The only mechanic part of the digestive system of animals are the mouth/teeth or the crop in animals with no teeth.
The small intestine completes the process of chemical digestion.
Saliva begins the chemical digestion of starch. It also is important for the success of mechanical digestion of the mouth, but does not, in its own, perform mechanical digestion.
Both the mouth and the stomach perform mechanical and chemical digestion.
Peristalsis. The movement of muscles bringing the food to the stomach.
the stomach does have both chemical and mechanical digestion. Mechanical-the walls of muscle in the stomach push food back and forth Chemical-digestive chemicals rain from try walls and breaks down big food molecules to smaller ones
The large intestine primarily absorbs water and electrolytes from undigested food, with little to no involvement in chemical or mechanical digestion. Its main role is to form and store feces before they are eliminated from the body.
While the pharynx and esophagus do not perform any mechanical or chemical digestive processes, they provide a critical service for the digestive system. They move food from the mouth to the stomach.
No. Anything involving a chemical is not mechanical. It is chemical. It this case a liver "chemical" like enzymes would be involved in the process of digestion. The mechanical process is what you would see when you chew your food, for example. You are not actually changing the food but making the larger parts smaller.
chemical work, transport work, mechanical work
When you move, chemical energy stored in your muscles is converted into mechanical energy, which powers your motion. This conversion allows your muscles to contract and your body to perform physical tasks.
Coal is a chemical compound which contains chemical energy. To convert coal into mechanical energy, you use it (burn it) to produce heat and use the heat to boil water, the steam from which will drive a steam engine which delivers mechanical energy.
Chemical energy from food is converted into mechanical energy and heat when you are active. The mechanical energy is utilized to perform physical tasks and movement, while some of the energy is lost as heat during metabolism.
