Why is the Digestive System important?

Answer 1

Food, on its own, is not in a form where your body can use it. Food needs to be broken down into small molecules of nutrients for the body to be able to absorb it. The digestive system processes food into useable nutrients and distributes them into the blood stream to go to different parts of the body.

Answer 2

The digestive system enable people to absorb nutrients from the food that they eat.

The digestive system starts at the mouth with teeth breaking down food into basically bite sized chunks, enzymes in saliva assist int he process; other teeth assist to make break the food particles into smaller pieces which are then swallowed.

Food then passes through the stomach, small and large intestine on the way out. Different portions of food and liquid are absorbed by the different portions of the systems as the food is processed.

Without a properly functioning digestive system we would end up with nutrient disorders or at worst starve to death.

Answer 3

The Digestive System is IMPORTANT for the digestion and absorption of food.OUR DIGESTIVE SYSTEM is very important because of the Protein, Carbon Dioxide, and fats in our body that come from the food that we eat everyday. They are changed into smaller molecules/nutrients before they can be absorbed into the blood and carry the cells throughout your body. And sooner or later it'll go through the excretory system to eliminate your waste(s).~Arigatou Gozaimasu/ Jeongmal Gamsahabnida/ Xiè Xiè~

Answer 4

The digestive system has two main jobs. Firstly, as the name suggests, it is responsible for the digestion (breaking down) of macromolecules such as proteins and lipids into smaller nutrients like amino acids and fatty acids/glycerol, using enzymes. The second crucial function of the digestive system is to absorb the micromolecules into the bloodstream, for transport around the body. It's all well and good breaking down nutrients, but if they can't reach the cells where they're needed, the entire digesting process is pointless! Absorption is carried out predominantly in the small intestine.

Answer 5

You would be dead without it... no way to eat or convert food to energy... no energy to function = no life....

Digestion is the mechanical and chemical breaking down of food into smaller components that can be absorbed into a blood stream, for instance. Digestion is a form of catabolism: a break-down of larger food molecules to smaller ones.

In mammals, food enters the mouth, being chewed by teeth, with chemical processing beginning with chemicals in the saliva from thesalivary glands. This is called mastication. Then it travels down the esophagus into the stomach, where hydrochloric acid kills most contaminating microorganisms and begins mechanical break down of some food (e.g., denaturation of protein), and chemical alteration of some. The hydrochloric acid also has a low pH, which is great for enzymes. After some time (typically an hour or two in humans, 4-6 hours in dogs, somewhat shorter duration in house cats, ...), the resulting thick liquid is called chyme. Chyme will go through the small intestine, where 95% of absorption of nutrients occurs, through the large intestine, and are excreted during defecation.[1]

Answer 6

If we don't digest our food, we wont't get the nutrients we need...eventually we will die of build-up of solid food and lock of vitamins and nutrients if we don't have our digestive system.

Answer 7

so you could swallow your food much easier =:)

Answer 8

because we wont eat without it
