What is a digestion short answer? ›

Digestion is the process of mechanically and enzymatically breaking down food into substances for absorption into the bloodstream.

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 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.

Digestion refers to the breakdown of food into smaller components that can be absorbed into the bloodstream.

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.

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.

The Digestive System is responsible for the breakdown of food in smaller components until they absorbed in body and generates energy. The tongue, salivary glands, pancreas, liver and gallbladder, intestinals etc are the imporatant parts of the digesion system.

Physical digestion is the mechanical breakdown of food. Physical digestion in the mouth includes chewing, which masticates, or grinds, food. Chemical digestion in the mouth is done by salivary amylase which is the enzyme in the saliva that breaks down complex carbohydrates into simple sugar.

Meat and fish can take as long as 2 days to fully digest. The proteins and fats they contain are complex molecules that take longer for your body to pull apart. By contrast, fruits and vegetables, which are high in fiber, can move through your system in less than a day.

As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.

The digestive system breaks down food into simple nutrients such as carbohydrates, fats and proteins. These can then be absorbed into your blood, so your body can use them for energy, growth and repair. Anything that isn't used is waste, and leaves the body as faeces (poo).

Your digestive system is a network of organs that help you digest and absorb nutrition from your food. It includes your gastrointestinal (GI) tract and your biliary system. Your GI tract is a series of hollow organs that are all connected to each other, leading from your mouth to your anus.

How does digestion work? Digestion works by moving food through the 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.

Ingestion can be referred to as an organism's consumption of a substance. In the case of human beings, when the food is taken in from the mouth and then masticated and swallowed for further processing, it is called ingestion. It takes place by absorbing substances by cell membranes in single-celled organisms.
