ANATOMY

Detailed explanation-1: -Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion. The role of chemical digestion is to further degrade the molecular structure of the ingested compounds by digestive enzymes into a form that is absorbable into the bloodstream.

Detailed explanation-2: -As food travels from your mouth into your digestive system, it’s broken down by digestive enzymes that turn it into smaller nutrients that your body can easily absorb. This breakdown is known as chemical digestion. Without it, your body wouldn’t be able to absorb nutrients from the foods you eat.

Detailed explanation-3: -The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.

Detailed explanation-4: -Examples of physical digestion, also known as mechanical digestion, are the act of chewing, as well as peristalsis in the stomach.

Detailed explanation-5: -The answer is your digestive system, a collection of organs that break down food into smaller components that your cells can use. There are two main ways that digestion happens: physical and chemical. In physical digestion, your body mechanically breaks down food, grinding or smashing it into smaller pieces.
