What is the digestion short answer?
What Is Digestion? Digestion is the complex process of turning the food you eat into nutrients, which the body uses for energy, growth and cell repair needed to survive. The digestion process also involves creating waste to be eliminated.
The human digestive system consists of the alimentary canal and secretory glands. It consists of the (i) buccal cavity, (ii) oesophagus, (iii) stomach, (iv) small intestine, (v) large intestine ending in rectum and (vi) anus.
Answer: Digestion is the process in which the complex chemical compounds present in the food are broken down into simpler substances that are readily absorbed and utilized by the body.
The process of breaking down of food into simpler form is called digestion. As soon as we bite a food, such as a sandwich, it starts a journey through our digestive system. The entire process of digestion takes about 3-4 hours.
The process of conversion of complex food substances to simple absorbable forms by mechanical and biochemical methods is called digestion.
Digestion is the process by which food and drink are broken down into smaller parts so that the body can use them to build and nourish cells and to provide energy.
The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.
Why is digestion important? Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.
The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.
The process of converting complex food into simple and smaller units so that they can be easily utilised by the body is defined as digestion.
What is digestion Class 8 science?
Digestion - The chemical breakdown of food into small food particles for absorption. Secretion-It occurs by the epithelium of the digestive tract and by glandular organs.
Digestion- mechanical and chemical reduction of ingested nutrients which can be then converted to energy for use. Human digestive system- consists of the long alimentary canal that includes mouth, pharynx, oesophagus, stomach, small intestine, large intestine, rectum and anus.
Most noteworthy, digestion refers to the process of breaking down of food, so that it can be converted to energy. The mouth has saliva which softens the food and the tongue has taste receptors.
Digestion is the process of breaking large, insoluble food molecules into smaller molecules for absorption into the bloodstream. This process involves the use of many digestive fluids and enzymes such as saliva, mucus, bile and hydrochloric acid, among others.
ingestion, which includes chewing and swallowing. the secretion of substances that enable food and nutrients to move through the body effectively. propulsion, where muscles move the contents of the canal forward. digestion, the breakdown of food, for example, through chewing and secretions.
The human body uses the process of digestion to break down food into a form that can be absorbed and used for fuel. The organs of the digestive system are the mouth, esophagus, stomach, pancreas, liver, gallbladder, small intestine, large intestine and anus.
Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and chemical digestion. The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes.
The digestive system is made up of organs that are important for digesting food and liquids. These include the mouth, pharynx (throat), esophagus, stomach, small intestine, large intestine, rectum, and anus.
Digestion is a process that converts nutrients in ingested food into forms that can be absorbed by the gastrointestinal tract. Proper digestion requires both mechanical and chemical digestion and occurs in the oral cavity, stomach, and small intestine.

How does the stomach digest food?
The stomach is a J-shaped organ that digests food. It produces enzymes (substances that create chemical reactions) and acids (digestive juices). This mix of enzymes and digestive juices breaks down food so it can pass to your small intestine. Your stomach is part of the gastrointestinal (GI) tract.
Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.
After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. It takes about 36 hours for food to move through the entire colon.
Undigested food in your stomach can harden into a solid mass called a bezoar. Bezoars can cause nausea and vomiting and may be life-threatening if they prevent food from passing into your small intestine.

Motility, digestion, absorption and secretion are the four vital functions of the digestive system. The digestive system breaks down the foods we eat into energy our bodies can use.
Digestion is defined as the process of breaking down large, insoluble molecules of food into smaller, water-soluble molecules which can then be readily absorbed by the body.
2) Digestion- The process of breaking down food into molecules is known as digestion. 3) Absorption- The process of absorbing the digested food through the villi of small intestine is known as absorption. 4) Assimilation- The process of producing energy from the absorbed food is known as assimilation.
The digestive process begins in the mouth when a person chews. Additionally, saliva includes an enzyme that initiates the breakdown of food's carbohydrates. Saliva facilitates meal digestion and helps with the breakdown of carbohydrates.
The digestive system of humans consists of an alimentary canal and associated digestive glands. The alimentary canal consists of the mouth, buccal cavity, pharynx, oesophagus, stomach, small intestine, large intestine, rectum and the anus.
What are the 4 types of digestion?
Digestion systems are classified into four types: monogastric, avian, ruminant, and pseudo-ruminant.
The main organs that make up the digestive system (in order of their function) are the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus.
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
digestion, the breakdown of food, for example, through chewing and secretions. the absorption of nutrients, which mainly occurs in the small intestine. defecation and urination, the removal of waste products through the rectum and the bladder, respectively.
- Mouth.
- Esophagus.
- Stomach.
- The small intestine.
- Colon (large intestine)
- Rectum.
The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces. An acidic environment is needed for the digestion that takes place in the stomach.
Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.
