Question

how digestive system works in humans body​

Answer 1

Answer:

The human digestive system is a series of organs that converts food into essential nutrients that are absorbed into the body. The digestive organs also move waste material out of the body. The enzymes in saliva help break down foods, and the lubrication function of saliva makes it easier for food to be swallowed.

The parts of the human digestive system are: The mouth and esophagus, The stomach, The small intestine, The large intestine, Pancreas, and the Liver.

Your digestive system is uniquely constructed to do its job of turning your food into the nutrients and energy you need to survive. And when it's done with that, it handily packages your solid waste, or stool, for disposal when you have a bowel movement.

We need food to fuel our bodies for energy, growth and repair. 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 digestive tract begins at the mouth and ends at the anus. It is like a long muscular tube, up to 10 meters long, with digestive organs attached along the way.

A large reservoir of microbes, such as bacteria, live within the large intestine and, to a lesser degree, in the rest of the digestive system. These bacteria play an important role in healthy digestion. The exact types of bacteria are particular to each person. Other factors that influence the type of bacteria in your digestive system include where you live in the world, what health conditions you have and what medications you have received.
