Where does mechanical digestion happen?
Mechanical digestion starts when food is chewed physically by the teeth (grinding and tearing the food), and the remaining steps of digestion continue from then on.
What kind of digestion involves the teeth tearing or grinding food into smal pieces?
mechanical processing
What function do the incisor teeth have that molar teeth do not?
incisors are for tearing food and molars are for mashing
What teeth are used for mashing food?
Premolars and molars are used for mashing and grinding food.. Canines are for tearing meat and incisors are used for cutting chunks of food off.
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 are the purposes of the various teeth in the human mouth?
the front teeth sre for ripping the food, the back teeth are for grinding the food
How does mechanical digestion in the small intestine occur?
Mechanical digestion involves breaking down food molecules without changing the chemical nature of the molecules in the food. No chemical bonds are broken in mechanical digestion. Tearing forces (e.g. teeth) or muscular movements (e.g. the stomach) can assist mechanical digestion. Chemical digestion, which requires enzymes, involves breaking the bonds within food molecules and thereby producing products that are chemically different from the substrate (reactant). The smooth muscle layers of the small intestine are not set up for mechanical digestion. There are only two layers of smooth muscle in the muscularis externa of the small intestine: an inner circular layer and an outer longitudinal layer. These two muscles are ideal for peristalsis. In the stomach, however, there is an additional third layer in the muscularis externa (an oblique layer). These three layers can move the contents in the stomach around in many different directions. The stomach, therefore, is much better suited for mechanical digestion.
Differences between physical and chemical changes?
A physical change is a change that does not change the chemical makeup of the substance. This can be crushing, tearing, or a phase change for example. A chemical change changes the chemical makeup of the substance. Some examples of this are rusting, combustion, or digestion.
When objects change by tearing crushing or melting but do not change into different substances a?
A physical change has occurred.
Why do dogs have both sharp and flat teeth?
Dogs have sharp teeth, like canines, for tearing and slicing meat, while flat teeth, like molars, are used for grinding and crushing food like bones or kibble. This combination of teeth allows dogs to efficiently capture, tear, and chew their food for digestion.
Examples of mechanical digestion?
in the Mouth the salivary glands secrete saliva and the saliva contains an enzyme called amylase amylase breaks down carbohydrates(starch) into dysacherides (two) and monosacherides they are simply sugars/glucosein the stomach the stomach has an acid called hydrochloric acidand it has an enzyme called pepsinogen. Hydrochloric activate pepsinogen into pepsin. Pepsinogen enzyme only works in an acidic environment and when it gets mixed with the hydrochloric acid it creates an enzyme called pepsin. Pepsin breaks down proteins into amino acid chains
What kind of crushing equipment would be most useful for tearing down a concrete wall?
A sledge hammer would be helpful.
