The Muscular digestive Tube

The wall of the GI tube from the mouth to the anus (with a few exceptions) is made up of four basic layers.
This is the innermost layer of the digestive tube and lines the lumen.

It consist of three distinct layers:

This layer is in direct contact with the contents of the lumen and modulates secretion and absorption.
The ability to carry out the different functions of absorption, secretion and production of hormones is due to the presence within the epithelium of several different specialised cell types in different regions of the digestive tube.

Lamina Propria
This layer consists of connective tissue, blood capillaries, lymph nodules important for providing the basis of the immune system of the digestive tract and glands.
Muscularis mucosa
made up of thin smooth muscle layer that provides the mucosa the ability to dynamically move and create folds.
This layer is made up of loose to dense connective tissue, blood and lymph vessels and incorporates glands and lies immediately beneath the mucosa.
This layer also contains components of the Enteric Nervous System which provides nervous control to the mucosa.
3.Muscularis externa
this is a highly developed smooth muscle layer and involved in modulating gut motility.
This layer is found lining the entire GI tract except the upper Oesophagus and the Anal sphincter.
It is made up of two thick layers of smooth muscle-the inner circular muscle layer and outer longitudinal muscle layer.
This combination of circular and longitudinal smooth muscle provides the digestive tube with the ability to be motile. Coordinated Contraction and relaxation of the smooth muscles gives the tube an ability to perform tasks involving movements that squeeze, mix, grind and propel content in the lumen.

Between these two layers of smooth muscle is embedded a network of nerves that makes up the Enteric Nervous System.
This nervous system is critical for the functioning of the digestive tube.
This is the outermost connective tissue layer covering the digestive tube and consists of a thin layer of loose connective tissue covered by a type of epithelium called the mesothelium.


How to heal and prevent Bowel disorders

Diet is not about what you should NOT eat, it’s about what you should include in the diet that matters.
As long as your diet includes the correct balance of plant foods containing soluble fibre, insoluble fibre and resistant starch your colon will produce the perfectly formed stool. The important next step is to evacuate this stool without straining so that the body does not suffer from the pressures created each time the bowel is emptied.

In order to heal and prevent bowel disorders you need to make lifestyle changes that last the rest of your life time.

1. Include more fluids and plant food containing soluble fibre, insoluble fibre and resistant starch in the diet so that the perfectly formed stool will be made in the colon and beneficial bacteria will flourish and eliminate disease causing bacteria and fungi.

2. Evacuate the perfectly formed stool by adopting the squat posture to eliminate the need to strain during bowel movements.

It is not possible or safe to squat on the modern raised toilet seat installed in all western homes and it is impossible to squat for any length of time if you have not done this from childhood onwards. This makes the use of any raised platforms impossible to adapt to.

The SquattLooStool is designed to allow you to adopt the squat posture while seated comfortably on your raised toilet seat.
The single best and easiest lifestyle change you will ever make, leading to a healthier body.
