingers-shaped structures that give the small intestine more surface area to absorb food?
These finger-shaped structures are called villi. Villi increase the surface area of the small intestine, allowing for more efficient absorption of nutrients from food. This increased surface area helps in maximizing nutrient absorption into the bloodstream.
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.
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.
Functions of the small and large intestine?
The small intestines are 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. 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.
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.
