What else can I help you with?
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.
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
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.
How do enzymes produced in the pancreas come in contact with food since the food does not pass through the pancreas?
Enzymes produced in the pancreas are secreted into the small intestine through the pancreatic duct. When food enters the small intestine from the stomach, these enzymes mix with the food as it is digested. This allows the enzymes to break down carbohydrates, proteins, and fats, facilitating nutrient absorption. Thus, even though food doesn't pass through the pancreas, the enzymes reach it effectively in the small intestine.
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
What organ is NOT known to secrete a lipase?
The pancreas secretes many digestive enzymes (amylase, lipase, ribonuclease, deoxyribonuclease, gelatinase. proteases: carboxypeptidase, elastase, trypsin and chymotrypsin).Other digestive substances come from the saliva glands, stomach, small intestine, and liver.
What organ connects a frogs circulatory system and digestive system?
The digestive system organs of a frog are actually very similar to a human's digestive system. They have a stomach, 1 intestine, a liver, a gall bladder, and a rectum.
What is bile and amp where does it come from?
Bile is a digestive fluid produced by the liver that aids in the emulsification and absorption of fats in the small intestine. It is composed of bile salts, cholesterol, bilirubin, and other substances. Bile is stored in the gallbladder and released into the small intestine when needed, especially after consuming fatty foods.
What contains digestive enzymes that help clean up the cell?
The lysosomes contains digestive enzymes that help clean up the cell. It also helps in breaking down the complex compounds that come into the cell.
What is the sequence of structure through which an absorbable food passes through the mouth to the anus?
The absorbable food passes through the mouth, then through the esophagus (throat), into the stomach, small intestine where most nutrients are absorbed, and finally into the large intestine where water is absorbed before being expelled through the anus.
Which organ system contains the intestines?
intestines: Digestive system lungs: Respiratory system
