What takes place as food goes through the digestive system?

Answer 1

What happens is after you have chewed up all your food it will go down your gullet to your stomach where the food is broken down physically and has acids adds to it. Past your pancreas some of the food will go into one of your intestines (we have two) then into your blood as the rest will go to your other intestine and then down the toilet.

Answer 2

It gets passed down the esophagus by muscles, then the stomach churns the food. Then the energy from the food gets mixed in with the blood and flows all around the body. Then the things the body doesn't use is disposed of using the excretory system.

Our digestive system goes through 9 basic steps:

Teeth- Digestion starts here. The job of the teeth is to start tearing and crushing the food down into small enough pieces so that it can fit down our throats.

Saliva- The salivary gland in located underneath the back of our tongue. It creates our saliva or spit. This helps soften the food in the mouth so that it is easier to swallow. Saliva is also the first of several chemicals that start to break down foods into simpler forms.

Tongue- The tongue is a muscle that works with the food and saliva to form a "ball" that can be swallowed. Of course, the tongue also contains taste buds that helps us tell the difference between salty, sour, sweet, and bitter foods.

Esophagus- The esophagus is simply a transportation tube from the mouth to the stomach. When we swallow, what we are really doing is closing a trap door in our throat called the epiglottis. This sends food down the esophagus and prevents food from going down the trachea (or windpipe) and into our lungs. Food moves down the esophagus using muscles not gravity.

Stomach- The first stop after the esophagus is the stomach. Once the food gets to the stomach the stomach uses chemicals to try to make the food tinier. These chemicals are called gastric juices and the include hydrochloric acid and enzymes (chemicals that break down food). The food is moved around in the stomach and mixed with the chemicals for about 3 or 4 hours. When it is done in the stomach, the food is now a cream-like liquid call chyme. The food is still not small enough the get into our blood stream and it has not provided the body with anything useful yet. Now a valve at the end of the stomach opens sending the food past the liver.

Liver/Gall Bladder- At this point, our food is hit with more chemicals. The liver makes a chemical called bile but bile is not stored in the liver. Instead it is stored in the gall bladder. When the gall bladder mixes bile with our food, it does an important job: breaking down the fat (from milk, butter, cheeses) into tiny droplets. This fat will supply us with much energy later.

Pancreas- The pancreas also adds a digestive chemical as the food leaves the stomach. This digestive juice works on breaking down the carbohydrates (from breads, potatoes, etc.) and the proteins (from meats, cereals, peanut butter).

Small Intestine- The small intestine is the real hero of the digestive system. The small intestine is a tube that is about 22 feet long! This is where the real digestion takes place. As the food passes through, it is mixed with the new chemicals and soon our "food" is now digested small enough to be put to use by the body. Along the walls of the intestine are thousands of tiny fingers called villi. Blood vessels (capillaries) in the villi can absorb the tiny food molecules and send them off to the rest of our body through the blood.

Large Intestine- Whatever the body cannot put to use is sent to the large intestine. Many plants, for example, contain cellulose which cannot be digested. The big job of the

Answer 4

When you put your food in you mouth the saliva helps break down the starches, when food has been moistened and crushed it goes down the oesophagus and into the stomach. Here the juices from the stomach wall are well mixed with the food, helping to break down proteins into simpler forms to aid digestion. The starches continue to break down until the material in the stomach becomes too acidic. The materials in the stomach are churned about to mix the digestive juices well throughout the food. When the food becomed liquified it enters the small intestine. In the first part of the intestine, the duofenum, digestion continues. Juices from the pancreas and liver help to further break down the foods. The breakdown of proteins finishes here. Then fats are split into finer parts and starch digestion is completed here. It is also in the small intestine that digested food is absorbed into the blood and lymph. Finally in the large intestine, water is absorbed and the contents become more solid, so they can leave the body as waste material.

Answer 5

as the piece of food goes through each organ it gets smaller and smaller each time because of all the enzymes and acidsthat effect it!

Answer 6

after nutrients are broken down, they pass into the blood-stream and are taken to the body cells for use in the methabolism and growth.
