Nutrition
Adficiency
Aficiency disease occurs when you are lacking a nutrient from your diet. Scurvy is a disease caused by a lack of vitamin C such as bleeding gums
Adeficency
Adeficency in vitamin D may Aries if a person is not getting enough sunlight. This is likely to cause a disease called rickets in children. As well as sunlight vitamin D can be obtained from food such as eggs and fish
The digestive system
In the mouth teeth chop food into small pieces and mix in with saliva Amylase starts to digest starch. The salivary glands make saliva containing amylase. The ocsophagus connects the mouth to the stomach. Food moves along by perialus (muscular contraction). The stomach contains acid to destroy microbes protease starts to digest protein. The liver stores sugar and produces bile. Bile neutralises stomach acid and emlilsifies fat. The gall bladder stores bile. The pancreas makes digestive enzymes. The digestin of the food is completed by enzymes in the small intestine. Small food molecules are obsorbd into the blood. The large intestine absorbed water. The rectum stores undergested food called faces these egestled (past out) at the aneus
Digestive enzymes
Amylase
Amylase is an enzyme that calalyses the breakdown of starch into sugars. Amylase is the mouth, pangeus and the small intestine.
Protease
Protease calalyes the breakdown of protein into amino acids. It is produced in the stomach and the small intestine.

Types of microbes
Bacteria
Bacteria consist of just 1 single cell. There are many different types they are also tiny. Bacteria are everywhere food, soil. There are 100 billion inside your body weighing almost 1kg. Causes nasty abscess Lactobacillus cheese and yogurt
Fugi
Fugi comes in various some are multicellular producesorce they are found everywhere air, food and soil . Can cause Trichophy in yeast ringhory, athlete’s foot.
Virus
Viruses are the small types of microbes even smaller than bacteria it can not reproduce outside of cells. It can be found everywhere. It causes Flu, chicken pox COVID 19 everything
Uses of microbes
Brewing wine and beer
It uses yeast, sugar and water. It works by yeast uses anaerobic respiration known as fermentation
-
Cheese
It contains enzyme bacteria milk and sometimes fungi it works by adding enzymes called rennet after bacteria have produced lacking acid in milk rennet makes milk proteins makes milk proteins turn into solid and this is basis for cheese
The small intestine
Engestion
The remaining contests of the large intestine are stored as facets before being passed out of the body through the anus
Assimition
Small molecules of food the blood into cells of the body where they are used for the cell prossesses
