Digestive System

Helicobacter pylori protects its enzymes against stomach acid by secreting urease, an enzyme that breaks down urea into ammonia and carbon dioxide. The ammonia helps to neutralize the acidic environment around the bacteria, allowing them to survive and colonize the stomach lining. Additionally, H. pylori can also produce a protective barrier of mucin to shield itself from the gastric acid.

no.the large does,and not for long.it has to be excreted.

in wall of GIT the muscularis layer is composed of longitudinal and circuler fibers and the myentric nerve which is the part of enteric nervoius system is present between the longitudinal and circuler fibers

John Panozzo, co-founder of the band Styx, passed away in 1996 at the age of 47 due to a gastrointestinal hemorrhage. His death was a significant loss to the music community and his bandmates.

Digestive juices is produced in the stomach and small intestine. The mouth does not produce digestive juices, it is only saliva. The food will stay in the stomach for 2-5 hours and digestive juices are added to make it softer and then, the food travels to the small intestine where more digestive juices are added.

The average cost for an upper gastrointestinal GI series can range from $200 to $1,000, depending on the facility and location where the procedure is done. This cost may also vary based on whether contrast material is used and if any additional imaging is needed. It is best to check with your healthcare provider or insurance company for specific pricing information.

Amylase helps the break down of starch into sugars (disaccharides). Amylase itself is not broken down. It is an enzyme and it doesn't enter into the reaction in any way. The disaccharide that is formed is sucrose, maltose or lactose.

Protein digestion begins in the stomach or abomasum of ruminants. Pepsin, an enzyme released in the stomach, helps break down proteins into smaller peptides. Further digestion of proteins occurs in the small intestine with the help of enzymes like trypsin and chymotrypsin.

Bioavailability is used to describe the fraction of an administered dose of unchanged drug that reaches the systemic circulation, so we need chemically stable drug in order to increase the chance of drug absorbance and thus increased bioavailability.

Pepsin is a digestive enzyme that does not function well in high pH conditions. It works optimally in acidic environments, like the stomach, where the pH is low.

Inability to absorb digested nutrients could indicate a disorder in the small intestine, particularly in the cells lining the intestinal walls responsible for nutrient absorption. Difficulty in secreting mucus might signal a disorder in the mucosal lining of various organs such as the digestive tract or respiratory system.

Peristalsis is the term used to describe the contractions that move food along the entire gastrointestinal tract, from the esophagus to the intestines. These rhythmic contractions help propel food and waste material through the digestive system for processing and absorption of nutrients.

The human digestive tract is approximately 6-9 meters long.

The stomach has a low pH (around 1.5-3.5) due to the presence of hydrochloric acid. It also contains digestive enzymes like pepsin, which help break down proteins into smaller molecules for absorption.

External digestion is a process used by some organisms such as fungi and spiders to break down food outside of their bodies. In this process, enzymes are secreted onto the food substance to break it down into smaller molecules that can be absorbed by the organism. This allows the organism to extract nutrients from the food source without ingesting it.

The digestive tract develops from a central cavity called the blastocoel. During embryonic development, the blastocoel is surrounded by the endoderm, which eventually forms the lining of the digestive system. This process is known as gastrulation.

The digestive glands in a crayfish help to produce digestive enzymes that aid in breaking down food into nutrients that can be absorbed by the crayfish's body. These glands are essential for the digestion process and help ensure that the crayfish can obtain the necessary nutrients from its food.

The upper gastrointestinal tract is approximately 20 feet long and comprises the esophagus, stomach, and duodenum. It is responsible for digestion and the initial breakdown of food.

The advantage is that the animal is able to eat much larger prey and use the organic materials it receives from the animal to more efficiently carry out processes in the body. There is a gastrovascular cavity that digests the food and also transports nutrients to specific places in the body. The extracellular digestion allows food that was eaten previously to keep on being digested while more food is eaten. Intracellular does not let this happen; the food vacuole has to be empty before eating more.

The Gastrointestinal System, linking the Gall Bladder and the Liver to the Duodenum.

Digestion breaks down food into nutrients that can be absorbed by the body. These nutrients are then used in cellular respiration, a biochemical process that converts these nutrients into energy (ATP) that cells can use to carry out their functions. So, the nutrients obtained through digestion are essential for the cellular respiration process to occur and provide energy to the body.

The two main phases of the digestive process are the mechanical digestion phase, which involves physically breaking down food through chewing and the movement of the stomach and intestines; and the chemical digestion phase, where enzymes and stomach acids break down food into smaller molecules that can be absorbed by the body.

Molars and the bath teeth that crush and grind food!

There are four basic layers: starting at the innermost (closes to the food) there's the mucosa, then submucosa, then muscularis, then serosa. The muscularis layer is made up of two distinct, concentric muscular layers, the inner circular and the outer longitudinal (named for the general direction of their muscle fibers).
The four basic tissue layers of the alimentary canal are: Mucosa, Submucosa, Muscularis externa, and the Serosa.
From outer to inner: serosa, external muscle layer consisting of outer circular and inner longitudinal, submucosa and mucous membrane

fats are broken down in the liver and gaul bladder

this is only

partialy right if i am not mistaken they are actually broken down using bile from the liver that was stored in the gaul bladder but am not 100% shure i was looking for this question and saw this and just had to replace it.
