My digestive system is interesting. I've had chronic constipation since the age of three, and recently my number twos got drastically softer than usual, and my blood tests showed as if there was something wrong with my liver. I found out from a nurse (my mom) and a doctor we know, that it might be vitamin d deficiency. I got wonderfully skinny (waist circumference 81 cm) and started taking vitamin d regularly. it was really funny! I thought I was dying of liver cirrhosis and had to stop my favorite pastime (student parties) and it was just me forgetting to eat my vitamin d pills. Once I took my vitamins, my poop became harder and brown again. I actually found out what this whole poop shenanigan was, thanks to Hank and SciShow!

If your nervous your sympathetic nervous system will inhibit gastric secretion was the biggest take away for me.

Im wondering why vomiting can be caused by a miscommunication in the brain, like how car sickness is caused by your body saying "I'm sitting still" and your visual cortex saying "were on the move" I'm guessing it's an adaptation to poisons? Poisons can cause miscommunication therefor the body will try remove them from the body. I'm just speculating if anyone has a definitive answer please let me know
@maxk8486
6 жыл бұрын
Its not necessarily a miscommunication, its more just your body is getting ready for the fight/flight and so what happens is you don't want stuff in your stomach being digested and potentially using up energy that could be used in your fight/flight
@solaria9

You've pretty much hit it spot on. Your body hasn't caught up to modern times so it still assumes all miscommunication is from poison

Digestive system Ingestion Propulsion Mechanical breakdown Chemical digestion Absorption Defecation Mouth Pharynx Oesophagus Stomach Liver Gallbladder Pancreas Small intestine Large intestine Food is made of macromolecules theses macromolecules include carbs, lipids, proteins and nucleic acids. These macromolecules are polymers (sequences of smaller molecules put together). Cells can only take in a polymers individual component (monomers). Monomers include Fatty acids, sugars, amino acids and nucleotides. The whole point of the digestive system is to break down polymers into monomers that the body can use to make its own polymers and obtain energy from. Alimentary canal (gastrointestinal tract) runs from your mouth to your anus As food enters the mouth both mechanical and chemical digestion occurs. The teeth (incisors, canines, premolars and molars) crush and cut food and is an example of mechanical digestion. Chemical digestion takes place as amylase which breaks down carbs is released through saliva. After the bolus (chewed food) is swallowed it travels past the pharynx, down the oesophagus where through muscle movements (peristalsis) the bolus reaches the stomach. The stomach has four layers in its lining from outermost to innermost the mucosa, submucosa, muscularis externa and serosa. The muscularis includes an additional layer of smooth muscle for mechanical digestion and the inner mucosa is almost entirely made up of mucous cells which produce a protective mucous to keep the stomach safe from acids. The lining contains millions of gastric pits which lead to tubular gastric glands which contain various secretory cells which create potent chemicals. For example parietal cells in the tubular gastric glands release hydrochloric acid to kill bacteria and denature proteins for easier breakdown from enzymes. When hydrochloric acid is combined with the inactive enzyme pepsinogen made by chief cells the combination results in pepsin.Pepsin is a powerful enzyme that breaks down proteins. Enteroendocrine cells in the tubular gastric glands release regulatory hormones, like serotonin and histamine to trigger the release of more acid by other cells or to contract muscle tissue. When needed somatostatin is released to inhibit secretions. G cells secrete gastrin which stimulates the release of other gastric fluids and controls muscle activity.
