The digestive system
Mouth The digestion begins in the mouth
...
Chemical digestion happens in the mouth when the
chewed food is broken down from carbohydrates into glucose by the amylase in the
saliva
...
No digestion
happens here, it's just about a 25 cm long tube that connects mouth with stomach
...
The hydrochloric acid, pepsin and lipase chemically break down the food
and mix it with all the gastric juices to make chyme
...

Liver produces an alkaline solution called bile
...

Gallbladder stores the bile before it is released into the duodenum
...

Pancreas Production of lipase, protease and carbohydrase, which are digestive
enzymes
...
The liver, gallbladder and
pancreas do not actively digest, they are all attached to the small intestine
...
Fat
absorption happens here
...

Ileum absorption of bile and vitamin B12
Large intestine is responsible for processing waste, so emptying the bowl is easier
...

Goblet cells secrete mucus, to protect the colon from acid and gasses
...
The colon absorbs water from undigested food
and passes the waste to the rectum
...
When
the rectum wall stretches, we can feel that we have to empty the bowl

...
But anaemia can be fixed by taking iron supplements
or by changing your diet and having more iron rich foods
...
Taking large amounts of coffee, tea, dairy or
whole grain which has large amounts of phytic acid, can make it harder for the body
to absorb iron
...
The
calcium in your body helps keep healthy teeth and bones
...
A lack of
calcium could lead to rickets in children
...
Tiredness, itching, depression and anxiety
could also be related to a calcium deficiency
...
500g
...
The risk gets higher, when you eat very little, smoke or
have a long term dependency on drugs or/and alcohol
...
Vitamin C deficiency can be fixed by taking
supplements, or eating vitamin C rich food like citrus fruits, bell peppers, tomatoes
or strawberries
