Your body has two main ways of breaking down food to release nutrients:physical digestion – slicing, grinding, mashing and churning to break substances into smaller pieces and mix them togetherchemical digestion – using chemical reactions to convert substances into simpler chemicals that can be more easily absorbed by the bodyThe key difference is that in chemical digestion, new substances are produced. Substances that speed up chemical digestion are called enzymes. The video mentions that these are produced by bacteria in the large intestine, but some of our own organs produce them too.Question 12SavedRecall what happens in physical digestion.A chemical reaction takes placeNo new substances are producedAn enzyme converts one chemical into anotherFood is not broken into smaller pieces but just mixedI'm not sureQuestion 13SavedVenus flytraps produce enzymes to break down the bodies of the insects they catch.Determine which type of digestion this is.PhysicalChemicalI'm not sure

The process of mechanical digestion includesMultiple Choicethe breakdown of food particles by enzymes.physically making food smaller and easier to handle.the churning of food in the muscular stomach.the hydrolysis of nutrients.physically making food smaller and easier to handle and the churning of food in the muscular stomach.

Digestion is the breakdown of food molecules into smaller molecules that can be taken in by cells of the body. Digestive processes can be classified as either physical or chemical.Outline the importance of a high surface area to volume ratio in the small intestine for digestion.

What is digestion?a.It is the breaking down of food into molecules usable by the cell.b.It is a process of maintaining a stable internal environment.c.It is the process of taking in food
