Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food.
How many types of digestion are there?
Digestion is the process of breaking down food into components the body can absorb. It consists of two types of processes: mechanical digestion and chemical digestion.
What is digestion short answer?
Digestion is how your body turns food you eat into nutrients it uses for energy, growth, and cell repair. The digestive tract (or gastrointestinal tract) is a long twisting tube that starts at your mouth and ends at your anus.
Where does digestion start?

What defines food?
Food, substance consisting essentially of protein, carbohydrate, fat, and other nutrients used in the body of an organism to sustain growth and vital processes and to furnish energy. …
What are the 3 types of digestion?
Mechanical digestion involves physically breaking the food into smaller pieces. Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells. Chemical digestion begins in the mouth when food mixes with saliva.
How do we digest food step by step?

Which type of digestion occurs in man?
extracellular digestionHumans use extracellular digestion when they eat. Their teeth grind the food up, enzymes and acid in the stomach liquefy it, and additional enzymes in the small intestine break the food down into parts their cells can use. Although fungi do not have a digestive tract like humans, they still use extracellular digestion.
What are the two types of digestion?
Digestion is a form of catabolism or breaking down of substances that involves two separate processes: mechanical digestion and chemical digestion.
What are the 4 stages of digestion?
There are four steps in the digestion process: ingestion, the mechanical and chemical breakdown of food, nutrient absorption, and elimination of indigestible food. The mechanical breakdown of food occurs via muscular contractions called peristalsis and segmentation.
What is the main function of the stomach?
Stomach. The stomach is a hollow organ, or “container,” that holds food while it is being mixed with stomach enzymes. These enzymes 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.
What is digestion why it is important?
Food and drink must be changed into smaller molecules of nutrients before they can be absorbed into the blood and carried to cells throughout the body. Digestion is the process by which food and drink are broken down into their smallest parts so the body can use them to build and nourish cells and to provide energy.
Does food go straight to your stomach?

What is difference between ingestion and digestion?
The main difference between ingestion and digestion is that ingestion is the taking of food into the body whereas digestion is the breakdown of food into small molecules that can be absorbed by the body. … In mechanical digestion, large food particles are broken down into small food particles.
What digestion occurs in the stomach?
In the stomach, food undergoes chemical and mechanical digestion. Here, peristaltic contractions (mechanical digestion) churn the bolus, which mixes with strong digestive juices that the stomach lining cells secrete (chemical digestion).
