Digestion takes place mainly in the small intestine by pancreatic enzymes eg trypsin or pancreatic lipase. but also a small amount takes place in the stomach by stomach enzymes eg pepsin or gastric lipase. of the lipase's pancreatic lipase is far more important in digestion of fats that gastric lipase. note that small amounts of starch digestion also takes place in the mouth due to the actions of amylase which is found in saliva. This action is short lived as the amylase action is abolished by the low pH of the stomach. No digestion takes place in the large intestine (aka the colon) as this is mainly for absorption of water and electrolytes.
In your small intestine, where your proteins, carbohydrates and lipids are finally digested into small molecules that can now be used for everyday processes in your body. The smaller molecules produced are anino acids, glucose, fatty acids and gycerol. Remeber that the fatty acids and glycerol are digested in the lacteal whilst the gluose is digested in the villi capillaries.
most of your food breakdown of food take place in you stomach
Initially, the mechanical breakdown of food takes place in the mouth via the teeth and tongue. Later, the mechanical and chemical breakdown of food occurs in the stomach.

Mechanical breakdown helps chemical breakdown because when you chew, chemical breakdown is going on all at the same time. So, that is going to chemical because if you didn't have saliva (chemical breakdown) if would take real long to digest your food.

Breakdown cover comparison is an insurance that provides assistance to vehicle owners who have had a breakdown. It will take care of most of your mechanical issues.
Primarily in the mitochondria, but also in the endoplasmic reticulum.

The function of the teeth is the mechanical breakdown of food. i.e. to chew and bite your food breaking it into smaller pieces to allow for it to mix with saliva. The smaller pieces also allow for the chemical breakdown of food by various enzymes to occur faster.
The oragan in which the most absorbtion of nutrients occurs is the small intestine.
The small intestine is where most of the food taken in by vertebrates is digested. It is also absorbed there.
Almost all of the food you take in is absorbed in the small intestine. Most of the water you drink is absorbed in the large intestine.
