The long tube refers to the gastrointestinal (GI) tract, which is responsible for digesting food and absorbing nutrients. Within this system, food is broken down into nutrients primarily in the small intestine, where enzymes and digestive juices work to facilitate this process. The nutrients, such as carbohydrates, proteins, and fats, are then absorbed into the bloodstream to be utilized by the body for energy, growth, and repair.

Why does food stays in the organs so long?
Food stays in the organs for a relatively long time as it travels through the digestive system, where it is broken down and absorbed. The process of digestion takes time as the food moves through the stomach, small intestine, and large intestine, where nutrients are extracted and waste is processed. Efficient digestion is important for the body to extract the necessary nutrients from food.
What are 2 ways food is broken down in the stomach?
The stomach is a sac shaped like a "j" and is about eight inches long. In the stomach, food is mixed with acids. The muscles in the stomach move, which helps break down the food. The stomach is protected from the acid by a lining. From the stomach, the food pulp is sent to the small intestine. Food leaves the stomach a little bit at a time.
Can nucleic acids be broken down by the body to yield basic nutrients?
Yes. Nucleic acids are long polymers of nucleotides that are made up of a sugar, a base, and a phosphate group. The components of nucleotides could be used as nutrients.
A long coiled tube in which food is digested and absorbed?
The long coiled tube in which food is digested and absorbed is the small intestine. It is responsible for breaking down food into nutrients and absorbing these nutrients into the bloodstream to be used by the body for energy and other functions. The small intestine is an essential part of the digestive system, where most of the digestion and absorption of nutrients takes place.
How long does food stay in the mouth before passing to the next area?
Food does not stay in the mouth for long before passing in to the next area. Food is broken down somewhat in the mouth by saliva and chewing before passing into the alimentary canal.
Is the stomach part of the digestive system that is 7 meters long and helps to extract nutrients from food or the small intestine?
small intestines. ANSWER Your stomach is part of your digestive system. The main function of it is to store food, break it down and begin some absorption. It is not part of the small intestines which is 7 meters long and absorbs nutrients.
What is the long tube inside the body attached to the stomach where nutrients in the food are absorbed?
Small intestine is where 90% of nutrients are absorbed.
What is the functions and muscles in the digestive system?
First of all, the digestive system is full of organs, not muscles. Mouth- mechanically breaks down food by churning and cutting. Esophagus- the long tube the links to the liver, and passes the food down to then liver. Stomach- the holding place for the food for 4-6 hours. The food is then chemically broken down. Pancreas- functions to produce enzymes to send all over the body. Liver- produces bile Gall bladder- stores bile Duodenum- the small tube that links the small intestine and stomach. Small intestine- the 20 ft. Long tube that food passes through to get to the large intestine. Large intestine- the 4ft long tube that passes food to the rectum. Rectum- the place that stores food and waste. Anus- the opening and the end of the rectum that eliminates waste.
Why wouldn't the circulatory system be able to do its job without the digestive system?
The circulatory system relies on the digestive system to provide nutrients and oxygen from the food we eat. Without the digestive system breaking down food and absorbing nutrients, the circulatory system would not have the necessary fuel to transport to cells throughout the body. Thus, the two systems are interconnected and rely on each other to function effectively.
How does food turn into food?
Food is broken down in a process called respiration. Enzymes are usually involved in the breakdown of food. Proteins are broken to amino-acids by protease, Carbohydrates broken down to simple sugars e.g fructose and glucose and Lipids (fats & oils) are broken down to fatty acids and glycerol by Lipase. Once they are broken down, they are taken to the cells where they're respired to produce Energy, Metabolic water and carbon-dioxide.
What is the salivary gland's job?
there job is to produce saliva to help chemically break down your food. it would take a long time to break down all of your food without the salivary glands help. your food has to be broken down really good before it can travel to your stomach and go through the small/large intestine and out your back door....
How long does it take food to reach your intestine?
1 hour
