To further clarify:
Mechanical: The stomach is a muscular sack. It contracts and relaxes, sloshing and squeezing the food inside to break it down and to ease the job of the 'chemicals'. Another example is how many birds swallow stones to enhance the crushing and churning in their stomachs.
Chemical: The conditions and enzymes within the stomach contribute to chemical digestion. Hydrochloric acid, for example, creates an acidic environment that denatures proteins; whilst enzymes such as pepsin react at a molecular level with peptides to cleave them apart.
The stomach uses both mechanical and chemical digestion. It uses mechanical when it contracts and squeezes the food, mashing it further and uses chemical when stomach acid further dissolves the food.
what is responsible for chemical digestion in earthworms
No, it is chemical digestion.
Both the mouth and the stomach perform mechanical and chemical digestion.
Stomach
mechanical digestion is with your teeth , chemical digestion is in your stomach and small intestine.
Chemical Digestion. Mechanical digestion is the chewing of your food while chemical digestion is the processes that further break down the food like your saliva and stomach acids.
no in the mouth
Peristalsis. The movement of muscles bringing the food to the stomach.
The churning action of the stomach wall accomplishes mechanical digestion. Mechanical digestion begins in the mouth and along with chemical digestion, ends in the small intestine.
Yes, in part. Chemical digestion occurs in the mouth (saliva), stomach (gastric acid) and small intestine. The nutrients are mostly absorbed in the walls (lining) of the small intestine.
the stomach
the pharynx act is a connecting tube from the mouth to the stomach providing mechanical propulsion
