What are the functions of every organ in the digestive system?

Answer 1

1. Large Intestine: The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place.

2.**Stomach:**The stomach has 3 main functions: temporary storage for food, which passes from the esophagus to the stomach where it is held for 2 hours or longer. mixing and breakdown of food by contraction and relaxation of the muscle layers in the stomach. digestion of food.

3.Liver: The stomach has 3 main functions: temporary storage for food, which passes from the esophagus to the stomach where it is held for 2 hours or longer. mixing and breakdown of food by contraction and relaxation of the muscle layers in the stomach. digestion of food.

4.Small intestine:The small intestine carries out most of the digestive process, absorbing almost all of the nutrients you get from foods into your bloodstream. The walls of the small intestine make digestive juices, or enzymes, that work together with enzymes from the liver and pancreas to do this.

5.Large Intestine:The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place.

Answer 2

As soon as food enters the mouth, the brain sends signals to the saliva glands to produce more saliva. Saliva has enzymes and chemicals that automatically break down food and soften it. Teeth are also important in crushing the food. When you swallow the food, right beforehand, a protective flap closes over the windpipe. This flap is called the Epiglottis and it's important because it prevents food from going to the lungs. Occasionally though, the flap fails to close, most times when we swallow a liquid. This is what cause choking. Anyway, a serial of smooth unvoluntary muscle word together to sqeeze the food down in the esophagus then to the stomack. The stomach is also covered in layers upon layers of muscle. Inside the stomach are juices and mild acids that continously churn food even if there is no food. The inside of the stomach is also covered in a thick mucus that protects the stomach from digesting itself. It take about four hours to properly digest food. Even then, the body has not absorbed all the nutrients from the food. Food the passes to the small intestine where it's digested a little more. Here is where the rest of the nutrients are absorbed. Microscopic hair like villi take in the nutrients from the walls of the small intestines. Food that is not nutrient rich becomes waste and goes to the large instestines then out the anus.

Answer 3

i can answer this...

1st) MOUTH

-no digestion of protein and fats

-only digest carbohydrate

2nd) GULLET (Oesophagus)

-doesn't digest food

-only muscles that squeezes the food down the canal (gullet)

3rd) STOMACH

-produce gastric juice

-break down complex proteins into smaller proteins by enzymes in the gastric juice

4th) SMALL INTESTINE

-bile, pancreatic juice and intestinal present

-Bile is a greenish liquid made in liver and stored in the gall bladder (which means liver creates bile) It is released into the small intestine and breaks fat into small droplets which make them easier to digest

-Pancreatic juice is made in the pancreas and flows into the small intestine. ( Which also means pancreas creates pancreatic juice). It contain enzymes carbohydrase, protease and lipase.

-This enzymes digest fats and proteins and carbohydrate and completes the digestion of maltose.

-Foods stay in here for about 5 hours. The digested food will then pass through the wall of the small intestine into the blood vessels.

5th) LARGE INTESTINE

-Only food that cannot be digested reaches the large intestine. The undigested food then pass through the anus out of the body as faeces.

Answer 4

Your digestive system is uniquely constructed to perform its specialized function of turning food into the energy you need to survive and packaging the residue for waste disposal. To help you understand how the many parts of the digestive system work together, here is an overview of the structure and function of this complex system.

Mouth

The mouth is the beginning of the digestive tract; and, in fact, digestion starts here when taking the first bite of food. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.

Esophagus

Located in your throat near your trachea (windpipe), the esophagus receives food from your mouth when you swallow. By means of a series of muscular contractions called peristalsis, the esophagus delivers food to your stomach.

Stomach

The stomach is a hollow organ, or "container," that holds food while it is being mixed with enzymes that continue the process of breaking down food into a usable form. Cells in the lining of the stomach secrete a strong acid and powerful enzymes that are responsible for the breakdown process. When the contents of the stomach are sufficiently processed, they are released into the small intestine.

Small intestine

Made up of three segments - the duodenum, jejunum, and ileum - the small intestine is a 22-foot long muscular tube that breaks down food using enzymes released by the pancreas and bile from the liver. Peristalsis also is at work in this organ, moving food through and mixing it with digestive secretions from the pancreas and liver. The duodenum is largely responsible for the continuous breaking-down process, with the jejunum and ileum mainly responsible for absorption of nutrients into the bloodstream.

Contents of the small intestine start out semi-solid, and end in a liquid form after passing through the organ. Water, bile, enzymes, and mucous contribute to the change in consistency. Once the nutrients have been absorbed and the leftover-food residue liquid has passed through the small intestine, it then moves on to the large intestine, or colon.

Pancreas

The pancreas secretes digestive enzymes into the duodenum, the first segment of the small intestine. These enzymes break down protein, fats, and carbohydrates. The pancreas also makes insulin, secreting it directly into the bloodstream. Insulin is the chief hormone for metabolizing sugar.

Liver

The liver has multiple functions, but its main function within the digestive system is to process the nutrients absorbed from the small intestine. Bile from the liver secreted into the small intestine also plays an important role in digesting fat. In addition, the liver is the body's chemical "factory." It takes the raw materials absorbed by the intestine and makes all the various chemicals the body needs to function. The liver also detoxifies potentially harmful chemicals. It breaks down and secretes many drugs.

Gallbladder

The gallbladder stores and concentrates bile, and then releases it into the duodenum to help absorb and digest fats.

Colon (large intestine)

The colon is a 6-foot long muscular tube that connects the small intestine to the rectum. The large intestine is made up of the cecum, the ascending (right) colon, the transverse (across) colon, the descending (left) colon, and the sigmoid colon, which connects to the rectum. The appendix is a small tube attached to the cecum. The large intestine is a highly specialized organ that is responsible for processing waste so that emptying the bowels is easy and convenient.

Stool, or waste left over from the digestive process, is passed through the colon by means of peristalsis, first in a liquid state and ultimately in a solid form. As stool passes through the colon, water is removed. Stool is stored in the sigmoid (S-shaped) colon until a "mass movement" empties it into the rectum once or twice a day. It normally takes about 36 hours for stool to get through the colon. The stool itself is mostly food debris and bacteria. These bacteria perform several useful functions, such as synthesizing various vitamins, processing waste products and food particles, and protecting against harmful bacteria. When the descending colon becomes full of stool, or feces, it empties its contents into the rectum to begin the process of elimination.

Rectum

The rectum (Latin for "straight") is an 8-inch chamber that connects the colon to the anus. It is the rectum's job to receive stool from the colon, to let the person know that there is stool to be evacuated, and to hold the stool until evacuation happens. When anything (gas or stool) comes into the rectum, sensors send a message to the brain. The brain then decides if the rectal contents can be released or not. If they can, the sphincters relax and the rectum contracts, disposing its contents.

Answer 5

• Mouth: starts the process of digestion by breaking down food physically and chemically
• Esophagus: carries food from the mouth to the stomach through a process called peristalsis
• Stomach: secretes gastric juices to further break down food and kill bacteria
• Small intestine: absorbs nutrients from food through villi lining its walls
• Large intestine: absorbs water and electrolytes, and forms and stores feces before elimination through the rectum and anus
