The process of conversion of complex food substances to simple absorbable forms by mechanical and biochemical methods is called digestion.

What is the digestion process?
Digestive Processes
The processes of digestion include six activities: ingestion, propulsion, mechanical or physical digestion, chemical digestion, absorption, and defecation. The first of these processes, ingestion, refers to the entry of food into the alimentary canal through the mouth.
What is digestion one word answer? – Related Questions
Why is digestion important?
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.
What is digestion and types of digestion?
Digestion is a form of catabolism or breaking down of substances that involves two separate processes: mechanical digestion and chemical digestion. Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion.
What is digestion for Class 7th?
Digestion: The process by which food is broken down into simple absorbable substances is called Digestion. Digestion of food takes place in the digestive system. The digestive system is composed of the alimentary canal and associated glands.
What is digestion class 10th?
Digestion is the process of breaking down complex, insoluble molecules of food into smaller, simpler molecules which can then be readily absorbed by the body.
What is digestion Class 4?
The process of breaking down of food into simpler form is called digestion.
What is digestion Class 3?
The process of breaking down of food into smaller particles that can be absorbed by our bodies is called digestion. The organs involved in the process of digestion are mouth, food pipe (esophagus), stomach, small intestine, liver, pancreas, large intestine and anus.
Where does digestion end?
The digestive tract begins at the mouth and ends at the anus.
What is digestion Class 5?
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.
What is meant by digestion Class 6?

How do you feel when you are hungry Class 3?
How do you feel when you are hungry? Answer: When we are hungry, we feel very restless until we eat something.
How we taste and digest food?
Since our nose gets blocked when we have cold so we are not able to smell and taste food properly. (ii) It is said that digestion starts in the mouth because the saliva contains digestive enzymes. These enzymes help in digestion of the sugars by breaking them into simpler molecules.
Why should we eat proper food for Class 5?
Some nutrients give us energy to work and play, some help us to grow, and some help us to fight against diseases. Different foods have different nutrients. Thus, we should eat different food to remain fit and healthy.
What is main function of tongue in digestion?
A digestive organ, your tongue moves food around your mouth to help you chew and swallow. It also helps you make different sounds so you can speak and form words clearly. Your tongue helps keep your airway open so you can breathe properly, too.
Why is it better to chew slowly?
Chewing helps to signal the beginning of the digestive process. As your body releases saliva to help break down food, it also relaxes the stomach ahead of digestion to allow food and nutrients to pass through more easily. Chewing food slowly gives the stomach enough time to signal the brain for satiety.
Why am I full so fast?
Feeling full after eating very little
Possible causes of early satiety include gastroesophageal reflux disease, commonly known as GERD, and peptic ulcers. In some cases, a more serious problem — such as stomach cancer — could be a factor.

(BMI is a measure of body fat that takes into account a person’s weight and height.)
