What process increases the surface area of foods prior to chemical digestion?
Mastication, or chewing, is a form of mechanical digestion that increases the surface area of foods prior to chemical digestion.
What are chewing and churning types of?
Chewing and churning are types of mechanical digestion. The other type of digestion is chemical digestion, which involves the breaking down of foods via enzymes.
What is the similarities between mechanical and chemical digestion?
They both break down food. Mechanical digestion literally breaks it down by grinding it. Whereas chemical digestion uses amylase (saliva that contains an enzyme) To break down the foods from starch to simple sugars.
What does mechanical digestion mean?
Mechanical digestion happens in only in 2 of your digestion organs mouth and stomach. Mechanical digestion is the mechanical way you digest your food for example when your eating your teeth are mechanical digesting your food by making your food smaller by chewing on it your not changing your food in any way that only happens chemical digestion is happening.Another example of mechanical digestion is in your stomach when the food is bong to the stomach your stomach is squeezing mushing up the food to make it smaller (your stomach is made out of 3 lairs of mussel's which squeeze in all 3 different direction's).
What is it called when it break down foods?
The mechanical shredding and crushing of food (together with the mixing in of salivary amylase to start digestion) is mastication.
Which of the following processes involves both physical and chemical changes?
Digestion of foods is chemical and physical (mechanical).
What is the meaning of Mechanical Digestion?
Tears, grinds and mashes large food particles into smaller ones. The size of the food is reduced, but the foods aren't changed into other compounds.
What type of foods don't require chemical and physical digestion?
all foods require either physical or chemical digestion.
Contrast mechanical digestion with chemical digestion and give an example of each?
Physical digestion is, basically, "mashing." The food is ground up (by the teeth), mashed into a paste (by the stomach), and so forth. It's mixed with other foods in the process, but no new molecules are produced. Chemical digestion involves chemical reactions, and new molecules ARE produced. The action of enzymes in saliva, gastric juices, and so forth is a form of chemical digestion.
What foods help the digestion?
fibre
What do enzymes help digestion?
Enzymes are involved in the digestion of all types of foods except, of course, the foods that cannot be digested (like cellulose).
Where does digestion?
Digestion begins in the mouth where saliva break down the foods into the bio-chemicals.
