Your tooth grind up the cereal into smaller particles, making it simpler to swallow and digest. Your saliva accommodates an enzyme, a form of chemical, referred to as amylase that begins breaking down the cereal on a molecular degree.
I am a health care provider who usually treats youngsters and adults with digestive issues. A few of my sufferers have issues absorbing vitamins from their meals and others poop too usually or not usually sufficient. Once they describe their signs, I take into account the method of how our our bodies make poop and which steps can go incorrect.
Your abdomen is filled with enzymes and acid
Every little thing you eat accommodates three sorts of molecules that present your physique with the power it is advisable to reside: carbohydrates, fat and proteins.
Amylase, an enzyme in saliva, begins breaking down the starches, a form of carbohydrate, whereas the cereal continues to be in your mouth.
After you swallow, the milky cereal travels down your esophagus, a tube that carries swallowed meals out of your mouth to your abdomen. That is the place digestion actually will get going.
Your abdomen accommodates hydrochloric acid, which breaks the meals down into a lot smaller items. Over a number of hours, that acid and extra enzymes proceed to pulverize the carbohydrates and protein out of your bowl of cereal.

Your lengthy and winding small gut
Two or three hours later, your breakfast will go away your abdomen and enter the small gut, which is a protracted and coiled tube that’s contained in your stomach behind your stomach button. By that time, the digestive course of may have turned these huge chunks of cereal into tiny particles which are sufficiently small to your physique to soak up.

These thousands and thousands of villi create an enormous quantity of floor space, which is right for absorbing the vitamins in what you’ve got eaten as soon as it has been digested. The small gut additionally accommodates many sorts of micro organism, which help in breaking down the meals particles.
The small gut additionally produces extra enzymes to assist break down the carbohydrates in breads and pasta into easy sugars which are simply absorbed. As meals enters into the small gut, different organs additionally contribute their digestive juices to the combination.

Bile helps break down fat contained in meals. Pancreatic enzymes assist break down the carbohydrates, fat, proteins and the opposite vitamins within the meals you eat.

Your sluggish and quick colon
The journey via your small gut takes between two and 6 hours to finish. By this level, your bowl of cereal is unrecognizable. It has was chyme, a greenish liquid. Chyme will get its coloration from the bile made within the liver.
Because the chyme reaches the top of the small gut, it enters into your massive gut, often known as the colon. The big gut will get its identify on account of being wider than the small gut, regardless that it’s a lot shorter.
The colon is about 5 toes (1.5 meters) lengthy. Not like the villi-lined small gut, it would not soak up any vitamins. As a substitute it does one other vital job: It absorbs water from the slimy inexperienced chyme your digestive system comprised of your breakfast.
The small gut additionally absorbs water into the bloodstream, the place it’s delivered to your kidneys to make urine.
So the intestines additionally play a small half in making your pee, in addition to your poop.
This course of is way slower than these earlier steps. It might take an entire day, and as much as three days, to finish. By the point the chyme reaches the top of the colon, it has solidified and possibly turned from inexperienced to brown.
The brown coloration of poop comes from the bile that’s added by the liver to your bowl of cereal because it makes its method via the small gut. The bile is modified by micro organism from inexperienced to brown. With out bile your poop could be a pale silver or clay coloration.

A lot of micro organism
What’s in your poop?

Your intestines comprise trillions of those micro organism, which aid you digest what you eat. Not like another sorts of micro organism, they don’t make you sick. Those that come out as a part of your poop give it that smelly scent.
Every a part of your digestive system, out of your mouth to your colon, performs an vital position in extracting from what you eat the power and water that your physique wants. All of them work collectively that can assist you soak up most of that power and water, whereas eliminating what you do not want.
