Digestive System

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.

Solid waste passes through the large intestine where the nutrients are digested and taken into the body by osmosisi. It continues on thru the digestive tract via waves of peristalsis, where digestion is assisted by the addition of digestive enzymes all thru the process . It then reaches the rectal vault , which is where it's stored (as faeces). It is then released out of the body via the anus.

Cells use digested foods as a source of energy to power various cellular processes, such as growth, repair, and maintenance. Nutrients from digested foods are also used to build and repair cellular structures, enzymes, and hormones. Additionally, cells can store excess nutrients for later use.

What Is An Elemental Diet? An elemental diet is - in a perfect world - a liquid diet consisting of completely pre-digested nutrients that include a combination of: protein, carbohydrates, vitamins and minerals. It is highly beneficial to also add an ample amount of Essential Fatty Acids such as, flax oil or coconut oil. An elemental diet (also known as an enteral diet) is often prescribed for people who suffer from autoimmune disorders such as Crohn's Disease, Diverticulitis, AIDS and severe cases of Cancer. Elemental diets are also used for pre and post-surgery patients who are not able to eat solid foods or who are malnourished. Recent clinical trials involving children with active Crohn's disease in England and Italy have demonstrated that "elemental diet therapy is as effective as steroids in inducing remission in people who suffer from gastrointestinal disorders whilst avoiding steroid side effects". As a result of these clinical trials, it is now beginning to be understood that an elemental diet can be used as an alternative to using steroids like prednisone, which can have undesirable side effects. Following an elemental diet is a difficult undertaking requiring a lot of self-discipline. If you're going to undertake something as difficult and restrictive as an elemental diet, then you might as well fully commit to it and use the period to facilitate a complete overhaul and root-level healing of your body and immune system. Many of the elemental diet formulas are primarily used in hospitals. Unfortunately, they are poorly formulated. Often times they taste bad, are loaded with artificial flavors and sweeteners, large amounts of sugar (in relation to maltodextrin) and high levels of low quality oils - which can actually result in painful intestinal spasming. To date, the highest quality and most tolerable, liquid diet drink is a powdered formula made by Imix Naturals called Absorb Plus. It has been specifically designed for people who need a completely pre-digested diet. Although it can also be used for either losing weight while maintaining muscle mass or gaining weight by building solid muscle mass, not fat. Absorb Plus can also be used in conjunction with "The IBD Remission Diet" - a very specific natural diet and supplementation plan devised to induce disease remission. The protocol is designed to completely heal the GI tract, starving off the bad bacteria in your intestine and replacing them with good bacteria, and restoring health and balance from the cellular level on up throughout the immune system. Although this elemental treatment is specifically formulated to address inflammatory bowel conditions like Crohn's, Ulcerative Colitis and Diverticulitis, people can likely find other health conditions will also be resolved as the program facilitates extensive whole-body healing. Typically, an elemental diet alone will not benefit people with Ulcerative Colitis or IBS, however as the elemental is only ONE component of The IBD Remission Diet, thousands with colitis or severe IBS have also used it as a tool to induce remission. This is most likely the result of the pathogens being cleared from the gastrointestinal tract and replaced with good bacteria, the supplements which heal the mucosal lining and intestinal wall, the whole-body detox provided by the elemental diet and the myriad of bodily functions assisted by the targeted amino acid blend and other herbal supplements prescribed.

Chemical digestion reduces large complex molecules to simpler compounds through the action of enzymes. Enzymes break down carbohydrates, proteins, and fats into smaller molecules that can be absorbed by the body for energy and nutrients. This process occurs in the stomach and the small intestine.

The mouth opens into the pharynx, not the uvula, soft palate, or larynx. The pharynx serves as a passageway for both air and food.

Bile enters the gastrointestinal tract at the duodenum, the first part of the small intestine. It is released from the gallbladder and helps in the digestion of fats by emulsifying them.

Macromolecules of digestion include carbohydrates, proteins, and fats. These complex molecules are broken down into smaller units during the process of digestion in order to be absorbed by the body for energy and nutrient storage.

Comparing the human system to a plumbing system implies that both involve the movement of materials through interconnected channels to various parts of a structure. In the case of the human body, it refers to how blood, nutrients, and waste travel through the circulatory, digestive, and excretory systems to sustain life and maintain health. Just like how plumbing systems keep a building functioning properly, the intricate networks within the human body work together to ensure its proper functioning.
