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.
When you swallow a peanut does the peanut first come in contact with the peritoneal cavity digestive mucosa small intestine or pancreatic juice?
digestive mucosa
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.
After the stomach which come next in the alimentary canal?
Small intestine
Where do the digestive enzymes come from in the small intestine?
s
Tiny fingers-shaped structures that give the small intestine more surface area to absorb food?
Your liver And pancreas are shaped to help it do its job If you are in fifth grade and your doing this you should have just gotten it out of your science textbook (: happy to help
Why does the small intestine comes first?
The small intestines come first because they absorb the nutrients of the food we eat.
Most of the enzymes and chemicals secreted by the upper end of the small intestine come from?
The villi, saliva, the liver and the pancreas or the large intestine.
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?

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.
