PATH OF FOOD
Food → oral cavity (saliva secreted) → Teeth (break food) →
pharnyx → esophagus → stomach (enzymes, digest protein) →
small intestine (enzymes, digest most of the food, absorb
nutrients) → large intestine (defecation).
The path of food is one of the most important processes in our
body since it helps us to digest food, absorb the nutrients and
defecate the waste.
The digestion of food starts when food is chewed with saliva
secreted in the oral cavity.
The teeth would then break food into smaller pieces which help
our body to swallow food easily.
To swallow, the tongue pushes the food to the back of the mouth
and into the pharnyx, which is commonly known as a throat.
After entering the pharnyx, the food would move itself to the
esophagus, going directly to the stomach where the digestion of
protein takes place.
In here, the stomach, food would be mixed with the enzymes
which are the molecules that help chemical reactions to go faster.
After being liquefied with enzymes, the food leaves the stomach
and goes to the small intestine.
When food is stored in the small intestine, digestive enzymes
would be released to cut food into smaller pieces, which leads to
the easier process of nutrient absorption.
Once the nutrients have been absorbed, the food waste would
finally be pushed into the large intestine where defecation
happens.
In conclusion, because of the above important steps that a path of
food has, we should eat well and maintain a healthy lifestyle.
