What else can I help you with?
Is the small intestines chemical or mechanical?
The small intestine completes the process of chemical digestion.
Does the small intestine have mechanical or chemical digestion?
Yes, in part. Chemical digestion occurs in the mouth (saliva), stomach (gastric acid) and small intestine. The nutrients are mostly absorbed in the walls (lining) of the small intestine.
Where does chemical and mechanical digestion take place?
what is responsible for chemical digestion in earthworms
How is machanicle digestion different for cheminal digestion?
mechanical digestion is with your teeth , chemical digestion is in your stomach and small intestine.
Which organ in the digestive system is not involved in chemical or mechanical digestion?
small intestine
What is the initial site of mechanical and chemical digestion?
The mouth is the beginning of both mechanical and chemical digestion. Chewing breaks the food into smaller pieces and the saliva wets the food but also adds an enzyme called amylase that begins the digestion of carbohydrates.
What does the churning action of the stomach wall accomplish?
The churning action of the stomach wall accomplishes mechanical digestion. Mechanical digestion begins in the mouth and along with chemical digestion, ends in the small intestine.
Is the bile duct involved directly or indirectly in mechanical or chemical digestion?
Indirectly in chemical digestion by the release of stored bile into the small intestine. The bile then emulsfies fats.
What are the three methods of digestion?
ParastalsisChewing with teethBile and pancreatic juice secreted in the small intestine
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.
Where does most chemical digestion take place and nutrients are absorbed into the blood?
chemical digestion takes place in the small intestine large intestine,mouth and stomach. Nutrients are absorbed in the small intestine and minerals in the large intestine.
What do the large and small do for your digestive system?
The large intestine absorbs water, and the small intestine uses small finger like things called villi take the nutrients and take it through the small intestine's wall throughout your body. Both have chemical digestion and small intestion has mechanical digestion.
