What is digestion? Starting from mouth, state the various steps involved in digestion

The gastrointestinal system starts in the mouth. In reality, as soon as you eat the first bite, digestion begins here. Chewing splits the meal into sections that are easier to eat, and saliva combines with food to start breaking down the body into a shape that you can consume and use.

Explanation:

The mechanism of digestion can be divided into various phases, such as mouth, stomach, small and large intestine.

A complicated mixture of mechanical and chemical processes are used in digestion. The mechanism includes food intake and push, mechanical or physical digestion, chemical digestion, absorption, and defeat.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
