teeth
Compare and contrast mechanical digestion and chemical digestion?
Mechanical Digestion (or physical digestion) is more about the mouth. It's chewing, biting, breaking down, and sofening the food. This is why its called "Mechanical" Digestion.Mechanical digestion involves the pulverizing and crushing of food particles, usually by chewing. Chemical digestion occurs through the secretion of digestive juices.
Is the esophagus chemical digestion or mechanical digestion?
No chemical or mechanical digestion occurs in the esophagus, only propulsion, which is one of the six digestive processes.
Does the small intestine have mechanical or chemical digestion?
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.
Which type of digestion occurs in the mouth when an individual chews a piece of bread?
The type of digestion that chewing is referred to as is mechanical digestion.
Where do most mechanical digestion takes place?
In the Mouth then the second is the Stomach
What type of change that occurs in mechanical digestion?

Peristalsis. The movement of muscles bringing the food to the stomach.
What two simple machines are found in your mouth?
Scientifically, there are no literal "machines," in your mouth. There is mechanical and chemical digestion that occurs in your mouth. The enzymes are chemical. The mechanical are your teeth. Hope this helps.
What part of the digestive system do the mechanical digestion?
Mechanical digestion primarily occurs in the mouth and stomach. In the mouth, teeth break down food into smaller pieces through chewing, while in the stomach, muscular contractions help further break down food into a semi-liquid mixture called chyme.
What type of digestion occurs when whewing food?
Mechanical digestion.
What is the mechanical degestion?
Mechanical digestion is the physical process of breaking down food into smaller pieces without altering its chemical structure. This process begins in the mouth, where chewing occurs, and continues in the stomach through churning and mixing with gastric juices. It increases the surface area of food, making it easier for enzymes to act during chemical digestion. Overall, mechanical digestion is essential for efficient nutrient absorption in the digestive system.
