Give the names of three organs in the human body that secrete the enzyme amylase?
* The mouth produces salivary amylase: breaks down carbohydrate (starch) * The stomach produces pepsin and trypsin, which are two types of proteases: break down proteins * The pancreas and small intestine also make protease and lipase: digests fats into fatty acids and gycerol.
Which food goes from mouth to stomach?
It enters the duodenum, then jejunum, and then ileum of the small intestine. It is in the small intestine that nutrients are absorbed.
Where are enzymes that break down starch found?
Protines make up enzymes that break down starch, as well as other large moleculse, this process is called hydrolysis. Most enzymes end in "-ase" and work only in specific reactions. Polysaccharides such as glycogen are formed by linking many monosaccharides. The most common polysaccharides are starch, glycogen, and cellulose. All of these are polymers of glucose. They differ by the type of bond found between glucose molecules. Starch is the storage form of glucose found in plants; glycogen is the storage form in animals. Most glycogen in humans is stored in the liver and muscle. Human saliva also contains an enzyme called amylase. This enzyme helps to turn starch into a sugar called maltose. When your food gets into the small intestine, more amylase is made by the pancreas and this turns the remaining starch into maltose. Another enzyme (maltase) turns all this maltose into glucose. Glucose is then absorbed into the blood.
Why does bile make the pH level fall fast?
Bile is alkaline due to its high bicarbonate content, which helps neutralize stomach acid as it enters the small intestine. When bile is secreted, it rapidly increases the pH of the intestinal contents, counteracting the acidity from gastric juices. This process is crucial for creating an optimal environment for digestive enzymes to function properly and for nutrient absorption. Consequently, the introduction of bile can lead to a swift drop in acidity, resulting in a more neutral pH level in the intestine.
Which part of the digestive system is responsible for absorbing most of the nutrients?
The digestive system is made up of the digestive tract-a series of hollow organs joined in a long, twisting tube from the mouth to the anus-and other organs that help the body break down and absorb food (see figure). Organs that make up the digestive tract are the mouth, esophagus, stomach, small intestine, large intestine-also called the colon-rectum, and anus. Inside these hollow organs is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food. The digestive tract also contains a layer of smooth muscle that helps break down food and move it along the tract. Two "solid" digestive organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes called ducts. The gallbladder stores the liver's digestive juices until they are needed in the intestine. Parts of the nervous and circulatory systems also play major roles in the digestive system.

Which of th following is not one of the three segments of the intestine?
The three segments of the intestine are the duodenum, jejunum, and ileum, which make up the small intestine, along with the cecum, colon, and rectum, which are part of the large intestine. Therefore, any option that includes parts of the large intestine or does not belong to the intestinal structure, such as the stomach or esophagus, would not be one of the three segments of the intestine.
What are 3 parts of the small intestine?
The small intestine is the part of the gastrointestinal tract between the stomach and large intestine. The three parts that make up the small intestine are the duodenum, the jejunum, and ileum.
What is broken down by stomach churning and enzyme amylase?
The stomach breaks down mainly proteins into smaller polypeptides. However, amylase will not break anything down in the stomach because it is denatured by the acid. Salivary amylase will break down amylose, a type of starch, but only in the few seconds of mastication. Once the bolus reaches the stomach, the salivary amylase is no longer active. Carbohydrates will be broken down again in the small intestine, where pancreatic amylase will make a return after the chyme is neutralized into a basic solution.
How make a small intestine?
Need scale and purpose to answer.
Where are stem cells that make new cells to protect the intestines in adults?
in the bones
What is the role of the small intestine in the digestive system of proteins and fats?
In the small intestine, the food you eat continues being digested, and then the nutrients and proteins your body needs make their way out of the small intestine and into the rest of your body. Then the matter that is left over passes through the small intestine into the large intestine...causing you to go to the restroom.
Which organs make digestive fluids?
esophagus, stomach, small intestine, large intestine
Where is the bile stored and secreted from?
The bile is secreted in the liver and then stored in the gall bladder. When the pancreatic juice is secreted by the pancreas, it gets mixed with the bile juice and some intestinal juice which helps in the digestion in the intestine.
Chemical digestion occurs in the small intestine by enzymes from intestinal - brush border cells and the?
These enzymes are anchored into the cells that make up the brush border as integral membrane proteins. These enzymes are found near the transporters that enable absorption of the digested nutrients.
What is the function of the amylase?
The function of amylase is to break starch (a polysaccharide) into maltose in the mouth and duodenum. Maltose is then made into glucose (a polysaccharide) using maltase in the duodenum only
What enzyme is used to make maltose?
Name of this enzyme is Maltese. It is present in the brush border of the lining of small intestine.
