The mouth and the stomach are two anatomical regions involved in the mechanical breakdown of food. In the mouth, teeth mechanically break down food into smaller pieces through mastication. In the stomach, muscular contractions churn and mix food with digestive juices to further break it down into a semi-liquid state.
oxygen from the air around us, and sunlight Oxygen does not break down our food, and neither does sunlight. The physical break down of food refers to the internal process. For example, Mastication and the secretion of bile and acids to aid digestion.

The mouth (by chewing) and the stomach (by gastric motion).

The mouth is involved in both chemical and mechanical breakdown of food. Mechanical breakdown occurs through chewing and mixing with saliva, while chemical breakdown is initiated by enzymes in saliva that start breaking down carbohydrates.
The digestive system is responsible for the mechanical and chemical breakdown of food. It includes organs such as the mouth, stomach, and intestines, which work together to process food into nutrients that the body can absorb. Mechanical breakdown involves chewing and mixing, while chemical breakdown involves enzymes and acids that help decompose food into simpler molecules. This system ensures that the body receives the necessary nutrients for energy, growth, and repair.

No. Most of the breakdown of food is done by the small intestine.
the acid involved in the breakdown of food in the stomach is Hydrochloric Acid (HCl)

Beyond being involved in the taste of food, sensory neurons do not have much of a role in breaking down food. The teeth do the grinding and the stomach is where most of the mixing takes place.
