Physical Nature of the Gut

Beyond the guts influence on various bodily functions, the gut's physical structure is equally fascinating.

Its intricate design and vast network are essential for efficient digestion and nutrient absorption.

Let's delve into some remarkable facts about the physical nature of your gut:

A Journey Through the 30-Foot Digestive Maze

Length of the digestive tract

The entire digestive system, from mouth to anus, is about 30 feet long in adults. This includes the esophagus, stomach, small intestine, and large intestine.

Technically everything inside this long tube is considered to be “outside” the body.

More Room Than A Tennis Court Inside You

Surface area on gut

When fully stretched out, the surface area of the small intestine alone is roughly the size of a tennis court, about 250 square meters. This extensive area aids in nutrient absorption.

Fast-Track Renewal Inside Your Gut

Gut lining replacement

The lining of your gut is one of the fastest regenerating tissues in the body.

It replaces itself approximately every 3 to 5 days to maintain optimal function and repair any damage.

Your Gut's Weighty Population

Gut microbiome weight

The gut microbiome, the community of trillions of microorganisms, weighs around 2 to 5 pounds, comparable to the weight of your brain.

The Strong Acid Bath in Your Stomach

Stomach acidity unusual gut facts

The stomach produces hydrochloric acid with a pH as low as 1.5 to 3.5, which is strong enough to break down food and kill many harmful bacteria.

This acidity is crucial for effective digestion and protecting the body from pathogens.

Which is why drugs like proton pump inhibitors which are prescribed for acid reflux can have negative long term effects on your health.

Villi: The Tiny Nutrient Grabbers

Intestinal villi

The small intestine is lined with tiny finger-like projections called villi.

Each villus is covered with even smaller hair-like structures called microvilli, dramatically increasing the surface area for nutrient absorption.

Uncoiling The 20-Foot Small Intestine

Length of the small intestine

The small intestine is about 20 feet long and is coiled up inside the abdomen. It is divided into three parts: the duodenum, jejunum, and ileum.

The small intestine despite its name is much longer than the large intestine.

The Water-Saving Power of Your Colon

Colon function

The large intestine, or colon, is about 5 to 6 feet long. It is responsible for absorbing water and electrolytes from indigestible food matter and forming solid waste for excretion.

It is called the large intestine because it has a larger diameter than the small intestine.

The Muscle Behind the Movement

muscle layers in gut

The gut is composed of multiple layers of muscle that contract rhythmically in a process called peristalsis.

This coordinated movement propels food through the digestive tract and this is essential to prevent constipation.

The Gut's Own Brain

Gut nervous system

The gut contains around 100 million neurons, more than the spinal cord. This enteric nervous system controls digestive processes independently of the central nervous system.


Your gut is a complex system integral to your overall health. By understanding these fascinating facts, you can better appreciate the importance of maintaining a healthy gut.

Incorporate gut-friendly habits into your lifestyle, such as eating a balanced diet, consuming fermented foods, and staying hydrated, to support your digestive health and overall well-being.

It has been shown that high levels of processed foods, a diet that lacks diversity and even high levels of stress can have a negative impact on gut health.

If things are out of balance, doing an advanced stool test like the Vibrant Wellness Gut Zoomer can help to identify the problem and we can help you with a treatment plan to get your digestive health back on track.
