  • Digestive system

  • Organic compounds

  • Chemical elements: basic elements, minerals, trace elements

  • Vitamins

Digestive system
DIGESTIVE SYSTEM

  • Biologically food, water and air are the physical requirements of all the living organisms.

  • Food is processed in the digestive system.

http://en.wikipedia.org/wiki/Digestive_system


Teeth
Teeth

Aune Greggas

http://fi.wikipedia.org/wiki/Hammas

People have 32 teeth (radiograph)

  • The teeth cut up and grind the food fine.

  • They have a very strong white enamel(mica).

  • Sugars and acids can break it.

  • This kind damage is called dental caries.

http://fi.wikipedia.org/wiki/Hammas


Dental caries
Dental caries

  • Dental caries is also known as tooth decay or a cavity.

  • It is a disease where bacterial processes damage hard tooth structure producing dental caries (cavities and holes in the teeth).

  • Washing teeth decreases it.

http://en.wikipedia.org/wiki/Dental_caries


Gingivitis
Gingivitis

  • The gingivitis is a usual disease among those whose teeth hygiene is low.

  • However, the gums can be healed if they are treated in the right way.

http://en.wikipedia.org/wiki/Gingivitis


Cancer in the mouth
Cancer in the mouth

  • Inflammatory diseases in the mouth and in the gums are common with smokers and those who tug tobacco or betel nuts.

  • They can lead to cancer.

Mouth
Mouth

  • When the food is grinded the saliva glands of the mouth adds to the crunch enzymes needed to break up the food into that kind of chemical compounds which can be used by the body.

http://en.wikipedia.org/wiki/Mouth

Salvary glands

http://en.wikipedia.org/wiki/Salivary_gland


Esophagus
Esophagus

  • When the food is swallowed, there are muscles which take it all the way through the esophagus to stomach by peristaltic wave.

http://fi.wikipedia.org/wiki/Ruokatorvi

http://en.wikipedia.org/wiki/Peristalsis


Cancer in esophagus
Cancer in Esophagus

  • The use of alcohol, even in smaller amounts, increases the possibility to get cancer.

  • Most it increases cancers in the mouth, esophagus, stomach, liver, pancreas and intestines.

http://en.wikipedia.org/wiki/Esophageal_cancer

Cancer in the esophagus.


Stomach
Stomach

  • In the stomach the chemical process to break up the food compounds continues with the enzyme pepsin (pepsinogen).

  • On the walls of the stomach there are also millions of gastric glands which secrete gastric juice.

  • It is mainly hydrochloric acid.

http://www.biohit.com/upload/dia/img/gastropanel/stomach_med.gif


Stomach ulcer
Stomach ulcer

  • 70 - 90% of stomach ulcers are associated with Helicobacter pylori, a spiral-shaped bacterium that lives in the acidic environment of the stomach.

  • Aspirin might make it worse.

  • Peptic ulcer precedes often stomach cancer.

Liver
Liver

  • The liver collects nutrients from the blood and stores them in the liver.

  • Among those nutrients are carbon hydrates, minerals, trace elements and vitamins.

http://en.wikipedia.org/wiki/Liver


Glykogen store
Glykogen store

  • If the blood sugar is high, the glucose in it is changed to glycogen and stored in the liver.

  • If the blood sugar is low, glycogen is released from store areas and broken to glucose. This keeps blood sugar level even.

http://en.wikipedia.org/wiki/Glycogen


Detoxifyer
Detoxifyer

  • The liver is also a detoxifyer.

  • It breaks down or transforms substances like metabolic waste, ammonia, alcohol, nicotine, caffeine, drugs and chemicals, so that they can be excreted.

http://www.liverdoctor.com/index.php?page=liver-detoxification

The liver of a child is not able to detoxify alcohol.


Hepatitis
Hepatitis

  • The hepatitis is the inflammation of the liver.

  • Symptoms are jaundice, fatigue, fluid accumulation in the abdominal cavity, and brain dysfunction due to liver failure.

  • Severe cases have a high risk of death.

http://en.wikipedia.org/wiki/Alcoholic_hepatitis

Alcohol hepatitis is due to the use of excess alcohol. Hepatitis is common also among drug users.


Liver cirrhosis
Liver cirrhosis

  • The cirrhosis is characterized by replacement of liver tissue by fibrosis, scar tissue and regenerative nodules leading to loss of liver function.

  • Cirrhosis is most commonly caused by alcoholism, hepatitis or fatty liver disease.

Pancreas
Pancreas

  • The pancreas is a gland which extracts insulin.

  • Insulin is a hormone which helps to transfer glucose to cells in the liver, muscles and fat tissue.

  • The disease which results of the lack of insulin is called the diabetes.

http://en.wikipedia.org/wiki/Pancreas


Blood sugar insulin

Diabetes
Diabetes

  • There are two types of diabetes.

  • Type 1 diabetes is inherited and begins already in the childhood.

  • Type 2 diabetes is found in adults with abdominal fatness and metabolic syndrome background.

http://en.wikipedia.org/wiki/Diabetes_mellitus

Polydipsia = excess thirsty

Polyhagia = excess hunger

Polyuria = excess urination


Gallbladder

The gallbladder stores bile.

Bile is released when food containing fat enters the digestive track.

Bile emulsifies fats in partly digested food to help their use.

Gallstones
Gallstones

  • Bile sometimes crystallizes to gallstones.

  • Especially foods with lots of fats can invite intense abdominal pain, when the gallstones begin to move.

http://en.wikipedia.org/wiki/Gallstone


Intestines
Intestines

  • After the food has been processed in the stomach, it enters through duodenum to small intestine (7 - 8 meters).

  • From the cecum it continues through the colon to the rectum and then to the anus.

http://en.wikipedia.org/wiki/Salmonella

Salmonella bacteria causes typhoid fever, paratyphoid fever and diarrhea.


Rotavirus
Rotavirus

  • Round rotavirus is the most common cause of severe diarrhea among infants and young children.

Linen seeds have been commonly used to help in constipation.


Organic compounds
ORGANIC COMPOUNDS

  • All the main organic compounds in the living organisms are made of water, carbohydrates, proteins (amino acids) and lipids.

  • Most of our food is also made of them.

http://www.food-faq.net/food/food_pyramid.gif


Water h 2 o
Water H2O
