Chyme (output from the stomach) flows from duodenum, through to the rest of the small intestine, onto the large intestine, a 27 “ snake.
The chyme drops from the stomach and into the small intestine. Our small intestine is astonishing and is primarily where the minerals and nutrients from the food we eat are absorbed. The small intestine can vary in size according to the individual, but can be as long as 30 ft in some people. The small intestine is made up of three parts; the duodenum, the jejunum, and the ileum.
It passes the pancreatic duct, which delivers the enzymes. There are a number of enzymes generated by the pancreas however the 3 main pancreatic enzymes are proteases, lipase, and amylase which break up proteins, fats, and carbohydrates respectively.
Then it passes the bile duct, which delivers the bile. Bile is a thick nasty substance that emulsifies the fat that passes through the duodenum.
Once past the duodenum, this new mixture of chyme will pass through the small intestine. The small intestine grabs it and, using its’ peristalsis, slowly passes the chyme through its’ length, kind of like an elastic band being threaded through a wasteband.
As it passes through this section of intestine, which is the width of a baby finger, the bacteria are determining what gets absorbed into the body and what moves on to the large intestine.
The ileocecal valve opens between the small intestine and large intestine and showers down the 80-90 % digested and absorbed chyme. Then the large intestine grabs it with its peristalsis action and starts to process it through its length.
This is where your poo is made by absorbing the remaining water and “packaging” your waste into fecal matter until your body is able to defecate and eliminate waste through your body.
