The digestive system is essentially a long tube, which starts from the mouth and ends at the anus.
The system's goal is to break down food for absorption into the body.
Related digestive organs, such as the liver, turn nutrients into substances that can be used for energy production and for the creation and repair of body tissues, cells, and blood constituents — metabolic processes that lead the digestive process a step further.
The human body needs the energy to function. That energy comes from food, but only after it has been processed into substances that can be assimilated by various parts of the body.
Some nutrients, such as minerals, can be absorbed directly along the way down the digestive tract, but substances such as proteins have to be broken down into smaller molecules.
Digestion starts in the mouth, where saliva containing amylase, a digestive enzyme, lubricates food when it is chewed.
In an acidic environment, proteins and fats are broken down in the stomach, and salt, water, and alcohol are taken up.
Acidity is neutralized outside the stomach (in the duodenum) until the food is processed with secretions from related digestive organs — the liver, gallbladder, and pancreas. Liver and gallbladder bile emulsifies fats, while pancreatic enzymes break down proteins, starch, and fats.
The liver is, in effect, the chemical factory of the body. Among many critical metabolic functions, it stores glucose, vitamins, and minerals produced by food processing but not immediately usable by the body and facilitates the breakdown of fats, which is vital for the conversion of food into energy.
As well as digestive enzymes, the pancreas produces insulin (a hormone), and glycogen (a starch), both of which regulate sugar levels. Diabetes is the result of diminished insulin action. In the small intestine, the breakdown of food is completed.
Nutrients are absorbed into the blood, carried to cells, and used in the release of energy.
Undigested food is expelled from the anus. Digestive ailments such as irritable bowel syndrome or ulcerative colitis are believed to result from, among other factors, an unsuitable diet or chemical imbalances in the metabolic process.
Indigestion, constipation, bloating or gastrointestinal ailments are only one of the few digestive system related issues.
The key factors that affect the proper functioning of the digestive system are nutrition, lifestyle, as well as the stress level to which we are exposed daily.
Proper digestion of the food is necessary in order to provide an immune system, healthy, balanced well-being, and to be energy-effective.
For this reason, we suggested providing more information on the digestive apparatus and exploring the list of plants that serve to treat ailments and disorders of the gastrointestinal tract but also to adjust the digestive system's optimum functioning.
The digestive system is responsible for the transformation of the products that we absorb for the whole body into energy and nutrients.
The system consists of numerous muscles, nerves, hormones, bacteria, and blood vessels that work together to ensure the proper nutrients to sustain the organism.
The digestive system does not operate as a single or separate entity, though.
It is closely linked to the nervous system, endocrine system, and the immunity system because the digestive process starts from the hypothalamus, the part of the most significant part of the brain ( Cerebrum ) that is responsible for stimulating the appetite.
In addition, the brain is what affects the way you digest the food, besides the health and welfare of the organism.
The time for food digestion varies depending on each of the individual's gender.
The digestive cycle spans 6 to 8 hours from the moment we feed, and before the food enters the colon.
As we have mentioned, the digestive system is made of many organs; each one has its role in the digestion process. Here is how, overall, the food digestion happens :
The new organ is observed in our digestive systems , known as
the mesentery, and was long thought to be assembled of fragmented, separate structures.
Yet recent work has shown it
is in fact one, continuous organ.
The mesentery is a double fold of peritoneal tissue that suspends the small intestine and large intestine from the posterior abdominal wall. .
The ‘root’ of the mesentery is the point where the mesentery attaches to the posterior abdominal wall, and is therefore a ‘bare area’.
One of the earliest descriptions of the mesentery was made by Leonardo da Vinci, and for centuries it was generally ignored as a type of insignificant attachment. Over the past century, doctors who studied the mesentery assumed it was a fragmented structure made of separate sections, which made it pretty unimportant.
The mesentery is formed by a double layered fold of peritoneum.
Although the mesentery is now thought to be a contiguous structure, subsections of the mesentery can be named according to the viscera it is associated with. Thus, names such as mesocolon, mesorectum, mesosigmoid all relate to different parts of the mesentery.
The ‘root’ of the mesentery is the point where the mesentery attaches to the posterior abdominal wall, and is therefore a ‘bare area’. Due to the range of abdominal organs the mesentery envelopes, the root is long, narrow and has an oblique orientation, from the left side of the L2 vertebra to the right sacroiliac junction roughly.
In the gastrointestinal tract, there are six flexures of note: duodenojejunal, ileocaecal, hepatic, splenic, and those between the descending and sigmoid colon and the sigmoid and rectum. These flexures are often used to mark the distinction between different portions of the mesentery:
The areas of the mesentery that are flattened against the posterior abdominal wall (the right and left mesocolon and the medial mesosigmoid) are attached to the abdominal wall via an additional layer of connective tissue known as Toldt’s fascia. The fascia contains several lymphatic channels.
