Digestive System

i dont know why

the digestive cells are the small particles in our body. know we have 200,000 cells in our body that give us energy keep us alive.

digestion involves breakdown of complex food taken orally.the body cannot utilise this complex form of food.the particles should be small enough to allow the cells to utilise them and hence produce ATP required by the body.if no digestion takes place the body will never be able to get the energy required for various metabolic processes.

The diet of humans is made up of foods comprising nutrients and energy sources. The digestive process commences in your mouth, where food you have eaten is chopped by your teeth and therein your salivary glands secrete saliva which lubricates the food and contains enzymes that begin to break down carbohydrates during a period of about one minute. Your mouth also contains sensory nerves in the taste buds on your tongue. Your tongue manipulates food in the mouth and forms it into small balls called boli for easy swallowing and from your mouth the food then passes into the pharynx or throat, which then pushes it into your oesophagus or gullet

Foods high in protein take longest to digest. Also, high fibre foods take a while.

Glycogen can be digested by humans. Chitin and Cellulose, also knows as fiber, can not be digested by humans.

cellulose and insoluble fibers

The peristaltic movements are muscle contractions and its function on the esophagus is to push food down into the stomach and prevent it from going back into the esophagus.

Yes, the human digestive system works through muscular contractions which force the food and liquid along. This is why we have no problems in space (apart from getting the food to stay on the plate). You can demonstrate this by hanging upside down and eating a sandwich just fine.

Interestingly, the digestive system of many birds does depend on gravity; this was discovered during a Space Shuttle mission to see if birds could handle space.

yes because you mom is fat and she sits on the couch all day eating cheese puffs

Yes. Since neurotransmitters (including epinephrine - or adrenaline) are more heavily represented in the gut, than in any other organ outside of the brain, fear is a powerful stimulus in the digestive system, not only causing indigestion, but also diverting blood flow away from the intestines to the muscles - in preparation for the body's "fight or flight" responses.

bile is the emulsification agent that helps to digest fats.

Koalas have a really long and complicated digestive system because they only eat Leaves( Eucalyptus Leaves mainly), and these leaves contain toxins which allows their digestive system to take a longer amount of time to break down the food and digest.

no because bile is stored in the bile duct

HCI or hydrochloric acid helps to lower down the Ph value of stomach and thus activates Pepsin, which is an enzyme present in most juices, and helps to break proteins into smaller peptides.

In the large intestine.

we'd all be constipated.

Well, it's a fruit, and an excellent example of one at that.

you will choke and die

A Quote I thought may be of interest:

Crohn's disease is a chronic inflammatory disease of the digestive tract. The disease causes ulcerations of the small and large intestine. The disease can affect the digestive system anywhere from the mouth to the anus, but distinctively affects the terminal ileum as well as demarcated areas of large bowel. Crohn's Disease Symptoms • Chronic diarrhea & disrupted digestion: It becomes difficult for the patients in the acute phase of the disease to eat and/or digest food.

• Painful and debilitating inflammation

• Fistulas of the colon

• Hemorrhoids

• Lipid absorption problems

• Anemia: Persistent rectal bleeding may lead to anemia.

• Bruising of the shins.

• Fever, pain and psychological damage in many cases

• Crohn's disease in children may cause delayed development and stunted growth.

Constipation may be caused by varied reasons like eating less fiber, or drinking lesser fluids, side-effect of certain medicines, or related to any underlying medical condition. There are many cases in which, the cause is not clear. Laxatives are a group of medicines that can treat constipation.
